I was bored the other day and started looking through googles patent search function and came across this.
https://www.google.com/patents/US201...IVhRmSCh2ZkwT8
Looks like it is only an application but the gist of it that I can tell is a hull designed with wakesurfing in mind with two pros rotating inward. Interesting design and I would be curious to know what came of it.
"In accordance with the invention, the boat hull is self-propelled, preferably by two inward-rotating propellers."
Another page for the same boat just extra stuff on the design with more refined drawings.

Looks like they are/were designing the boat with a center tunnel to direct the water and two V's on the outside to give you a clean port and starboard wave at the same time with the counter rotating props.
The designers/inventors are listed as Albert VIVIANI, Arye Laniado, Joshua Laniado, Yann Le Jeune, Pietro Lagioia and its Assigned to 3Madmen.
Anyone familiar with those names?
