These are presumably permanent (ie non-removable) floor boards? It's interesting (well, it interests me!) that the Trouper 12 was designed with removable floor boards which have disappeared during design evolution. Much better without, I'd say. The T12's bottom is wide and fairly flat so, as well as glass-clothing the bottom outside (with 200 gm cloth), i've done the same inside but with 100 gm cloth. My thinking was influenced by the relatively recent acquisition of a largish dog (a retrievador) who will be additional crew in due course, and I thought some anti-scrabble protection might be in order (hence also two-pack paint - fairly soon now). Encouraged by how well it's turned out, I plan to do the decks as well: that's a job just coming up.
