Fiberglass Question

I have a Lagoon 500 and I cracked my starboard keel pretty good on rock in Belize. No leakage or anything, but the forward lower corner is smashed in a bit and then there is about a foot long crack that goes up the keel as well. The fiberglass is definitely exposed to seawater.

My question is, does anyone have any idea what kind of rate of seepage I will get into that fiberglass? The closest place I get it hauled out is in Mexico, but I can't take it up there anytime soon. I am wondering how long I can leave it before the water really starts working deep into the glass.

Any comments or opinions would be helpful.

Well, and what is inside of the keel? If it is solid, no problem.

It's a catamaran and just has those little stubby keels. As far as I know they are glass the whole way through.

I doubt that the mini keels on the Lagoon 500 are "fibre glass all the way through"
Not sure where you are, but is it possible to beach the cat so that you can really examine the extent of the damage, photos etc.
Do you have any repair materials on board eg. epoxy, glass cloth etc.
I am not sure how the these keels are constructed, but I am pretty sure that they a sandwich core of balsa. Which when exposed may suck up sea water.

If you have epoxy for emergency repairs aboard, close the cracks with it until next haul-out. If you don't have this aboard, buy it in supermarkets or hardware stores. I've found it everywhere around the Caribbean but haven't been in Belize yet. The epoxy in two small cans (partA & B) is called T9 or P9 or something like that. The epoxy sticks are good too and available from the same brand. You can use that under water.
