I have filled the holes on both the rudders and daggers and made new holes on the top of the daggerboards and covered them with tape.

I never understood why Bimare put the holes at the bottom of the foil. If they want a pressure release hole it should be above the waterline so it wont leak. And the hole is so small that getting water out is practically impossible. WF used to suck the water out, which is something I've tried and really dont recommend, salt water plus vinylester is quite possible the most horrible taste on earth.

packing tape works to cover the hole pretty well, or if its above the water line colored electrical tape works good. too.

If anyone out there has a broken Bimare HT foil - dagger or rudder or both, or ever breaks one, please either send it to me or take pictures, I'd love to see where the are hollow vs solid.
