A liferaft painter is commonly about 10 metres of wet polypropylene and can be under extreme tension; in an abandonment scenario the ability to sever that line cleanly and quickly is critical to avoid entanglement and speed evacuation.

Testing focus and operational priorities

Testing conducted by Ben Lowings concentrated on the single most likely lifesaving task: cutting a liferaft painter. The assessment emphasised speed and reliability when slicing through wet, slippery polypropylene under tension, ahead of secondary tasks such as cutting jackstays, severing a lifejacket tether, or sawing through high-tensile knots. Practical boating logistics call for a blade that will perform under stress without adding further risk: no sharp points near the neck, secure retention in a sheath, and a design that suits the user’s handedness and typical boat layout.

Core features to prioritise

  • Blunt-ended, serrated blade — safer around the neck yet effective on rope.
  • Locking mechanism — prevents accidental closure under load.
  • Coatings and materials — stainless or Teflon coatings resist corrosion in a marine environment.
  • Sheath and mounting — accessible at the companionway but secured to prevent accidental snagging.
  • Lanyard or tether — keeps the knife attached to the person during waves or in the water.
  • Ambidextrous handling — important when crew composition varies.

Legal and regulatory context

Under SOLAS there is no statutory requirement for pleasure vessels under 13.7 metres LOA to carry a knife, but the RYA recommends a knife as part of safety equipment for cutting ropes and rigging. UK law restricts carrying knives in public; RYA guidance, developed with police input, states carrying a knife while travelling specifically to a boat is considered reasonable, but leaving a knife in a vehicle glovebox as a general precaution is not a legal justification. Common sense and clear storage protocols remain essential for both compliance and safety.

Practical storage and placement

A common but risky pattern is a permanently mounted boat knife by the companionway that becomes corroded and blunt. A preferable approach combines a well-maintained sheath at an easily reached location with personal access to a separate, blunt-ended personal knife worn on a secure lanyard. Avoid exposed pointed daggers near transition points where crew move between deck and cockpit.

How the blades performed in real-use trials

Field trials focused on time-to-cut, control under tension, and resistance to corrosion after simulated salt exposure. Blunt-ended serrated blades generally outperformed plain-point blades on painter cuts: the serration grips polypropylene fibres and slices efficiently, whereas plain edges can slip on wet line. Locking folders with robust liners provided positive one-handed deployment, an important capability when a crewmember must cut while bracing.

Maintenance and lifecycle

Saltwater causes pitting and loss of edge retention. Regular rinsing, light lubrication, and periodic honing preserve performance. Replace or service knives that show significant blade pitting or compromised locking action — a corroded mechanism may fail when you need it most.

Choosing for your cruising profile

For short-day trips a single well-maintained blunt serrated knife kept on a lanyard is often sufficient. For bluewater cruising, combine that with a sturdier fixed or locking folder in a protected companionway sheath, and keep a clear maintenance schedule. Consider training drills for crew so everybody knows where knives are stored and how to use them safely under stress.

At a glance: choose a blade that balances cutting efficiency with safety and corrosion resistance, match mounting to the boat’s traffic flows, and enforce common-sense carriage and storage rules to stay within regulations and reduce onboard risk.
