The last time I stripped the bottom, used an orbital d.a. sander with a big shop vac attached. Getting a large shop vac attached and then dragging around a big vacuum hose is a PITA but a powerful vacuum really keeps the dust contained as long as you have the right disks with the holes lined up. An open coat 80 grit or so takes the paint off very, very quickly. With my old boat, I'm not concerned about maintaining a glassy gel coat so a rough grit is not an issue. Don't know if this would work with a fine grit to maintain a slick gelcoat but I suspect fine 220 or so disks would clog very quickly. In that case, a chemical remover would probably be the way to go. Will have to give one of those razor scrapers a try as mentioned above by tommays.
