These are all great lists. Put your list together based on what you feel comfortable fixing (better be a pretty good list here!) In addition to the great bunch of hand tools above, you may want some power tools. My skipper
(wife) gave us the complete Milwaukee 29 volt set. No worry about shock using these. note also the special winch
driver attachment in the 1/2 inch right angle drill. There is enough reserve in this tool for my wife to drive me to the top of our 89 foot mast
as well as dousing the #1 jib
There is no way to have too many tools. Also make sure you have spares, hoses, gaskets, gasket
sealers or all the tools are not much help. We carry abut a cubic meter of hoses of various size and type. Take also a wide variety of hose clamps. You can buy nice sets of SS clamps from McMaster Carr on line.
When we bought our boat the PO left about 50 # of SS nuts, bolts, washers etc. I sorted thes all into smaller compartmented plastic boxes. We also inherrited about a bushell of marine
rated wire of different gauge.
If you plan to service
etc. make sure you have the manuals
As far as a tool list is concerned, make sure there is a wrench in your kit for every fastener you can find. Remember, guys seldem have legitimate excuse to buy nearly any tool we see.
