Ceramic cam 0814 mr

Ceramic coatings on components within Spinlock rope holding devices are suited to hybrid rope coverings containing Vectran, Technora, Kevlar, or PBO.  The material properties of these fibres make them harder to grip, as they are effectively more “slippery”, which can compromise the load holding that can be achieved using the standard anodised surface finish.  To reach the max working load of the Spinlock jammer or clutch, with a hybrid covered rope, ceramic coated components which have a rougher surface texture providing better grip should be used.

The ceramic coating is more aggressive with the rope covering, but these exotic fibres are much more resistant to damage and therefore suitably matched for use with the ceramic coating.  The ceramic parts are not suitable for use with pure polyester covers which may be susceptible to damage at load limits.  Spinlock jammers or clutches built with hard-anodised jaws or cams are capable of achieving the max working loads when paired with 100% polyester covered ropes.  Both hard anodised and ceramic versions of components are made from the same raw components which then go through either the hard-anodising process or the ceramic coating process. 

The ceramic coating is also more resistant to wear and heat, making them ideal for high speed/high load lines, and they also grip the loaded line sooner when tension is transferred from the winch to the jammer or clutch.  This reduced ‘take up’ characteristic of the ceramic coating offers a significant benefit in performance. By minimising take up losses, the load left on the line after transfer is higher with ceramic components than with the anodised components. For the sailor who is seeking to find performance gains by upgrading sails, spars and to high tech ropes, upgrading rope holding equipment should be considered.

Although we do not market ceramic technology as having any increase in maximum load holding over the anodised, typically we do see an increase of 5 -20 %, depending on the rope being used.  Max load holding is very sensitive to different materials, diameters and rope manufacturers and Spinlock choose the MWL to represent an achievable level of performance across the spectrum ropes available on the market, rather than the absolute maximum level achieved in testing on the best performing rope.

Spinlock are proud to support a number of charities and organisations. The focus of our charitable support is in areas aligned to our business and our employees.

Involvement in the Community: In the areas where we are based, we encourage partnerships with local community organisations, schools and colleges to support numerous projects. Employees are encouraged to be involved in their local communities, through volunteering or fundraising and to make use of the company's payroll giving facility.

At Spinlock, we recognise that the benefits are mutual; employees are proud of helping to improve and support communities, which in turn helps them to develop their own skills and experience. We have employees who are local school Governors, board members for local nurseries, who help run local sporting clubs and who give talks and demonstrations for schools and local groups.

During 2011 we launched our Employee Charity Panel to encourage and support more staff to get involved with their community. Employees can apply for funding (monetary, product or time) to support any charity or community initiative they are personally involved with. These applications are reviewed by the Panel who meet half yearly to allocate funds to the charities who they think will benefit the most.

GCA Sailing has made Greig City Academy the first inner-city London school to have its own sailing club. 5 self-renovated craft and 1,000 sailors strong. The only London comprehensive school with its own fleet, students each year are taking on the challenge of sailing for the first time.

A maritime charity that teaches yachting, sailing and watersports courses to all levels and abilities from learning to sail to a career in yachting. UKSA offer practical solutions to help change young lives.

Ellen MacArthur Cancer Trust takes young people aged between 8 and 24 sailing to help them regain their confidence on their way to recovery from cancer, leukaemia and other serious illness.

People living with or affected by cancer on the Island can access professional and confidential counselling, befriending and complementary therapies at their Isle of Wight Cancer Support Centre. They offer some transportation options to help people attend hospital appointments, including the much relied upon Daisy Bus running from the ferry crossing to the mainland hospitals.

Ryde Rowing Club is one of the Isle of Wight's oldest sports clubs having been in continuous existence since 1877, providing facilities for competitive and recreational rowing as well as social facilities.

In 2018 the Spinlock team raised £5,006.02 taking on the Seafarers UK 24 Peak Challenge. Seafarers UK is a charity that has been helping people in the maritime community for over 100 years, by providing vital support to seafarers in need and their families.

Spinlock allows staff paid leave to donate blood. Giving blood saves lives. The blood you give is a lifeline in an emergency and for people who need long-term treatments. The service requires around 135,000 new donors a year to replace those who can no longer donate.

Spinlock sponsors the under eight-year old’s football team. The team play on the school football field on Saturday mornings. allowing children to have a fun, enjoyable introduction to football.

