I'v just got a iS144 to replace my old F159. I'll use it with a 9m & 11m in summer breezes. Talking to the UKWA guys on the amature UK race circuit, they all say that the 2007 (narrower) iS133 only looses about 3 or 4 knots in wind minimum C/W formula. As Pfaffi says, up/down wind wont be as good, but should still be OK.

Cheers
