how about seadek? I recently did my cruiser in it and it is soft, stain proof, and so far holding up (2 years). You can buy it in sheets to make it one piece

They will even template and do custom logo's anywhere on the boat. My friend has this on his swim platform of the scarab, just bad azz. I have been considering doing the floor of my fountain.

I looked at Lonseal, but after receiving samples, I knew it was too hard for long term standing. The lighter stuff also seems to look dirty over time. I ended up using this PVC flooring called Deckadence and couldn't be happier. It has a nice cushioned backing and doesn't matter if it gets wet. Best of all, it doesn't show every little spec of lint or dirt like my old navy carpeting. I used the carpet as a template and simply cut it with a scissors, then added snaps.

Plum crazy what did that set ya back??

IIRC, it was ~$400. But, I had enough to do under the rear seat and the head as well.

I also did the dekadence after looking at seadek and lonseal. I liked being able to easily remove it to clean the boat or it if needed and it is extremely comfortable for standing on and doesn't get overly hot in the sun. Water also runs right through it so it doesn't hold moisture. I bought a 6'x6' piece and I think it was around $350. Great product though. You can go to their website and they will send you free samples.
