RE: Mistral Naish 8'11 - any experiences?
While I can't talk from experience actually sailing the board, it comes before width started playing an influenial role in shorter boards. Because of its narrower planform, I would really question the viabiltiy of 8.0 sai, even at your weight. My guess of the board's sail size limit is probably 7.0-7.2, and that might be on the generous side. However, sails in the 6.5-6.8 range might be a more suitable conservative upper limit to consider. If I recollect correctly, the board represented Mistral/Naish's largest light wind wave design of the time, but with a rockerline that tended to be bit flatter than a pure wave board to give it some speed and blasting ability. I hope this helps some. Maybe those who spent some time with the board can offer a more specific background about the board.
