How silly!There is a short sailing video on YouTube but the poster (Jeremie's brother, I think) has asked that it not be shared.
That looks fun!I think it was built by Jeremie Fischer (known for 'Equilibre') in Martinique with the intention of competing in the Route du Rhum. There is an image gallery here: https://imgur.com/a/bQse540 . There is apparently another imgur gallery showing construction but it doesn't seem to be loading for me at the moment.

Latest status seems to be:
Probably. There is not much hull in the water. There looks to be a daggerboard/rudder aft on the starboard bow, but no apparent sign of one forward on the port bow? Hence the mods from red sails to a blue sail?Cool boat. From the angle of hull tracks in the water, it appears to need more leeway resistance (daggerboard?).
That is a still from the video clip. During that film the boat seems to be constantly, gently, rounding up with the aft sail sheeted in - just before the end the foresail shakes and the aft sheet is let go. In the picture with the blue sail there are boards at both ends but they seem very small and must be aimed more at trimming CLR than providing substantial leeway resistance?Probably.

But could also have been photo’d whilst changing course?
I was referring to the one minute video where it looks like their heading was steady but they were slipping to leeward. Why would they be turning to windward to set up for a shunt? Too bad the video stops just as they were about to shunt. Very cool looking boat.But could also have been photo’d whilst changing course?
Shunting that huge crabclaw in heavy air might be a challenge. The simplicity and efficiency of crab claws has always interested me - maybe a Gibbons rig would be easier to manage - however I have a feeling the crabclaw is better to windward.I sailed on a crab claw rigged proa in New Zealand and was very surprised to learn that they can flog. When they flog the lower spar flails around and it's kind of alarming. Not that I don't like them as a result. The boat was a ripper. The "Toroa" Had the most amazing motion in a short chop and around 20 knots of wind.
Man, more degrees of freedom is the opposite of what you need.I think that an easy fix for the Gibbons would be to hang the sail from a parrel attached aboud 25% from either end of the spar so the sail could be pulled forward on the mast when shunting instead of the mast canting .

Rounding up into irons before you get enough speed is a slow speed balance problem. Having a large draggy ama to windward can only make it worse.The problem with the Gibbons rig and non canting rigs in general is that the CE is too far aft and tends to push the aft end over before the boat can gain enough headway for the foils to generate sufficient lift to keep the boat out of irons, I've been trying to compensate with a large sliding leeboard on the ama, low rocker, and balanced rigs with very limited success thus far.
harryproa may actually have an advantage in theory here, having the weight to windward creates drag that tends to rotate the boat into the wind so it might be slower to go into irons coming out of a shunt giving the foils more time to generate lift, seems like a small upside all considered though, drag being, well, a drag.
Upwind, it doesn’t.I've always wondered, how do you keep the windward staysail from spoiling the airflow to the main? did you get the idea from John Pizzey's atlantics?
The issues with the rig didn't really depend on the changes Gary made, IMO. I never sailed without a boom, but I fixed the mast vertically a few times with my original white sail. It didn't make much difference. The issues I had centered around a big sail swinging around one point of contact at the top of the mast. Making that point of contact slide around seems like it would not make the situation better.Are you thinking Gibbons rig? basically a latteen rig with the non-canting mast in the middle? Or the Dierkings rig you had before the schooner?
