HMT2 and I both did our boats interior floors and sourced Houston hardwood For teak and holly. You can also check Kemah hardware. Not too difficult to do. Time consuming to remove cabinetry from wooden cleats that are used as tie down connections. Will defInitely need a small knobby Phillips head screwdriver To reach into hard to get to places. You can use the existing floors as templates when cutting teak/Holly plywood.
if OP is unable to locally source teak/holly plywood Locally in Navarre, you could use marine grade plywood and purchase over the internet teak/holly laminate similar to the old Formica countertops and glue this down to the plywood. Any question, like HMT2 send a PM.
