There's a particular kind of lifejacket you forget you're wearing - right up until the moment it matters. The Crewfit 165N Sport is built to be exactly that. Crewsaver have managed to pack a full suite of safety features into one of the slimmest, lightest profiles on the market, and the result is a jacket that genuinely earns its place on deck.

The Fusion 3D technology is what sets the fit apart. Rather than a flat, one-size-feels-like-none design, the bladder is shaped to follow the contours of the body, reducing bulk at the chest and keeping the jacket feeling snug rather than cumbersome. Add in the centre buckle adjuster and crotch strap, and it stays exactly where it should - even in rough conditions.

On the safety side, Crewsaver haven't cut corners to achieve that compact profile. The bladder shape is specifically engineered to rotate an unconscious wearer into a face-up position, with light and hood attachment points already built in. The EXOLOK indicator gives instant visual confirmation that the 33g CO2 cylinder is correctly fitted and hasn't been tampered with - a small detail that makes pre-sail checks considerably more reliable. Automatic inflation means no fumbling for a pull cord if you go over the side unexpectedly.

The harness version adds a stainless steel buckle and soft-loop D-ring for tethering to a jackstay or safety line, making it the sensible choice for offshore passages or anyone sailing short-handed.

FAQs

What is the difference between the Crewfit 165N Sport with harness and without harness?
The harness version of the Crewfit 165N Sport includes an integrated safety harness with a stainless steel buckle and a soft-loop D-ring, allowing you to clip a tether to a jackstay or safety line. The non-harness version is otherwise identical in buoyancy, fit, and inflation mechanism. The harness version is recommended for offshore sailing, single-handed sailing, or any conditions where there is a meaningful risk of going overboard.

What is EXOLOK on a Crewfit lifejacket?
EXOLOK is Crewsaver's cylinder status indicator. It provides a clear visual signal if the CO2 inflation cylinder has moved, become unscrewed, or been tampered with. This makes pre-use checks quicker and more reliable - if the indicator shows the cylinder is out of position, you know before you need it.

What is Fusion 3D technology in a lifejacket?
Fusion 3D is Crewsaver's bladder shaping technology. Rather than a flat inflatable chamber, the bladder is contoured to follow the shape of the wearer's torso. This reduces bulk across the chest, improves comfort during extended wear, and gives the jacket a more tailored, fitted feel compared to standard lifejacket designs.

Is the Crewfit 165N Sport suitable for offshore sailing?
The Crewfit 165N Sport with Harness is suitable for most coastal and offshore recreational sailing. The 165N buoyancy rating meets the requirements for open sea use, and the integrated harness allows tethering to a jackstay. For extreme offshore or heavy weather passages where a higher safety margin is needed, a 275N or 300N rated lifejacket may be more appropriate.

How often does the Crewfit 165N Sport need to be serviced?
Crewsaver recommends annual inspection of the Crewfit 165N Sport. The first two annual checks can typically be carried out as self-service inspections, with a full service by a certified agent recommended at the three-year point. Always inspect your lifejacket before each use and rearm it promptly after any inflation.

What CO2 cylinder does the Crewfit 165N Sport use?
The Crewfit 165N Sport uses a 33g CO2 cylinder. Replacement rearming kits - including the CO2 cylinder and automatic firing mechanism - are available separately and are a recommended stock item for any serious sailor.
