For what it is worth.

I just came back from the Paris boat show and the new 16 ft Ventilo Zipo (said to be designed for the F16) has assymmetric daggerboards. The guy at the stand did advice to raise the one on luff when racing.

Here I some pictures of this new design and will post them shortly on a website. The Zipo has a new planing hull design and I have pictures of that too.
