You need a 9.5 m2 sail to plane in 25 kmph. How big is the stock sail?

You can calculate the size sails you need for different wind strengths using this online sail size calculator:

If you don't want to get such a large sail, then you could consider getting a longer, narrower board, which will go faster when it's not planing.
