170N is recommended for most offshore sailors, offering excellent lift and performance. 

Harness Release System (HRS)

Spinlock’s optional Harness Release System allows the wearer to detach from a safety line in an emergency. This innovative system uses a soft loop attachment point that can be released instantly by pulling the activation handle.

• Activation handle sits behind the soft loop — easy to find and pull
• Soft loop detaches, separating the user from the safety line
• Can be reset for continued use after activation
• ISO12402-1 approved deck safety harness

The HRS system provides a simple, intuitive method of releasing the harness without relying solely on a knife. It ensures compliance with lifejacket standards while offering a safer alternative when a sailor becomes trapped or dragged alongside a vessel.

Inflation System: UML Pro Sensor ELITE

The Deckvest 6D uses the UML Pro Sensor ELITE automatic inflator — a compact, reliable system activated by water flow.

• Newer, lighter, and shorter than the original Pro Sensor inflator
• Water-sensitive paper capsule dissolves when submerged, triggering inflation
• Designed to activate only when water flows upwards through the unit — spray and rain won't trigger it
• Dual indicators clearly show CO₂ cylinder status and firing head readiness
