Luiz: Most of us never heard the details about Hydroptere' and stability issues. I heard that they broke several main lifting foils. Anything you could add would be useful. Hydrotere' did look WAY high out of the water when I saw pix of it foiling.
Alex Shafer and Nigel Pitt are sailing a Reynolds 33 on the west coast last weekend? The one with foils?
