Dealing with the Deck After the Teak Comes Off !

[boatsmith]

One thing you can do for an older teak deck that has leaks and you don't want to spend the money to remove and paint or replace it is to paint the deck with Sno-Cote.This is a white elastomeric paint designed for the roofs of mobile homes and the like. It is inexpensive and will seal up any leaks and provide good nonskid qualities. You can also tint it to a moondust color.

This is what I'd do:
Assuming that once you have the teak off that the core is OK
And assuming you don't want teak back on

1) Strip off the gel coat & fill any screw holes, sand off hard for a key
2) Glue some rubber non-slip flooring or anything else with a tread pattern onto a sheet of ply - this is your mould.
3) Make up a number of fibreglass sheets from your mould
4) Cutout sheets to the shape of the decks using templates
5) use resin to stick them to the decks

the formosa 51s should be wood (ply) with teak over. there are many screw holes. the ply will be rotted out. the deck must be replaced --some after 1980 had frp decks with screw holes. this isnt just formosas.
teak decks are not evil. the installers who placed the 900 bazigillion screws were evil. teak is the best nonskid in the world. go figger. flush with sea water every day and you have good decking. forget and you have not got anything decent. must be done every day. the quality of teakwood decks is the responsibility of the owner.
formosa owners group on yahoo changed name to leaky teaky yacht club in yahoo groups. there are folks who did their deck replacement with fotos. formosa 51 owners group is good also. these are excellent cruising boats after the deck work is done.

oif this is a pre 1980 formosa--you will have to find someone who knows what he is doing to repair them or go to leaky teaky yacht club and research the pictures and talk with some of the guys and see what they have to say. mine only need a bit of ply ripped out from underside and more ply inserted in the place of the old dead ply. ..with a bit extra epoxy and glass to outer surfacing under the sprit.
these are not cored decks until after 1980. until 1980 were plywood with fiberglass overlay, and that was AFTER the teak was removed.
