It looks more like an ice boat on steroids, or three windsurfers tied together, which brings up another question; are foils allowed in this speed attempt?

And would it be faster as a foiler? The only difference between a 50 knot "sailboat" and an 80 knot iceboat is the drag from the wet water vs. the frozen water. So, if they could lift the hulls up out of the water to reduce the drag, maybe they could get closer to iceboat speeds with a smaller boat? Like that one man foiling tri in the earlier pictures.

Even with foils they will never get the drag down to that of blades running on ice and the choppy water will never be as smooth as ice...but it sure is fun to watch the development.
