Spinlock’s latest award winning performance lifejacket harness with the Pro Sensor Automatic Inflation System.

Take a look at some of the videos to see how comfortable, easily adjusted, re-armed, and importantly - resistant to manual inflation these vests are ... you'll never want to take it off!

This is the 275N commercial version of the jacket, with larger bladder providing additional buoyancy for those heavily loaded with gear or looking for the additional buoyancy.   You don't need the additional buoyancyfor leisure sailing and racing, check out the 170N version.

The Spinlock Deckvest is a high performance auto inflating life jacket and harness designed with comfort and safety in mind - you'll want to wear it!  The deckvest has a compact, moulded cut-away shape and a new proprietary shoulder fit system to flex and locate for the ultimate in comfort for men and women.  

The deckvest includes a built in harness, with a soft, high tensile fibre connector loop for your tether, and the high intensity Pylon Light for all-round visibility - a light on an antenna holding the strobe above your head. 

The deckvest is approved to the ISO 12402-3 (Life Jacket) and ISO 12401 (Deck Safety Harness) International Standards and comes with a 5 Year Warranty from date of first registration.

If you are on a very wet boat, then you'll want to consider the Hammar activation head in your deckvest (Spinlock Deckvest Hammar).

The ProSensor System Explained

Deckvest 5D 170 Pro Sensor Firing System is activated by contact with water. A compressed paper element dissolves to release a sprung needle which pierces the gas cylinder.

Sea, spray, or rainwater running downwards through the unit should not cause activation-only water flowing upwards will activate firing ... take a look at the short video of the 'fire-hose' test where a lucky test subject is fire-hosed with their deckvest on to demonstrate the protection against inadvertent inflation.


  • Very reliable activation when immersed
  • Easy to check and re-arm at sea
  • Easy to convert to ‘manual firing’ only
  • Pro Sensor has an indicator to show armed status
  • Water sensitive activation system 
  • Uses a compressed paper capsule that dissolves and releases a spring to puncture the gas cylinder. (Pro Sensor has indictators to show status of cap and 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 jacket will not cause activation. 


  • Can be prone to accidental inflation in heavy breaking sea conditions or if stored in a damp, unventilated location 
  • Cylinder can work loose over time so needs checking regularly 
  • Cylinder can corrode/leak if stored damp 
  • 3 year replacement date printed on firing cap
