RE: wave boards?
I just received my K79 technora and was able to try it with a 6m2 sail, a Naish AMP. I weight 63 kgs, sailed on a lake with choppy conditions with an irregular wind up to 15 kts, with the freeride settings. The board floats well for me, I pull up the sail without sinking, but it is true that the fin is a little small. You just need to pay attention and not put too much pressure on it. I will buy another fin. I am thinking of a select FSW 27 or 29 cm.
