Centerboards for Gemini 3200

[TwoCan360]

Attention on Deck.
I have am Gemini 3200 and worms have gotten to the centerboards.
I am building new ones and need to know if they are symmetrical or asymmetrical. My current boards are distorted due to swelling. And the 3200 boards are different from the MC105s.
Thanks for any help out there.

A bit late I'm sure but the 3000, 3200, 3400 and early 105's had symmetrical boards. Much more sensible on a cruising cat. Assymetric boards only make sense on actively sailed boats such as racing boats.

As Clockwork says, cruising boats can't really use assymetric boards. You have to retract the windward one by pulling it up after every tack like the AC45 cats did. So your boards should be symmetrical, even if they were designed to be assymetric for some strange reason.

My two cents - get your diving gear on, our with the boat on the hard, really check for the minimum width of the case. I have had issues with building boards 1 or 2 mm wider than they should have been. It can be very hard after you add some filler to smooth out the weave and then paint the thing. It is always easier to build the boards first and then the cases. So err on the side of caution and leave 5mm at least for glass, filler and paint.

I don't like using ply for boards as half the grain runs in the wrong direction. If you can get ply with only one orientation of veneer, it is called bendy ply in Aust, then that is okay, but I like cedar better.
