Wood Vs. Foam Bd. for Floors

As I embark on the floor replacement of an 85 2001, from previous posts, I see I have a decision to make.
I only found a thread on this choice as it relates to the stringers..
I have one project under my belt, I replaced the wood floor of my 85 AM skier, with another wood floor, per soaking and coating both sides with epoxy.
Foam board is appealing to me as it would be a lighter finish product, it’s my sisters boat, and she is a skier, so a lighter boat is a big advantage, being smaller wake.
I would only presume foam is attached to the stringers with adhesive, I think it’s 5200 by 3M
If this is correct, would it simply get glassed to the hull, with woven FG, and laminated with the same, as well as stranded material ?

Just my opinion but when I read about stringer and deck rebuilding using all the new materials Coosa,HDPE ,PVC ect   The original materials were nothing special uncoated and still lasted 25-35 years. Now the boat is 25 plus years old its very doubtful it will be around in another 30 years . If you choose good wood and coat it with CPES I think it will last 30-40 years. I question weather the added expense is worth it.

Interesting product, looks like the Gatorplast could be a good choice, just talked to sis, it’s her boat, and she would like to try and keep the weight at a minimum, and coast is not an issue either..
Have you ever used this defore ?

I just bought an 85 SN 2001 - and am determining my to-do list of items I need to do right away and then those that I need to be planning down the road..


I've only had my boat in the water one time and it seems to handle well - but I am concerned about the integrity of the stringers.. I've seen some of the posts on what to look for - but any advice on how long one can prolong a rebuild.. aka - what's the general rule of diving into so much work..

Is there any temporary fix one can do to "buy some time" like drilling holes along the stringers and using a resin of some sort to fill in any voids...


Perhaps silly questions from a newbie...