The Isle of Wight Christmas Toy appeal brightens Christmas for less fortunate children living on the Isle of Wight. These are children that for a variety of reasons are finding Christmas tough; perhaps a family bereavement or another crisis in their lives, maybe their family cannot afford gifts. Working with the IOW Council and local charities the Toy Appeal can ensure that the donations reach the children who need them most.

The Rotary Christmas Shoebox Appeal has been running for over 25 years and is a popular date in the Spinlock calendar with staff and their families getting involved every year. Many Spinlock parents say the task of gathering items to donate to children less fortunate is a tangible activity to get children involved with charity. In 2019 we collected 35 boxes at Spinlock HQ, Cowes.

EPIRB-PLB and AIS devices have decreased in size and price over recent years, making them increasingly popular with sailors, recreational water uses and those working on or close to water.

Spinlock Deckvest 5D lifejackets feature a mesh pocket on the outside cover which can be used to hold a EPIRB-PLB or AIS device. The Deckvest 5D features attachment points for the Chest Pack, specifically designed for keeping essentials such as a EPIRB-PLB or AIS close to hand. As well as the Chest Pack, the Essentials Pack range includes the Belt Pack and Side Pack, which can be attached to the belt of any Deckvest or other manufacturer's lifejackets.

A number of AIS devices are marketed as being able to integrate into a lifejacket, with some automatically activated by the lifejacket inflating.*   The Kannad R10 AIS device has been tested to integrate with a Deckvest lifejacket and Kannad have published a document on their own website detailing fitting of a Kannad R10 AIS device into a Deckvest lifejacket. This document can be downloaded from the link below.

The Ocean Signal AIS MOB1 unit has been designed with fitting to the Deckvest Lifejacket in mind and can be fitted to an existing Deckvest or purchased already fitted within the product. Read more here.

*Please note that the integration of an EPIRB-PLB or AIS device with a Deckvest lifejacket is at the owner's liability. Spinlock accept no responsibility for the performance of any EPIRP-PLB or AIS fitted into a Deckvest lifejacket or for any damage caused to the Deckvest lifejacket as a result of having fitted an EPIRB-PLB or AIS unit to a Deckvest.

Hardware FAQs

I have changed my halyard and now my clutches won't hold the new rope

The greater the line diameter, the greater the load holding. If you have reduced the rope diameter then you may need to consider either a rope core insert or sleeved cover to increase diameter in the clutching area. Your rigger will be able to arrange this. When rope is produced some lubricants are used in the manufacture, which can often effect rope holding performance. These lubricants can be washed out of the rope in the clutching area and once removed performance should improve. Check also the clutch or jammer is free of dirt and debris and parts not showing signs of wear.

What are the benefits of Ceramic coated Cams, Bases and Jaws in my Rope Holding Products?

Ceramic coated parts create a rougher surface texture on the gripping surface. As well as improved take up of a loaded line, this offers more consistent rope holding on performance line covers containing fibres such as Vectran, Technora, Kevlar and PBO. A 15-20% improvement in rope holding can be expected. Ceramic coatings also provide greater resistance to wear and heat which can build up during frequent high speed manoeuvres. Generally, if you have upgraded to higher performance lines containing specialist fibres it is recommended that the Cam, Base or Jaws is also upgraded to match this modern rope technology.

Ceramic Cam and Base upgrades are available for the XCS, XTS and XX clutches and Ceramic Coated Jaws Sets are available for XX and ZS rope holding ranges.

Can you convert a single unit clutch to a double or triple unit?

It is not possible to convert clutches into different configurations

What lubrication should I use on my clutches?

Spinlock recommend using fresh water to remove dirt and debris from your rope holding products. Remove ropes and flush with as much water as possible. On XAS, XTS and XCS clutches a light grease can be used on the handle bearing to keep a smooth action. ZS Jammers as well as benefiting from plenty of water flushing also require a light grease on the upper and lower bearing surfaces. With all Spinlock rope holding products, routine maintenance will help give consistent rope holding.  

Why do you recommend Silicone sealant as opposed to polyurethane or polysulphide?

Pure silicone is recommended for mounting clutches and Jammers to seal fastener holes against water ingress. Polyurethane and polysulphide as well as being an adhesive can also damage plastic parts they come into contact with.

Will RP25 rope coating improve my rope holding performance?

