I notice that i the boatyard here in Port Townsend, the sanders that
get used are the big Fein (see Amazon) random orbitals with a powerful
vacuum attached. Since sanding bottom paint can make you pretty dang
sick, not to mention most other living things, the vacuum, which
claims to capture 98% of the dust, is a real advantage.
