Hole in Hull????

We just put our Prostar 190 back in the water after the long winter. We were going to wash and wax the trailer when we noticed one of the bolts sticking out of the bunk. I didn't know if it vibrated up on the way back to the house...so I checked the boat...just to make sure. Well....we have a nice hole in the hull! Its about the size of a quarter maybe a half dollar. How should we fix it?

Products to use? Its on the lift now.

Thanks for your help in advance.

Greg

I wouldn't touch it... take it to a glass shop to have it fixed.

unless you are experienced with glass it's always been best suggested to let a glass shop fix it right.

Are you sure you didn't hit something in the water (hint-insurance will cover the repair bill)? If it's just a gouge, you could do your own gelcoat fix. But if it's all the way through, w/o question I would call insurance and let the pros fix it.

I could see a bunk bolt putting a good scuff, scratch into the 'glass, but a hole? Like someone took the nut off and smacked it with a hammer into the hull?
Either way, bottom of the boat is a good place to practice your repair skillz since cosmetically, noone will see it. If it's all the way thru and you can see it from the inside (probably not b/c the bunks line up with the stringers I think??), put a piece of backing over it and stuff it full of resin coated fiberglass. Make sure it's pretty solid resin/glass all the way to the surface either way.
Then grind down a nice square patch of gel around the repair, with sharp square edges, at least 1/16" deep, up to 1/8".
Order up some gel coat paste from Spectrum color, or a small can of matching gel if your boat is too old to get a tube of the gel paste.
Follow the gelcoat instructions, there are several threads on here about it and on Spectrum's site.
Be proud of your handywork and if it isn't perfect, at least it's on the bottom under the bunk. Noone except a wayward scuba diver could ever see it!
Other than basic hand tools, a dremel or small grinder and polisher are the only power tools you'd need.

I'm no expert but I would tend to agree with Thrall on an attempt to fix it.

I just spent this last weekend doing a fiberglass repair on my trailer fender and am quite impressed actually. I've never worked with fiberglass but it does dry hard and very solid. From my laymans point of view, I would do some light sanding on both sides so that the fiber/resin can get a good bond and then go to town.

I know that they make a "gorilla hair" type of fiberglass mixture which could work pretty good for you. As long as you don't disturb too much of the surrounding area, I'd give it a shot. If not, bring it to a fiberglass shop.

I used a wire wheel brush to get to a clean, bondable surface. Once dry (like 1-2 hours), I took the wire wheel to get it roughly to the shape I needed. Then hit it with some sand paper.

Again, I'm no expert and have only done fiberglass once!

Good luck.
