That answer confuses me. On the Viper it is reported to work well, while on the Capricorn it was not judged to work well - and now both boats are said to have the same setup.
Sorry I just assumed the same guys who judged the caps boards not to work well would have fixed it. It's not a big job.
So what's the blade getting? I reckon you should put hydrofoils on it. That certainly seems fashionable at the moment.
