Floor Repair Questions

[apneadreams]

Hey everybody, I want to take a moment to say that I'm the latest SeaCraft fan on board. Briefly a little history...Cruising craigslist, I came across a boat and trailer for sale for best offer and with it came some restoration materials, so I sent a message offering $500 and he accepted the offer so off I went to inspect this rig...It was love at 1st sight, beautiful lines and a smart cockpit set up...with the deal came 2 rolls (40-50yds)of fiberglass mat as well as the original CC as well as One he put together (that needs to be fiberglassed), a ton of mixing cups and (2) 4'x8' high density foam board (not coosa)??? for the floor...Too make a long story short this guy has had alot of exp. rebuilding boats and had already done alot of work on this one...transom replaced and increased from 20" to 25", rub rail repaired and flared out abit with mahogany, strigers reworked and raised... now I have been looking over the posts on the website and have gained ALOT of great info. on how to proceed with this rebuild.... NOW TO THE POINT......for the floor he threw in 2 4'x8' high density foam boards...it's not coosa, and looks like hard,rigged styro foam that is yellow...The Question is, what is this stuff and if I use it on the floor with it sandwiched with fiberglass on both sides, will it have enough strength for me to attach a T-Top to it? Any help will be appreciated...

P.S. The boat is a 1971 20' seacraft and i will post some pics when it stops raining... Thanks again.

WOW! It sounds like that guy saved you alot of work!

Corecell is kind of yellow, but it could be anything.


Pretty sure that everyone is going to tell you to use marine plywood where you want to attach things, predrill the holes over-sized, fill with resin, re-drill to avoid rot, and use foam everywhere else, although I have heard of people through bolting stuff as an alternative if you have access(foam does not hold screws).

Two words for you Sir........you dog!!!!

As far as the t-top. Use the marine plywood where the console and T-top will sit, 2" inside and go out 6" to 8" to each side and a then a couple of inches past the front and back. Glass this in first and the foam around it. So you would cut two pieces of plywood 10" x 48" or so. In most all cases T-tops are mounted as close to the sides of the console as possible and you will also be mounting the console into wood. Heck....If you have room double the depth of the wood in order to use longer screws if you want. Just an idea.

Thanks for the replies guys...I will be using marine ply for the whole deck area since there won't be a whole lot of extra weight added...BTY, how did you get the pic to come up
IslandTrader?...Thanks again, Steve

how did you get the pic to come up

Go to your PB picture. Click on direct link. It should copy this link. Then come back to CSC and in your message area click on image. Then when the box comes up paste (ctrl v)and OK it. Then the image should show up in your post.