RP25 rope coating helps improve the interaction of the rope cover and rope core, which will in turn offer better rope holding performance in clutches and jammers.

Can I use 6mm line in a PXR0810?

6mm line can be used in the PXR0810, but like in all rope holding products, best load holding performance is achieved the greater the diameter of the line.

Do newer model clutches use the same drill template as older models?

Most newer model spinlock clutches use the same drill template as older models that they are updating, but customers should always check by downloading the latest drill template from the website. 

What is the difference between a clutch and a jammer?

Clutches allow the line to be released by opening the handle and the handle can be opened under load. Spinlock recommend taking the load safely on a winch, even when using a clutch. With a jammer the load will always end to be taken safely on a winch before the jammer handles can be opened and rope released. 

Sense Load Cells - Calibration

•  ISO9000 and many other standards specify the maximum period between re-calibration as once every two years and more frequently if the instrument deterioration is significant during that period (typically more than 1%.)

•  Many load cell users adopt an annual calibration as the standard interval to ensure that measurements are always as accurate as possible, which is particularly important if they are being used for safety critical applications.

•  However, although many load cell users choose annual calibration, very few do a comparison between the current calibration and the previous calibration to determine the degree of accuracy drop-off.

•  This is a highly useful exercise, as the results can be used to determine a more suitable re-calibration time period, which may be even be more frequently than one year if the load cell is being used in a particularly harsh environment or arduous operational conditions (high vibration levels, excessive cyclic loading).

•  If the load cell is used infrequently, it may not be necessary to re-calibrate it every 2 years. The accuracy required for each load cell’s specific application, and risks associated with it’s use, should also be considered when deciding how often to re-calibrate a unit. 

Spinlock is an independent and innovative company, widely acknowledged as the world expert in ropeholding. Based in Cowes, UK, the 'Home of Yachting', Spinlock has over thirty years experience of designing and manufacturing rope holding equipment for sailing boats, from dinghies up to the largest superyachts.

Spinlock’s cleats, clutches and jammers hold ropes from 2mm to 32mm in diameter and loads up to 12,000kg. The expert skills of our Special Projects Team are valued by America’s Cup, Volvo Ocean Race and other leading racing teams, Open 60’s and superyacht captains for the originality of their custom rope handling solutions.

Spinlock's Deckware Series includes the award winning Deckvest - the world leading lifejacket harness. Where there had been no significant technical or aesthetic change for over thirty years Spinlock developed a completely new and personal lifejacket harness solution that was attractive and comfortable to wear. Active campaigning by Spinlock about the Deckvest and the importance of wearing your own lifejacket harness has helped encourage a much more positive attitude towards sea safety. Power or sail, amateur, professional or commercial, wearing a well-fitting personal lifejacket has now become the norm.

Since 2010 we have been proud to supply special Deckvest versions to the International Certified Instructors of the highly regarded Royal Yachting Association. Other personal protection equipment widely used at top races and regattas are Spinlock Performance Safety Lines, Mast Pro Harness, ZERO Buoyancy Aid and the award winning lightweight lifejacket, the Deckvest LITE.

My Deckvest 5D and Deckvest LITE label states 150N buoyancy, yet the packaging states 170N?

The Deckvest 5D and LITE are tested to a standard of 150N - the minimum buoyancy of the category - and we are required to state this on the label. The Deckvest 5D and Deckvest LITE have an actual buoyancy of 170N. 

The Deckvest 5D is also available in 275N buoyancy for certain applications.

Should I buy a 170N or a 275N Deckvest?

170N is the accepted standard for recreational sailing. It is a comfortable, wearable size that is not too intrusive and it provides significant buoyancy when in the water.

The 275N provides significantly more buoyancy so is suitable for situations where additional weight might be carried, i.e. tools, steel toecap boots, etc.  Remember additional buoyancy and size is not always an advantage as it is heavier to wear and harder to use in the water, i.e. if entering a life raft, etc.

The Volvo Ocean Race sailors helped in the design and development of their lifejacket harness for the 2017/18 race and chose to wear 170N. 

What size Deckvest 5D should I buy, 1, 2 or 3?

The Deckvest 5D is available in 3 sizes. See here for size guides.

The size 2 Deckvest will fit the majority of customers – around 85 % of our Deckvest sales are a Size 2.

The Deckvest LITE and LITE+ are available in one size.

The Deckvest CENTO is one size, specifically for junior users aged 8 to 15 years old weighing from 20-50kg. 

