A few years ago I kicked around the idea of a masthead float that would improve performance. Using a square top main and placing a foil on top to form a T. This would stop the air from spilling off the top and make the top more powerful. Much like the winglets found on modern aircraft.

Of course the problem is would it be class legal? Would you want that thing slicing down at you if the boat next to you capsizes?

I think for it to work a manufacturer will have to get involved a design a boat that uses it.
