Here is the interior of my Sea Nymph 171 shortly after I finished the rehab about 3 years ago. I dumped a couple coffees in it and burned the carpet with a bad wire from a bait tank. I finally got around to buying the Nautolex vinyl to replace it and started tearing the old stuff out today.The floor was a little springy right in the area of the seat base, so a few months ago I cut a piece out and poured some foam, then put the seat base in to cover the hole. I don't like the seat base there so it will not go back in. I saved the cutout piece and put it back in today.

Here is the deck with the carpet out and just the left over hole from the foam pour. I cut two more holes today and poured more foam to finally get the solid floor back there I need. There is a 24 inch gap in the crossbeams there that made that area springy when you walked, the rest of the floor with 12 inch centers is solid as a .rock. The original foam made the floor solid there and the pool noodles were not doing the job.I poured new 3 lb. foam and now it's all solid. I used a series of small pours and when I knew the next one would hit the bottom of the deck, I poured a double portion and then I put the cutouts back in and screwed them down with a piece of 1X6. The result is a solid almost completely flush floor where the holes were, with the cutouts glued in solid by the foam coming up against them from the bottom. I will fill the gaps with an epoxy anchoring compound I have. The compound is designed to secure anchors in concrete. I got it from my work, because it had expired in May and they won't use it now. It is perfect for filling these gaps.

Third cap curing.

All three foam holes with the cutouts back in and solid.

I couldn't help myself I had to open the vinyl and roll it out a little to see how the colors looked. It is lighter than it appears in the pic, I hope it looks good with the gray carpet.
I'll let everything sit and cure for a few days, the deck looks good after three years. I will probably hit the deck with a belt sander to make sure everything is smooth and level, hit the cutouts with a fresh coat of sealer, then start the vinyl install.
I also intend to pull the batteries and gas tank out of the stern and paint that whole area with some deck paint before I put anything back in.
