if you are going longboard light wind wavesailing don't bother with anything over 5.5. I'd recommend a 5.0, even in about 5 knots.
I seriously don't think a 5.0 will get me out in 5 knots. Because of the Kona's nose volume it won't take much to change it's direction as it will bob up if I don't have enough power, I'm not talking about planing power but punching power (momentum) to go over or through white water. As I already have a 5.0 Gaastra Wavefoil I will test your theory, just have to get out and try.
What happens when you drop in on the wave is your apparent wind increases and swings forward, so if your sheeted out even slightly you get backwinded and fall off. The bigger the sail the worse this happens.
Smaller sails make it easier to uphaul in the break and get away before the next wave in the set.
I experienced this a couple of times but blamed it on me pointing too high on a wave due to the board/wave relationship...same thing? I've got a great story to tell but will save it for another time..."phew" says the masses.

I've been aware of the other obvious problems using too big a sail mainly the longer boom and deeper foot getting caught on a wave but was not aware that the larger the sail is the more a problem apparent wind becomes. So thanks for that.
There are 2 guys that have been influencing me in light wind longboard wavesailing, these guys are Jeff Henderson from Maui Hotsails and John Ingebritsen (Kona rider/demonstrator), they use 7.0 sails...both Maui Super Freaks. From the vids seen they are riding in small waves and in wind around max 10 knots, my preferred conditions at the moment. Because of the small size waves perhaps this has not given them too much of a backwinding problem?
