Deterioration around thru hull

I went and looked at a westsail the other day and was concerned when I noticed decay around a thru hull fitting. It seems to be a pretty deep gap at the area with the blue paint about 1/4 inch away from the fitting itself. Although this is a non cored hull, is that a serious issue or could it just be patched?

Hey Livin hows it going!

Its not a deal breaker if its an isolated thing..

If it were me Id pull the through hull and grind back to good glass and rebuild it up...Install a proper backing plate and bolted flange seacock she will be better then new.

Its going good,back on the prowl for another boat!

The westsail had a fairly recent survey and it seemed pretty good. Its just that one thru hull that has that problem but considering how thick the westsails hulls are I am hoping its not too serious.

Hey LOD, good to hear from you!

From your description, that doesn't sound too serious -- but would definitely need attention/repair. Also, it might be wise to seek a professional opinion (marine surveyor) before purchasing.

Which model Westsail is that you're looking at?

Its a factory finished 28. It needs a little love but it isn't in too bad of shape.

You might consider relocating the thru-hull (if you can) and grinding out, then patching the bad spot. That way you won't have to worry about the thru-hull being on a slightly weaken spot. An epoxy-glass patch, properly done, should be plenty strong. But, by moving the thru-hull to a "virgin" area, you can be doubly sure that the patch won't have any added stresses on it.

Regardless of whether you move the through-hull and patch the old spot or patch the old spot and keep the through hull there, I would highly recommend you follow Maine Sail's tutorial on installing through-hulls and use a decent fiberglass backing block, or one made of G10 garolite if you don't want to make up a backing block yourself. Bed the backing block in thickened epoxy so that it spreads the loads onto the hull evenly.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Doesn't sound too bad, maine sail's tutorial seems pretty helpful. As always thanks for the info!

Stillraining, I ended up selling the contessa to a local at the yard after I moved and was going to school and working. (I had started realizing that I may had bitten off more then I could chew with that project) But that way I was able to save up a little more money and now I can get a little less of a project.
