5. vise (cause after hitting your fingers 4 times trying to hit something with a hammer they start getting sore).
but seriously, in dire straights, I don't think too many people are going to be bothered to use a micrometer.
generally gets twisted together, crimped if the connectors are handy, but if the straights are dire you might have more important things to do than soldering.
Multimeters are great, test lights work well enough in a lot of cases.
I can't think of where more than 2-3 pulleys would be used on a boat, and what emergency
someone would have to start pulling them. And anything along this line of repair will require a good set of wrenches, and maybe sockets and a ratchet.
Torches are a potential danger
Bolt cutters big enough to go through rigging
Grinder (the 3 1/2 or 4 inch hand held angle grinder kind). with sanding
disk and cutoff wheel
. But it's not going to do much without AC around. The first time I started to do some fiberglass
repair I discovered this was indespendible. And maybe a sawzall.
And pliers and vise grips of assorted sizes and shapes, goes along with the screwdriver and hammer in the basics category.
