I just did a complete gut of my boat. I then put in new foam, main floor, front and rear casting decks with chairs.
It took about 30 hrs but the boat is awesome i had it out on monday for a test run.
It cost about $800 and i already had the chairs.
The new vinyl from homedepot is real nice $250 for glue and 20' piece. I will get pics when i get a chance.
