While I sold my wooden-hulled 1972 GB42 CALYPSO in Jun 2015 after 29 years of ownership, I still hear from the current owner from time to time. We recently talked about his desire to cover the decks with fiberglass rather than fight the battle of curing recent deck leaks. I reflected that removing the existing sound deck would negatively affect the overall strength of the hull girder. He called back the other day and told me that he had elected to glue and screw 1/4-inch marine plywood to the decks after removing the cabin-to-deck quarter-round trim. The inboard surface of the bulwark and the cabin sides were sanded up about two inches before he applied a couple of layers of fiberglass ensuring attachment up the sides onto the bared wood to prevent water from finding its way underneath. On top of this he applied a white polyaspartic resin (used in tank linings - he is in the refinery business). He describes it as being similar to sprayed in truck bed liner. For the actual walking surface he plans to apply a teak-colored material which is slightly rubbery and easy on the feet. He said he and his hired hand could have done everything up to laying the final walkway material down in a week had they experienced that much continuous good weather there in Galveston. As it happened, he says it took three weeks, even though the boat is kept in a covered slip. I think he is into the project by about a couple thousand bucks in material. Note that this Grand Banks is a very different animal from the fiberglass GB Rudy worked on and described here where he removed the teak down to a fiberglass structure. On that boat, the teak had been laid down on top of structure while on a wooden boat, the decking was part of the structure. In an interesting side note, the four fuel tank fills had to be removed during the process. Once the screws securing them to the deck were removed and the deck seal was broken, they each lifted out of the flexible hose connecting to the tank tops without much resistance. I assume the virtually unreachable hose clamps ware no longer doing their jobs. Rich Gano FROLIC 2005 Mainship 30 Pilot II Panama City, FL

This method of COVERING teak decks was well-discussed a number of years ago on the list. Seems to be very successful and those who applied it liked the appearance. It was described and referred to as "truck bed liner" (definitely not the various types of paints that some people have used) and it seems to be some sort of "plastic-based" material. Former list member Charles Cullotta was one of the proponents, and the several times I saw his boat I was impressed with the appearance of the decks. I'm sure there's a lot of data in the archives about using "truck bed liner" over teak decks. Saves a lot of work, but I think the decks need to be sanded relatively smooth and missing bungs replaced before applying. As I recall, Charles ran his liner about 3-4" up the side of the cabin and outboard side on either side of the deck. <><><><><><><><><><><><>Mozilla Thunderbird<><><><><><><><><><> Bob McLeran and Judy Young Manatee Cove Marina MV Sanderling Patrick Air Force Base DeFever 41 Trawler Melbourne, Florida Blog: http://mvsanderling.net/Blog Web: http://cruising.mvsanderling.net/ On 4/8/2018 11:37 AM, Rich Gano via Trawlers-and-Trawlering wrote: > On > top of this he applied a white polyaspartic resin (used in tank linings - he > is in the refinery business).