What is the difference between a 5D and VITO?

The Deckvest VITO was developed using all the features, technology and development from the Volvo Ocean Race Deckvest, the trialled and tested VITO gives confidence and design innovation to benefit the sailor.

Comfort, Fit and Adjustment immediately stand out as key features. Easy to put on, easy to adjust to size and with a fully tailored fit, VITO feels lightweight and compact. 

The structured shape means the VITO doesn’t get tangled, can be put on quickly and easily, even in the dark. The VITO is fitted with the latest Spinlock Buckle System and a Coarse and Fine size adjustment ensuring a secure and comfortable fit every time it’s worn, even with cold, wet and tired hands. 

The Deckvest 5D is the original Spinlock lifejacket, available in 2 bladder sizes: 170N and 275N with Pro Sensor Elite operation system. The Deckvest VITO has a Hammar operating system and is 170N of buoyancy.

Read our handy lifejacket comparison chart here.

The VITO article here.

What is the difference between Deckvest 5D and LITE?

The Deckvest 5D is a high specification lifejacket with integrated deck harness. It comes fitted as standard with these features.

The Deckvest LITE is an ultra lightweight lifejacket which may be used for a wide variety of applications, from inshore sailing, RIB, powerboat, fishing, kayaking, paddleboarding and more. You may add to the LITE many additional features depending on the application; including Sprayhood, Pylon™ lifejacket light, Lume-On™ bladder illumination lights. You can also convert this product easily to manual only operation if required. 

Does the the Deckvest LITE have a integrated deck harness?

The Deckvest LITE has no integrated deck harness. 

For an offshore lifejacket with harness see the Deckvest 5D. For a deck harness only, see Deck-Pro.

The Deckvest LITE+ is an update to the popular LITE with an added Deck Harness.

Can I wear the Deckvest LITE+ on an Atlantic crossing?

You could technically wear a Deckvest LITE+ on an Atlantic crossing as the Deckvest LITE+ is a 170N lifejacket with integrated harness, however it does not come fitted with any accessories. These accessories would be vital during an Atlantic crossing.

The following accessories are fitted as standard to our offshore lifejacket harness the Deckvest 5D; sprayhood, Pylon approved lifejacket light, Lume-On bladder illumination lights and safety line cutter, as well as a whole host of other features e.g. double crotch strap and visible activation window.

The Deckvest 5D 170N and the Deckvest LITE+ both contain a 170N bladder and are tested to the same standards; CE Approved, ISO 12402-3 Lifejacket (170N) and ISO 12401 Deck Harness.

You can add the accessories to the Deckvest LITE+ but at which point this would cost the same as the 5D. You may also find the 5D more comfortable, we find offshore sailors prefer the rugged fit of the 5D as it has been designed for offshore sailing vs the LITE+ which was designed with inshore sailors in mind, who may occasionally require the added security of a harness.

How do you to fit the thigh straps or order replacements

There are fitting videos on our YouTube channel and replacements can be ordered through your local store or online.

Choosing between the Hammar Hydrostatic or UML Pro Sensor Elite inflation system

Both inflation systems are very effective but are suitable for different situations. In general, the Hammar system is better suited to very wet conditions as it relies on water pressure to activate.

The UML system is easier to service and parts are more readily available around the world. They are also very resistant to wet conditions - check out the “How Water Sensitive is a Deckvest Pro Sensor 170N Lifejacket?" video.

For more inflation system information see Lifejacket Inflation Systems Explained.

Can I convert my UML Pro Sensor Elite inflation system to Hammar Hydrostatic inflation and vice versa?

No. Unfortunately you cannot do this because they are very different units.

See here for more information on Inflation Systems.

When does the CO2 cylinder expire?

CO2 cylinders do not have an expiry date. We recommend if there is any corrosion on the cylinder it is replaced as this may indicate leakage and the corrosion can damage the bladder fabric. CO2 Bottles can also be weighed to check for leakage, the correct net weight is written on the cylinder.  

When does the UML Pro Sensor ELITE inflator expire?

The expiry date is printed on the firing head unit, this date usually allows 3 years from date of purchase

When does the Hammer Hydrostatic Inflator expire?

The hammer inflation unit expires 5 years after manufacturing. The expiry date is printed on the unit. 

Which re-arming kit do I need, and how do I fit it?

