I'd describe the rig as a balstrom rig with a wingsail. There is an attempt to induce a foil shape at the bottom, but more would be needed higher up to be successful. A little more money would no doubt have been a big help to the inventor, who seems to have lots of good ideas. Bulbs are only good for vessels moving at about 3/4 hull speed, which is why they are only on ships.
What a clever design - you add the bow when it's in the water. I've never see that before. Plexiglass rudder? How cool. I love your boat. One question: Is the bow a separate part for transport or for ease of construction?
So how do you keep the sections together?
