I am at an intermediate stage I can plane use the harness tack gibe need to use footstraps and water start. I weigh 86 kilos and windsurf 4-5 times per week. I windsurf mostly on an inland lake in winds from 8-20ks. I am about to get a new board and have decided either a Go or a Futora 155ltr. would it be worth spending the extra money on a Futora or make do with a last years Go board and save £400. Steve.