The product pages specify the part number of the re-arming kit that you will need for you Deckvest lifejacket. The UML re-arming kit fits both the Deckvest Pro Sensor and Deckvest LITE lifejackets. Instructions for fitting can be found on the product packaging and in the Spinlock videos.

I find my Deckvest is uncomfortable, have I fitted it correctly?

Correctly fitting and adjusting your Deckvest is key to its comfort. The Spinlock range of lifejackets are designed to be incredibly comfortable and lightweight so they can be worn for extended periods of time. 

Ensure both waist and back adjustment have been used (if applicable). Typically, Deckvest lifejacket should sit higher up the body, the front almost in line with the sternum, and the top should shape and fit around the shoulder, not sitting on the neck. Please see the Spinlock videos to ensure you have it correctly fitted.

The size guide will also help you check you have the correct size product.

Servicing: Where, How, When?

The Deckvest is designed to be easily check and maintained by yourself. Follow the videos online for basic and more detailed checks. 

We recommend that you check your Deckvest at least once a season and before any long passages.  If you would rather a professional looked over it then there is a list of approved Deckvest service centres here.

Servicing your Deckvest Lifejacket

It is recommended that you carry out a complete self-inspection annually, checking:

a.  The outer cover fabric: for cuts, tears, abrasion and damage caused by heat, chemicals etc.

b.  The lifejacket bladder: check for leaks by inflating your lifejacket through the oral tube until firm and leave for 24hrs. Any loss of firmness indicates leakage and means it is unsafe. To check the oral valve, fully inflate the lifejacket and hold the tube under water. If bubbles appear, deflate and re-inflate to test.  If a leak persists, do not use your lifejacket until it has been professionally serviced at your nearest service centre.

c.  The components: remove and inspect all components for signs of damage or contamination.  For example, ensure the CO2 cylinder is screwed in tight and the activation head also screwed tight.

We recommend a professional service at a service centre every two years. If you would prefer to use a Spinlock approved service centre these are listed in the Service Centre locator section of our website.

Can the bladder be repaired or replaced?

We do not recommend that a punctured bladder is repaired. However, if your Deckvest has the “button in” attachment on the lifejacket then we can supply a replacement bladder for you to fit. 

I’ve broken my zip, can it be fixed?

The zips on the Deckvest are plastic to ensure they do not corrode. However, they can break if they are snagged or forced. It is possible to replace the slides. Please contact us for spares and instructions.

The elastics on my Mast Pro Harness have worn out.

Non-skid decks and salt water can take a toll on elastics. Replacement leg strap elastics are available here.

Can I fit a new battery to my Pylon Lifejacket light?

Pylon light batteries may expire prematurely if stored in damp areas causing the light to activate unintendedly.  The Pylon light batteries cannot be replaced as it is a watertight unit. Complete units can be purchased here.

Can I clean contaminants from my Deckvest?

Paint, oils and chemicals can quickly damage the bladder of the lifejacket and we advise replacing the cover if it encounters contaminants. Use of harsh cleaning products may cause greater damage to the Deckvest. We recommend the Pro-Tech cover to wear over the Deckvest if frequently working in dirty work environments. More information on our commercial products can be found here.

Can I fly with my Deckvest?

Although it is often raised as an issue at check in, International IATA regulations state that you can fly with two lifejackets and two re-arming kits as long as they are declared at check in. See Flying with your Deckvest for more information and to download our document to show your airline.

When does the Warranty period start and what is covered.

The 5 year (if registered with TLS) warranty period starts from when you purchase the Deckvest. See Warranty for more details.

How many years service can I expect from my lifejacket?

Spinlock offer a 5 year warranty on our leisure inflatable lifejackets. Spinlock do not offer a service of lifejackets over 10 years old and this is common to most service centres. At this age it becomes very difficult to guarantee the durability of all of the fabric and strong parts.  If you feel that your Deckvest Lifejacket has had very little use, then you are able to inspect and self service the lifejacket yourself in order to extend its life, but this is completed at your own risk.

Are the Deckvest 5D, LITE, CENTO approved to SOLAS?

No – SOLAS is a commercial standard for abandonment lifejackets. The Deckvest is tested to the International ISO12402 standard that covers wearable lifejacketsSpinlock have launched a Deckvest SOLAS 275 Twin Chamber lifejacket which is designed for commercial use.

