Re: First centerboard vs. rock experience
Welcome to the joys of boating .. uh .. er .. um .. maintenance. An easy fix, fortunately. Years from now you'll look back on this repair and wish they all were so easy. And yes, you likely want to tend to this repair soon as the board's core may swell up and get stuck in its trunk if left unrepaired.
You want to grind back the damaged area to the undamaged surface, opening up the cracks a bit. Wipe down the area vigorously with acetone; by the time you've mixed up some epoxy without filler the acetone will have evaporated. This is a small area, so apply the wet epoxy with a toothbrush or one inch paint brush. Then add a thickener/filler to the remaining epoxy you've mixed and apply to the wet epoxied surface. Ever done a spackle job on drywall? Sort of similar. You want to build up the area a bit beyond what you originally had before. Let it cure at least a dozen hours.
Upon your return, the epoxy should be hard. Sand smooth back to the shape you had before the impact, reinstall the board, and go sailing.
