Unless your Ryobi is the right angle motor
(not sure if Ryobi even makes one), it is probably fairly gutless. Try using a big right angle model like the one I linked too. Of course you can always go up to an 8" softpad sander setup, but then there's no random orbit and the learning
curve goes way up. Unless you are experienced with that sort of tool I'd stick with a quality 5". In our yard I would expect this job to take two employees two full days, ie 32 man hours, tops, on an approx. 40 sail boat. And that's with 180. I would think you should be able to 60 grit off a hull
pretty quick, as long as you have basics like decent scaffolding. If you just want to remove paint
quickly and are planning on high build anyway, the soft pad could easily do the job in one day.
