i use 7.6 m?? and weigh almost 90 kg :d but i only have good planning whne i hit 4.5 bft or more ... it's why i'm looking for larger rigs but i'm a cheapscape

anyway, My advice stays the same, get the carve, great boards, want to buy one myself (the 111) and start investing in big sails like Roger suggests and just have a blast really!
