10 Essential Boat Tools & Supplies

If you're a boat owner, know that stuff is going to break, often in the most inconvenient times and places. You may not be able to prevent some mishaps from occurring, but you can be prepared for them when they do. 

Part of being prepared is never leaving shore without bringing some essential tools along for the ride. You don't need to haul a heavy mechanic's tool cabinet on board, but every boat owner should have at least a handful of basic tools at their disposal at all times. Here are some essential boating tools to always carry onboard.

1. Pliers

Probably the most versatile tool found in any toolkit, pliers can be used for almost anything, including securing loose bolt heads, clamping hoses, or crimping pipes.

2. Adjustable Wrench

Another versatile tool to have on a boat, an adjustable wrench is indispensable when it comes to tightening and loosening nuts and bolts, but can also be used to clamp and crimp if necessary.

3. Small Socket Set

A socket set makes short work of freeing up corroded nuts and bolts. Small socket sets should be adequate enough, but make sure the set includes a spark plug socket. If it doesn't, then carry a separate spark plug wrench.

4. Screwdrivers

Screwdrivers are also essential tools for a boat. An onboard toolkit should include a Phillips, a Torx and a flathead screwdriver. If your boat has hex screws or bolts, you will also need a set of hex keys.

5. Utility Knife

A retractable utility knife is another must-have tool on a boat. It'll cut through rope, pipes, plywood and fiberglass if the need arises.

6. Hammer

It doesn't need to be a 10lb monster, but a small hammer is always handy to have around for flattening/straightening metal or helping to free heavily corroded bolts.

7. Multimeter

Electricity and water are not best buddies, and electrical failures are not uncommon on boats. A multimeter will make identifying and diagnosing electrical issues much simpler.

8. Spray Lubricant

Spray lubricant is another multi-use item that should be in every toolkit. Commonly used to penetrate and help loosen corroded nuts and bolts, spray lube is also excellent at displacing water, which prevents electrical shorts and corrosion.

9. Electrical Tape

Have you ever tried fixing an electrical problem without electrical tape? When it comes to electrical mishaps, a roll of electrical tape or a can of liquid electrical tape can make the difference between getting stranded on the water or cruising right along.

10. Duct Tape

Is there anything duct tape can't help fix? A roll of duct tape is useful for taping up just about anything, and comes in handy during emergencies.
