That nasty crack
Here are a couple of photos of the crack in the starboard side of Black Magic. I should have put a ruler next to the crack for scale; both the horizontal and vertical parts are about three inches long. It's actually a crack in a patch on a patch that might be placed over yet another patch. I suspect previous owners of the boat have just been stopping leaks without looking at whatever the underlying cause of the leak is. I don't think it's hugely serious, but I would like to fix it in a more permanent way than previous owners have.
Since it's below the waterline, I haven't been able to see whether there's some external evidence of the crack; one idea we had was to use a halyard to heel the boat over and see whether we can get this side of the boat raised enough to see whether there's a crack or anything. I'd also like input from other Etchells people -- is this sort of crack common in an Etchells (especially one 33 years old), and if so, what is the usual way of dealing with it (besides piling patch upon patch)?
