As far as making your boat comfortable and homey, I rebuilt my entire galley. I used 3/4 hardwood plywood to make my cabinets. I have 11 lineal feet of counter tops now. I was also able to free up some extra storage space by adding a extra door. I also re did all my cushions. Used better foam. On my bulkhead walls leading to the V berth, I covered the walls with "Bellawood" 3/8 x 3 solid prefinished real wood flooring. I used Mahoagany because my boat has a lot of that wood already in it. Teak is available and the wood it's self isn't very heavy, so I added very little extra weight to the boat with a finish, I would never be able to achieve.
