I was always of the opinion that the best thing that happened to skiing is snowboarding.

I now have one pair of K2 Obsethed and that's it (well to be honest three pairs of the same ski - rock version, nice non scratched version and the version with dedicated backcountry bindings). Nothing else.

Looking on this inflatable bladder I almost want to say that may be the best thing that happened to windsurfing is... well this thing that they inflate and send into the air... Smile still dont want to say this name out load...

what regular sail ( curved plate profile ) offers , 15 MPH wind range at it's best?

I'm not a sail expert by any means, but from my experience you can't put a fixed number on all sail ranges. For me, as sails get smaller their range gets smaller & as sails get bigger their range gets bigger. So my 9.2 has a bigger range than 15 mph & my 5.0 a smaller range than 15 mph.

This was one of my concerns in high wind sailing. I teach "Never ever, ever, ever, ever let go of your boom" but it happens. Separation from your kit in high winds could be a potential disaster as the wind would blow your kit away since the sail will not sink. It also sounds like your sail doesn't de-power. I'd hate to be forced to only jibe in high, off shore winds.

Than they go back to get their 6 and 7. By the time they get back on the water wind is back too. For them it's time to go and get their smaller sail again.

We obviously sail in different locations. I don't experienced such wind variations where I sail but I have experienced this at the Gorge. Also, much of my sailing is a quick 1-1.5 hours after work on the way home with rigging time about 1/6th what I saw in your video. I don't use race sails for quick freeriding or B&J sessions.

But as stated earlier, I can see plenty of potential in your sail, especially as a school or club where you can leave it rigged.

Ha, ha. I love this forum.

To wit: Alap's,"best thing that happened to skiing was snowboarding" (true), and Zirt's reminiscing about his beloved Haut Routes' performance (also true).

Both so wonderfully off-topic. Hmm, anyone Jones-ing for snow as much as we are? Geez, I hope we get some. Utah's so dry right now, although our reservoirs are full (brrrrr). At least Zirt's still sailing, lucky guy. I'm thinking Mojave for Thanksgiving...

Of course you can't put fixed number on all sails. Deep camber sails will have smaller range but better lift, more flat sails will develop less lift but little bigger range, My point is that it is still VERY SMALL RANGE.

Northern California. Sacramento Delta. It blows in the morning & evening with a mid day lull in the mid teens. Sometimes it blows all day but during heat waves it may only blow in the early mornings. Did I mention that unlike the east coast the wind here always blows in the same direction.

Nice, what can I say. Well, for the rest of us, a windy day is a treat and it all different directions and wind speeds and..... https://www.youtube.com/watch?v=WaAyWwjLv8k

Yes, I know. We get people who fly all the way out here from Boston to take an ABK camp for that exact reason. It is far easier to learn a new maneuver when you have visual landmarks that never change and consistent wind.

The rig blowing away would be a concern.

The wind direction, comment EAST coast, I sail in Maine, the wind direction is not the same .
