I remember the time 6.6 size sail was big sail!! LOL.....
Now i have a 9.5 but i really do not want to bother with anything bigger.And my fomraul was the oldest original 155 ( i wrote a story about sailing it, starboard liked it and it ended up on the forum year back! my only claim to windsurf fame)
Not that i dont think it ( a larger sail) wont work,
just that i do have other things to do.
like: fix stuff at home, my spend time with my wind widow ( my wife) , and at the camp, vehicle maintenance other ( gasp god fobid I admit) hobbies!
