Could try A&J Canvas in Vanceboro NC. I believe they make them for GW. Have the boat model, year and dimenstions/pics. If the existing can be used as template, ship it to them.
once you get above 30' the GWs price seems to escalate dramatically. You have to look at other brands. There are a lot of options out there for various use cases. I love my GW buy if buying new, I'd probably be going in another direction.
Good luck, personally I couldn't waste the time to film/edit all the things I've fixed, re-engineered or replaced in my lifetime. I appreciate those that do, but only watch what I need to.
The typical spots for water getting in are leaks at the stanchions for the hardtop, windows, cup holders (drain into bilge), hatch inspection ports (replace seals, replace with screw in version vs pop-in, and re-caulk to bulkhead.
When you are done in there, get some Nautical One Extreme Mildew Remover and liberally spray everything (assuming plug is out and you have it pitched to drain out) and wash it down well with a hose. The area will clean up nice and all mildew will be gone.
Saw the new model at the show today. $900K show price. Overall a very nice boat. Cabin is a big step up and aft birth area could sleep 3 if needed pretty comfortably. Microwave hidden in a cabinet which gave a clean look. Plenty of room at the helm for the large electronics. I'd say the...
Smaller boats I get it. All are tradeoffs. In a big boat, I think you need to have a design that isn't overly cramped in the helm. I'm sure it doesn't matter much in a 35' boat if center or starboard helm. The 33 is just too darn tight just like the 282 was IMHO.
I'd replace them just because they scream 1970. If the guy knows what he is doing, it really shouldn't be an issue. Far better than wood and the associated maintenance.
