Re: power tool voltage for cruising: 12V or 18.5V or 110V AC?
The lithium ion 18 volt tools are fantastic, I carry a drill and impact driver on the boat all the time. Massive power and long battery life. My little Makita drill is as powerful as any 115v drill I have. The Lithium batteries don't seem to discharge while not being used like the other 18 volt batteries either. I also like how compact the tools are for getting into the convenient(?) spots where most repairs seem to take place on boats.
