WOW! This thing is great!
I finally got a chance to try the board out, but only if flat water in the sound in OBX. Goes upwind like crazy.
In the morning it was a gusty 12-14 knots on my 11m Rebel and was going upwind no problem. Others were staying upwind with 14m kites and twintips. My buddy who is about the same size as me (165 lbs) was on a twintip and 11m and said he had to struggle to stay upwind through the lulls.
Only downside I see is that the fins are super cheap. I sunk a bit during a tack in lighter wind, just barely hit the bottom and one of the rear fins completely snapped off at the base! Board rides pretty well with 3 fins though
Luckily better FCS fins are cheap.
Later in the day it picked up to about 18 knots so I went out on my 11m Rebel and smaller twintip. At the end of the day I decided to give the (now 3 finned) SP another try, but thought it would be awkward to ride such a big board when I was getting powered on my 11m. This board was a blast in powered conditions! It just flies up wind with great speed. I was able to ride upwind from kitty hawk kites in Rodanthe up to the Real slick in only about 20 minutes of riding (1.5 miles straightline distance. Wind was at 45 degrees to the land, side onshore.
Can't wait to try it in waves.
