Re: What's in your tool box?
On a small boat space is limited, but I would still recommend using a small plastic tool box or fishing tackle box to store the tools onboard. Choose one that has no or very limited holes in the lid or the bottom to keep water out. I like small fishing tackle boxes due to all the small sections useful for separating screws, bolts, wire, etc. The big tools go in the bottom. Give everything in the bottom a nice spray of WD40 once in awhile to keep stuff from getting rusty and stiff. At a minimum I can't imagine going anywhere on any boat without: channel lock pliers, small and medium vice grips, several screwdrivers philips and regular, needle nose pliers, a couple of adjustable wrenches, wire stripper and connector crimper tool, a sharp knife, electrical tape, a hammer, and a multimeter. If you want to work on the motor a small 3/8" socket set will be needed, spark plug tool, and oil, etc. I would also store someplace else on the boat in ziploc bags: gorilla tape, some electrical wire, some SS wire, some black wire ties, some silicone self-welding tape, some silicone sealant, some teflon tape, etc. Contrary to what some others say, on a larger cruising sailboat you can never have enough tools and spares. I would have a hard time getting everything on my 38-foot sailboat into the trunk of my car. I have tools stored all over the boat and multiple tool boxes for various things.
