Thanks for all the replies here. I removed the centerboard last night without issue (although the access hatches on the centerboard trunk seem to have been cut too high, making it difficult to remove the board bolt). I'm heading to West Marine to get supplies today and should be back in business soon.

Thanks again everyone.

Re: First centerboard vs. rock experience

There is a product called Marine Tex which is designed for underwater repairs to fiberglass as well as many other great uses aboard a boat. If you have no major water intrusion into the board, I'd just use the MT to build a patch which can be easily sanded and fared to become a perfect repair. I would liberally use acetone to remove any moisture before patching.

Re: First centerboard vs. rock experience

After sailing , fishing, and gunkholing in SW FL and the keys for several years I put a 1" X 1/4" stainless steel "sled runner" on my swing keel. Still looked pretty good after a couple years.

It is probably best to use a decent marine epoxy, not just any epoxy. There are a number of epoxies available: MAS, System 3, West System ...

For a small repair like what you are looking at I'd suggest getting a small starter kit like this one: West System Handy Repair Pack
or this slightly larger pack: West System Maxi Repair Pack

Some of the local hardware stores near me have begun to carry the West System products, so you might find these kits nearby.

West System also has a good diy instruction web page:

Re: First centerboard vs. rock experience

I remember when I paid a guy to clean my bottom. He came up and said "Theres the problem, your centerboards been snapped in two!"
$1000 dollars later I have a very robust new centerboard.

CaribDream Thanks for this. Is there a type/brand of epoxy to look for? Do I get it at a hardware store? Now the trick will be finding time - my worst enemy. I work 15 hours a day M-F and will be out of town for the next 3 weekends... Didn't take me long to mess up my relaxation for the few short hours of free time I have on weekends.

Re: First centerboard vs. rock experience

I can't add much to Michael K.'s post but I have just been doing some fairly major fiberglass deck work on my old, dinged up boat.

For a repair of such a small area you may or may not be adding fiberglass cloth. The silica thickener agent should be enough to repair the ding.
I successfully used some pieces of flashing (flat metal that is used on house roofs etc) to make a mold for a flat surface I was filling with epoxy. Making a mold that conforms to the shape of your repair should save on the amount of sanding needed to be done once the epoxy cures (1 day).
Someone else suggested they used tin foil as a release film with epoxy. I'd probably opt for the heavy duty foil over the regular stuff.
Also, some plastics, like the stuff they use to make gallon containers of milk etc., do not adhere well to epoxy and can be used to make pieces of a mold.
Welcome to the wonderful world of ... boating.

Re: First centerboard vs. rock experience

Carib, you should also check the centerboard box to make sure there is no damage there. Hard grounding puts a lot of stress on the box. You do not want a leak there. Usually fixing it is no big deal but it needs to be done sooner rather than later.
A boat without dings is a boat without character!
