I just made that name up...but whatever you call it, it's a concept worth pursuing.
The first hull shaper I knew who tried this was Tony Staples, back in the mid-70's. He shaped a conventional hull, with a little extra thickness in the back 1/3 of the deck. Then he scooped out the deck along the rear rails, creating super thin, flexy rails with a sharp dome deck.
The above board is a Mandala 1 + 2 hull. I have no idea the dimensions, I just saw it the other day and wanted to share it.
