Low Pressure Wet bead blasting is highly specialised work. It was, I believe, originally developed for exactly this application- stripping the inside of wooden hulls.
The science is highly developed to the point of incorporating 'green-safe' chemical strippers into the slurry, as an option, and all manner of abrasives- depending on the coating which can vary from a 'bulletproof' Kevlar/glass/epoxy laminate to grandfathers latex house paint, which you most likely will peel off with your fingernails..... I'll leave that stripping part to the experts....
As others have correctly noted- you will need to sand the interior/exterior to your hearts content.... And frankly I can't think of a better tool than the Ro90... I'd also recommend a Dust Deputy cyclone; you'll really appreciate the vastly increased efficiency and you'll either save its cost in bags, or get most of your money back if/when you sell it.... :tip when sanding you'll want to 'dial down' the suction to a lower setting. Do this and you'll quickly recognise a lower setting allows the sander to cut more freely and efficiently- you'll see what I mean when you try it. A lower suction setting works much better 'all round' when connected to the sander. Higher suction pulls the sander into the surface and causes reduced efficiency.... Just don't be afraid to dial in the best suction for each different scenario....
Do it this way and with your two week work window, you should have the boat pretty well fully finished by the end of two weeks... Weather permitting lol.... :tongue
