Re: hull reinforcement.

There is a section in "This Old Boat" by Don Casey on how to reinforce the hull of an older boat by adding stringers and tabbing the bulkheads, along with a vast amount of other information. You might want to consult first with a naval architect/marine surveyor/fiberglass repair specialist on the need/desirability of reinforcing your particular boat. Bristols have a good reputation as well-built and well-designed boats.

Re: hull reinforcement.

I re-enforced my old hull by glassing in ribs and adding 5 coats of west system outside and coated the bilge with thick bi axial cloth and west system.

Re: hull reinforcement.

Unless you put glass on the outside, those extra coats of epoxy did nothing but add weight. Epoxy by itself isn't a strong medium, it's a glue. It's no different than coating the exterior with five coats of Titebond. The glass/epoxy in the bilge was right, though it's necessary to have a proper bonding surface, otherwise you've just created a male plug....

Re: hull reinforcement.

Well, I took all the gel coat off the outside and did a big blister job, then came back in with the 5 coats of west with alum. powder for my barrier coat making it very strong as in hard and water tight. That was in 1994 and I haven't had a blister since, it's still very hard. I did a very good job prepping the bilge and added the Bi ax because my center board knocked a crack in the well. That was when I was 200 miles off shore and it caused a nice steady leak. Which I patched with a chop stick and a sock. So I re-enforced that. And the ribs that I glassed in have def. added some strength. All in all boat hull is stronger, and more impervious to knocks and bumps, swell beatings because of the work I've done.

Re: hull reinforcement.

Good. The aluminum powder added to the epoxy made a composite. Now you've got something useful. Your original post said nothing about the gelcoat removal nor the aluminum, hence the confusion.

Re: hull reinforcement.

The older Bristols had a pretty solid hull, so you might reconsider the additional work and expense to accomplish little. Chuck

That was my first thought, too. Why? Bristols are well-built boats.

Re: hull reinforcement.

A solid fiberglass hull on an old Bristol that need reinforcment? That's kinda scary.

Buttttt, as posted, Don Casey wrote the book. Lotsa pix and illustrations too!

Good luck!!!
