Yeah, the guy who runs it has some of the check points in places that make it hard for more common sailboats to get to. One is under a bridge 12 feet wide and 8 feet tall, and you have to start from above the high water mark on the beach, so your craft has be light enough to get into the water. I think now that the T won it, they will add more obstacles. Sailing anarchy has some video's of the race. And one shows the T finishing or at one of the check points, and they are paddling it with the mast down.

They are using regular paddles, one guy on each hull, one forward, one aft.
