If you are going to have battery operated tools make sure you have spare batteries and aither a 12-volt charger or an inverter to run your 110-vot charger. Be careful with the inverter, they tend to eat current like you've got a 100-mile extension cord to your battery charger. Also I've found that a tool that will remove screws with stripped heads was very useful (think I got it in Sears). Also for your wrenches and sockets, check what sizes you need and get multiples of each otherwise you'll find that the one you need has been eaten by the boat.