Manufacturing Dates

There are several dates printed on the Deckvest. The date on the inside label shows which quarter of which year the lifejacket was completed. Harnesses are often made in large batches earlier whilst firing caps are added at a later date than this to ensure that they reach the stores with the maximum lifetime on them.

Lifejacket vs Buoyancy Aid

WING & FOIL buoyancy aids (also known as PFDs - Personal Flotation Devices) assist with buoyancy, you must be a competent swimmer as they only aid you in the water. Lifejackets are tested to a standard which requires that the lifejacket turns an unconscious casualty over to allow them to breathe.

Is the Deckvest 5D Lifejacket Harness USCG Approved ?

The Deckvest 5D Lifejacket Harness is approved to the International ISO12402 standard for lifejacket design and manufacturer. The USCG Approval is different and whilst the Deckvest 5D Lifejacket Harness exceeds this standard many of the great features of the Deckvest 5D Lifejacket Harness would need to be removed to meet the USCG Standard.

Spinlock sell many thousands of Deckvest 5D Lifejacket Harness in the USA every year to customers who want to enjoy the design, comfort and features of the lifejacket, a lifejacket approved to the ISO12402 Standard, who then carry old or basic USCG lifejackets to meet local carriage requirements.

Spinlock Deckvest lifejackets use a range of inflation systems.

Watch the video below for detailed information on Spinlock inflation systems.

Deckvest VITO 
The Deckvest VITO lifejacket harness uses a Hammar Hydrostatic pressure system. 

Deckvest 5D

The Deckvest 5D lifejacket harness uses a Pro Sensor (Pre-October 2018) or Pro Sensor Elite (Post October 2018) firing system. 

Deckvest 5D HammarⓇ (product discontinued, re-arming kits still supported.)

Deckvest LITE & LITE+
The Deckvest LITE lifejacket uses a water activated UML Mk5 paper coil inflation system. 

Deckvest LITE USCG
The USCG Approved Deckvest LITE (available to purchase in USA only) uses the water activated Halkey Roberts Alpha Auto Inflator.

Deckvest CENTO 
The Deckvest CENTO junior lifejacket harness uses a water activated UML Mk5 paper coil inflation system.

ALTO Belt Pack
The ALTO uses a 16g cylinder and manual Halkey Roberts inflation system.

The Deckvest SOLAS 275 twin chamber lifejacket uses two UML Mk5 paper coil inflation systems. The SOLAS 275 is fitted with 2 inflation systems. You may require 2 x 60g cylinders and 2 x firing caps.

The DURO+ lifejacket harness is fitted with the Pro-Sensor/Pro-Sensor Elite

DW-RAK (MK5i and Pro Sensor Pre-October 2018)
DW-RAK/E170 (Pro Sensor Elite Post-October 2018) 

The DURO lifejacket uses a water activated UML Mk5 paper coil inflation system. UML MK5i is fitted as standard. The Pro-Sensor/Pro-Sensor Elite is available as an upgrade on lifejacket purchase, please check which model you have.

Mk5 operating system

Lifejacket Inflation Systems Explained

UML Mk5 Inflator 

This is a water sensitive activation system that uses a compressed paper capsule which dissolves when wet which then releases a spring to puncture the CO2 cylinder.

The cap is designed so that only water flowing upwards through the unit will cause it to activate. Water, spray and rain running down the jacket will not cause activation. 

Elite 5 x 7 mr

UML Pro Sensor Inflator ELITE

The Pro Sensor Elite® Automatic Inflator replaces the Pro Sensor® Automatic Inflator late in 2018. 13mm shorter and 4 grams lighter than the original Pro Sensor® Automatic Inflator.

This is a water sensitive activation system that uses a compressed paper capsule which dissolves when wet which then releases a spring to puncture the CO2 cylinder.

The cap is designed so that only water flowing upwards through the unit will cause it to activate. Water, spray and rain running down the jacket will not cause activation.

The Pro Sensor has two indicators that show the status of the CO2 cylinder and firing head.

The UML Pro Sensor is a very reliable system which is easy to check and re-arm. It is also easy to convert to manual firing only. Re-arming kits for this inflation system are stocked by most marine stores.

3 year expiry date on firing head from manufacture. 

Hammar operating system

HammarⓇ Hydrostatic Inflator

The HammarⓇ inflation system is activated by water pressure and will not inflate until the cap is approximately 10cm underwater. 

