Restoring 1988 Doral Bowrider

[Lukey220]

Hey everyone!! Last year I took on the project of redoing the stringers in my Doral Spirit. I’ve grinded the old ones out and bedded in the new stringers , now I’m at the point of glassing.

The stringers are 3/4x5.5” plywood, with two bulkheads along the way and im using polyester resin.

My question is how much glass to use and if I need to go over the whole stringer with each layer, or if I can do CSM to start over the whole stringer and onto hull, then 16oz Biax over whole stringer and finish with 24 oz Roven that just goes 6 inches onto hull and half way up the stringer, that way I don’t need to try and bend the 24oz over the top of the board.

Any help is greatly appreciated!

opinions will vary, but the general consensus on this board is to start with CSM, and then 2 layers of 1708 over that, going about 6" out from the stringers on either side (at least).

if you are using 3/4 ply for the stringers, you will play hell getting any of that to wrap up and over the stringers and stay down. Likely you will need to cap in several layups each only having either an inside corner (at the hull) or a couple of outside corners going over the top. Either way, the heavier the cloth, the less likely it is to bend and lay down. 1708 does a pretty good job of it though

keep in mind the manufacturer got away with chopper gun spray fiberglass, so anything more than that is likely "good" but not as good as it could be.

Thanks for the reply!!! Splitting it up is probably the best idea like you said. I’ll keep that in mind!

if you have any questions, or need a bit of a tutorial, there are a LOT of threads in this forum here that have done just what you are about to do. You are not alone!!! good luck with the rebuild. It will be worth it in the end, and if you do it right, better than new

Thanks so much!! Been taking pictures the whole way hoping to post a full restoration thread when I’m all wrapped up. Learned a lot just by lurking this forum
