These boats can race boat for boat, by adding a spin to the Hobie. I can beat some of them and some of them beat me. I'll presume it is sailing skill.
My future wife has no problem with the spin, but we trade off on long runs. Ratchetting blocks are key.
if the Hobies and the inters are raced boat for boat then there is a larger class, and everyone agrees that racing boat for boat is better than racing numbers, (unless the numbers are really in your favor and you do not wish to improve your sailing skill).
my 2 cents. where we sail it is getting harder to attract sailors to race. anything that makes a larger class is good.
