Default RE: Early planning gear light weight sailors

Han,

I weight 65 kg (about 145 lbs) and I've done a lot of testing to find out the planing threshold (start and sustain it) of various sail/fin/board combo as follows:

6/7 knots : 10.6 sail, 70 cm race fin, formula
7 knots : 10.6 sail, 54 cm race fin, HS105
8 knots : 10.6 sail, 48 or 44 cm race fin, HS105
9 knots : 10.6 sail, 40 cm race fin, HS105
10 knots : 8.2 sail, 40 cm race fin, HS105
11 knots : 8.2 sail, 40 cm race fin, Carve 111
12 knots : 8.2 sail, 32 cm slalom fin, HS105
12 knots : 6.9 sail, 32 cm freeride fin/Carve 111 or 30 cm freeride fin/Kombat 86

From that above, you can see that the planing threshold is dependent on a number of factors such as sail size, fin size, max width & OFO width of the hull, depth of concaves, weight of the board, energy/determination/skills and weight of the rider. Some combination did work much better than other, obviously...

Cheers !
