When you’re looking for a useful marine tool to carry on board your boat, you need to take quite a disciplined approach (advice that applies equally to anyone buying gifts for boaters). Yes, a multi-tool with seven million functions can be very attractive, but do you really need to pluck your eyebrows at sea? Probably not - and even if you did, the prospects of levering out a pair of mini-tweezers with the end of a cold, briny fingernail on a wildly tossing boat are very slim indeed. What you need is something much simpler and much more marine-specific.

Best marine tools to take afloat

That means marine tools that are made of corrosion-resistant materials, with quick access, easy stowage, an efficient cutting blade and proven safety features. If it also boasts bright colours and buoyant construction so you can retrieve it when it falls overboard, so much the better. A serrated edge is by far your best bet for cutting rapidly through the fibres of a rope, while a blunt nose on the blade is often best for the avoidance of accidents on a moving boat. If you go for a folding knife, it should ideally be deployable with one hand and if you go for a fixed blade, it should come with a sturdy sheath that enables you to keep it about your person and access it at speed.

As a powerboater, you might not expect to get involved in any splicing, but a marlinspike remains a very useful tool for helping loosen off a knot in a line. Similarly, a shackle key (or shackle opener) is a great asset for operating the screw-pin shackles on marine rigging. A bottle opener, a screwdriver, an adjustable spanner and a pair of pliers can also be very useful assets on a boat but it is often best to split these into a separate tool kit (see for example: Guide to choosing good marine electrical tools), enabling your immediate quick-fix tool to be smaller, simpler and more portable. Here are a few of the best marine tools...

(3) Ocean Safety Fixed Floating Knife


Ocean Safety floating knife

Ocean Safety's fixed floating knife: inexpensive but well conceived.



Despite its modest price, this is a very well conceived tool for powerboaters. Developed for use in and around inflatable structures (like the tubes on a RIB) it comes with a buoyant, brightly coloured plastic handle and a safety-conscious rounded end. At around £7 it’s great value - and there’s also a folding version for about £4 more, see Ocean Safety.
Price:
£6.99

 

(4) Force 4 Race Rescue Knife - Blunt Tip


Force 4 rescue knife

Force 4's Race Rescue knife – designed in conjunction with the RYA.

It comes with a shackle key and an easy-drain plastic sheath that can be fixed in the cockpit or attached to your belt.
Price:
£39.95


 

(5) Gill Marine Tool

Currey Lockspike captain

Currey Captain – famous British brand made in Chichester.



Built by famous British marine brand, Currey of Chichester, the Captain is a traditional stainless steel pocketknife with a locking spike, a shackle opener and a sliding knot cotton lanyard to keep it safe. It’s top kit but if you want to save about £6, the original (and equally well-equipped) ‘Bosun’ has been a well-loved classic ever since its introduction in 1940.
Price:
£34.95

 

(7) Gerber River Shorty


Gerber Shorty knife

The Gerber River Shorty: simply well designed for cutting and surviving the harsh marine environment.

Bear Grylls Pack: not exactly marine specific, but this 12-piece multitool kit is good-looking for sure.



Built by Gerber, this Bear Grylls branded pack includes a 12-component multi-tool, flashlight and fire starter rod. It comes sheathed in a locking carrying case that attaches to a belt - and while it’s not marine specific, it’s a swanky looking kit that would look very plush mounted beneath your dash.
