I was hoping that someone really knew for sure... but until that happens, I do have some "hear say" evidence.
About 15 years ago we saw a could-be sister ship to this at Ilwaco, WA (a little port marina on the north side of the bay at the mouth of the Columbia R.).
It was made of welded aluminum. Some locals told me that there were 6 of them built and that the ostensible purpose was long distance cruising, single handed.
The one I saw has moved on and I have not seen it for, oh, about 8 years or so. It had twin propane tanks in custom holders at the back of the cockpit, and the expected bicycle aboard. Never met the owner.
FWIW, it looked fast... as does the one in the picture. Note that with no "main" sail all the sail handling is with RF headsails. I can only wonder if beating and reaching are what it does best... and that it would want to avoid heading dead downwind.
