Terminology

When building a boat that is as unconventional as this one it seems that there are all sorts of boat parts that don't have appropriate names. For example, the rudder/surfboard combination at the bow is a real struggle to name. It's not technically a canard, even though the boat is in a canard configuration. "Ama" doesn't really work either. "Float" sounds like a pontoon boat and doesn't do it justice. Maybe "rudder board"? Anybody got any ideas?
