> never about owning a 3.3 or even 3.7.
I've a got 3.7, use it a few times a year, well worth it

. Next size up is 4.2 and that gap works well, 4.0 down to 3.2 is a stretch I think. 3.5?
Depending what you weigh, when it's that windy, if your board is floaty for you it is not going to want to slow down much though, you definitely want something with litres < your weight for it all to work together.