This system is designed for use in more extreme conditions and extended offshore sailing.

The benefit of the HammarⓇ system is that the jacket cannot accidentally inflate from being wet with rain and sea spray.

The unit has a single indicator to show if armed, and has a 5 year expiry date.

Delayed inflation can be caused if full immersion of the firing head is delayed by buoyant foul weather clothing.

Hr firing head 6 x 4


Halkey Roberts Alpha Auto Inflator

The USCG Approved Deckvest LITE uses a water activated Halkey Roberts Alpha Auto Inflator that is designed so that only water flowing upwards through the unit will cause it to activate. Water, spray and rain running down the jacket will not cause activation. 

Pro sensor operating system

Old style UML PRO SENSOR INFLATOR FOR DECKVEST 5D 170N / 275N, DURO+, replaced with the new Pro Sensor Elite® late in 2018.

This is still supported, see upgrades and spares.

Pro Support

The marine environment is very harsh on soft materials and your Deckvest lifejacket will last for much longer if cared for. 

Simple care involves wiping with a damp sponge to remove salt and dirt before drying in an aired room. More detailed care can be undertaken following some simple steps which are detailed in the instruction book.

You will find a range of videos on inspecting and caring for your Deckvest on the Spinlock YouTube channel.

Proposition 65 requires businesses to provide warnings to Californians (State of California USA) about significant exposures to chemicals that cause cancer, birth defects or other reproductive harm.  These chemicals can be in the products that Californians purchase, in their homes or workplaces, or that are released into the environment. By requiring that this information be provided, Proposition 65 enables Californians to make informed decisions about their exposures to these chemicals.

Spinlock products contain very very small amounts of ingredients that are listed under Proposition 65 and as a result we have placed the following warning on our products

Clutches and jammers have always been a simple and cost effective rope holding solution when compared to a winch and, more recently, halyard locks.  

Halyard locks, and the benefits in reducing mast compression, are a key component of many competitive boats and are now being more widely used on large performance cruising boats.  A halyard lock is the equivalent of a traditional mainsail tack pin, just at the top of the mast. However, the use of a lock does require you to hold and adjust the full sailing load at deck level, using a clutch or jammer.  With the advent of new sail designs, especially downwind sails, with most requiring extremely high luff loads, clutches and jammers are now being worked harder by another corner of the sail, namely the tack.  Locks are not suited to tack applications because with mast rake changes, different types of sail carried and trimming requirements, infinite adjustment is often required. Using a clutch or jammer, these adjustments can be controlled in the normal way at deck level. 

On a number of recent high performance multihulls (including the AC45's) the downwind sails are permanently attached to the bow furler, because its not practical to go out onto the bowsprit during a race.  In cases like these,  jammers have been used at the mast head to provide a variable locking position and are operated remotely from the deck on a trip line, just like a lock.  This approach is working for a number of larger yachts were it is notoriously difficult to dimensionally control and set a sail between two points over forty metres apart and even harder to get the inboard reefs to fit.

Remote operation of clutches and jammers is now common on board many performance yachts.  The first boats to embrace remote operation were the IMOCA 60's for end of boom reef jammers and tack line jammers mounted on the bow.  More recently the focus on aerodynamic efficiency of deck layouts has forced designers to run sheets and halyards underdeck when possible.  The TP class has led the way with remotely operated under deck spinnaker sheet clutches and pit clutches buried in the coach roof.  Mini Maxi designs are following suit by utilising side mount, bonded, remote operation XXC ceramic and titanium clutches and ZS jammers.  

With the holding capacity of clutches almost doubling over the past 5 years, many applications can now be held with the convenience of a handle operated unit rather than a winch release jammer. This has been particularly helpful for use on tack lines for spinnaker drops were the tack release is critical for a fast and safe drop, whether by hand or winch driven.  Larger and offshore yachts carefully consider the properties of the load holding equipment they require and often reduce the load holding required with a purchase, therefore allowing a particular clutch or jammer to be used.  The very latest Volvo Ocean Race 65 has been careful planned between sailors, running rigging experts and the designer, resulting in cost effective and 100% race proven solutions which work for both inshore and offshore with the removal of a single purchase. 

The Spinlock high load product range, especially rope holding equipment, has developed rapidly in the last few years providing lighter, stronger and more adaptable products, without the need of expensive customisation, all with ever increasing load holding capacity.
