i taught a guy to sail yesterday on a starboard start, first time he had ever sailed, he was 100kg, after one lesson he can sail in a straight line confidently, 100m without a fall and at the end of the lesson pulled 3 tacks perfectly. he is going to buy a board and has already ruled out the start, and prob go to a much smaller board 140ish litre.
my point is once he realised if he don't stomp all over the board and be gentle moving around the board i got more and more stable and he was cumfy enough to progress to something less stable, being smaller and less of a bigginer board. and this guys been sailing once.
Modern boards are exellent for versitility, if you can demo a board or borrow one around the size you are think even a little smaller, jump on the oppertunity and figure it out from there.
i just bought a smaller more full on wave board than i have been riding in the past (quatro 84 wave "08",


) the board is dificult to ride in the lighter stuff, don't plane real well, but after 3 sails, even under powered i'm progressing with my wave sailing and by next summer should be ripping harder than i ever have. if i had stayed with my old board or not went out on a limb with buying this board, i would not have progressed with my sailing, and i think that is the main reason in buying a new board, to progress..
