Drainage - My 1976 MA drains go straight down through the floor (like the SF) . . . My feet will get wet if stand in the corner and when the plugs are out. I just run with plugs in which is no big deal. I also have a center drain (which looks like it was added later - regular 1" drain hole) in the back channel which drains into the bilge and any water that splashes into the cockpit goes down can drain down into the bilge and get pumped out the automatic bilge pump.

As far as soft spots go . . . I would do spot repairs on the deck and just recore the areas that have gone bad. There's no sense in ripping up the floor that is 90% solid.

Just cut the top skin off with a circular saw (set to less 1/4") replace the rotten core (balsa) . . . clean up the underside of the skin and glass the skin back on the new core.
