Would be nice to try but can't see I'd dig it. Not much pull from the sail, no board movement - just a bit vanilla

^^^ agreed - fits between SUP and 'normal' windsurf for me. But between SUP (no wind) and windsurf (16kn) is beer weather
I'd be worried about cray pot lines here

why such a small sail?

I think we will have to see where they end up. This is just the beginning, although the AHD has been around since 2010, and Rush Randle was using one over 10 years ago. They are going to become a lot easier to sail and control at speed. They are very efficient already and will become more efficient.

At the moment the only one that was built as a windfoil board is the AHD.

We have to see if you can use the same fin box for a foil as a fin. Boards may have to have an extra box to be well balanced with a windfoil.

I like the concept and would be a new type of sailing to explore. However, there would be very few places/conditions that this could be used in South Australia due to the weed. October is fairly weed free in metro waters (after December, forgot it), and Boggy lake is always weed free, but has lots of big carp .

In kitesurfing there is quite a lot of interest in foils, as they are the best racing machines in the sub million dollar bracket. They also have a lot of light wind potential due to the efficiency of the foil.

With windsurfing, there may be this small sail appeal in that if you can get the foil going, you only need a small sail to keep it going. And there is the interest in having enough skill to gybe one on the foil. I still haven't seen a video of anyone doing that.

This shows the start of the sort of experimenting that needs to be completed before we get a high performance windfoil, but this was recorded about a year ago and maybe it didn't progress?

Interesting that he's put in another fin box about 10" further forward

That looks like fun to try once at least. I showed the missus and she said that we should go to New Caledonia for a holiday.
Any windsurfing resorts/hire businesses over there?, I'll book it in before she changes her mind. First day of winter tomorrow and the water here in Tassie is starting to get a bit chilly.

Its a pretty easy windsurf destination as you can stay at one of the hotels near anse vata beach and just walk over the road to hire gear off the beach without even needing a hire car ( unlike Maui). It had another big advantage over Hawaii in that there are a lot less Americans though it is a little funny to see the locals dressed up in woolly sweaters and big beanies in the barmy July conditions (this may be a Tasmanian "thing" as it is the middle of winter for them). Its been a long time since I have been there but they used to do a good job of keeping the windsurfers and kiters separated, hopefully that still continues.

So... If you could sail dead upwind you could go sailing in 0 knots. If you got a little push to start.
