We know there’s not a lot of space in the average vessel, but the last thing you want is to cut your day short because an essential tool isn’t aboard. For the best shot at a satisfactory fix, stow tools, parts, and accessories that correspond with your boat’s set-up in a waterproof box or compartment:

Adjustable wrenches

Cable ties

Caulk

C-clamps

Clothespins

Cotter and clevis pins for sailboats

Cutters

Drive sockets

Duct tape

Flashlights and batteries

Fuses

Hoses and clamps

Safety glasses

Screwdrivers

Screws, snaps, bolts, and nuts

Sockets

Spare belts if you have an inboard

Spark plugs and wires

Whether you fix the problem or end up being towed in, have a skilled mechanic look at your DIY handiwork before you make another boat trip.
