Way too small a suggested sail IMHO:

I'm using powerwave sails for my 65 kg as follows:
20-25 knots : 5.4 m2
25-30 knots : 4.7 m2
30-35 knots : 4.2 m2
35-40 knots : 3.6 m2
40-45 knots : 3.3 m2
45+ knots : 3.0 m2

Bear in mind that the range of a full-on cambered racing sail is larger than that of a no-cam wave sail.

Cheers !
