RE: new vs. old slalom shapes
Is it fair to say that the new wide short boards plane quicker and accelerate faster especially in moderate slalom conditions (7m sails) than the older narrow long boards?
But that the top end speed of the older shapes is greater?
So in a slalom race(again with 7m sails) with many jibes a wider board could easily win due to its ability to carry speed through the jibes and accelerate quickly.
In hi wind slalom conditions(5.8 sails) the advantage of the wider board diminishes as control in the choppy conditiond suits the narrower board and speed through the jibes is less of a problem for the narrow board.
