RE: Carve 133 vs GO 165: HELP!
Where did you see that the shape of the GO 129 and the Carve 133 are "identical"?
Here's the "spec's" from the products page:
Carve 133 133 252 71.5 46.8 8.05 7.7 5.4-9.0
GO 129 129 251 72.0 47.0 TBA 9.9 4.9-9.0
I would say that they may be "similar" but pure "outline dimensions" do not tell the entire story here.
The GO most likely has a more "wide board" rockerline where you will find the Carve has a more "fast freeride" rockerline.
While both board suggest your 9.0 m2 will work, at 83 Kg. I suspect you won't get planing very early on either of these boards. Maybe in 12 knots, but your weight is a big factor here and that would push the planing threshold up a knot or 2.
The GO 129 will most likely plane a little earlier (due to the rockerline) but it won't be a loose and turny as the Carve and won't be as easy to jibe.
I'd strongly suggest you try to "test drive" both of these boards before you buy one of them if that's at all possible.
Why do you feel the 3 footstrap positons on the GO 129 would be "more comfortable". The board will only reach it's full perfomance with the footstraps all the way back and outboard.
Th Carve has both inboard and outboard FS positions as well as some small adjustment front to back, so you have almost the same number of options with the Carve.
I think it's going to take pretty much 11-12 knots to get your 9.0 m2 and 83 kg. sailor planing.
Can you keep your GO 165 for light winds, and get a Carve 133 or 122 for stronger winds?
Hope this helps,
