For Segler 
Wind over 20 knots on the ocean creates big chop, a lot of turbulence in the upper 1/2m of water which seems to cap my speeds at about 21 knots (without pushing it) - even when I use my smaller 720cm2 wing.
It feels quick enough in proper swells.
Fastest ocean conditions for me are 15-18 knots of wind (with freeride/wave foils and sails).
GoPro GPS seems accurate - Suunto 5 watch shows the same speeds.
Freestyle 87L board, Phantasm PTM 830 wing
Simmer Blacktip Legacy 4m - epic sail
36" harness lines 
SSW 20-22 knots
You're really making me want to take out my little wizard 114 and my 5.0 when it's stronger than normal here.
That video really shows how the compact geometry of the board keeps changes in mast base pressure from affecting the trim very much while allowing foot pressure to trim the foil fast enough to adjust for swell.
love the GoPro GPS speedometer.... i'm not much of a speed guy, but I also don't like to get passed... I don't care what craft it is wind powered or otherwise. the speedometer is also a great way to critique your technique and a good baseline to see if you can carry more speed through turns, have good flow, and overall become a better rider. Have just started using this on wing and windsurfer.
I gather the rear footstrap is set up like that to act like a kicktail pad on a surf board?

Yes, it offers some stability/grip although a conventional centre footstrap is better in big swells.

Plus it's heaps better than stepping of the back of the board accidentaly
, Nice inovation JJ
Awesome riding as usual azymuth !. Under water turbulence is a whole new weird thing for me since I started foiling. Crazy how you can feel everything thats going on under the water. I'm on a busy recreational narrow (in most spots) lake. I have to sail perpendicular to the boat traffic. So I end up crossing the stern/prop wash from motor boats. It amazes me how violent the shudder can be. Literally like hitting solid "speed bumps". Then theres the wake surf boats and 40' sport cruisers plowing up huge swells. The I 76 really wants to follow the surface, so I force the nose down to clip the top of the first wave so I dont run out of mast length in the troughs. That works 1/2 the time. If possible, I turn up or down wind to go parallel to the wave which is the best method.

that was always my rationale for slamming the mast base back in my windfoil boards... didn't want the weight of my rig out on a long lever. i was also used to a more upright freestyle windsurfing stance to begin with too.
nice to have such clear water.... although with all the life in the water there, perhaps it's better not to be able to see it.
