I would make them slightly teardrop shaped with the pointy end toward teh rear to aid in lower speed efficiency. If they were round, as on a golf ball, the rear portion of the cutout would be acting as a wall during periods of slower speed cruising.
I like the idea, and have wondered myself why is was never tried on a high po boat.

Oh by the way starting a thread and describing here on line does not help protect it but rather actually hurts your ability to obtain a patent.

A ball moving through air experiences two major aerodynamic forces, lift and drag. Dimpled balls fly farther than non-dimpled balls due to the combination of two effects: First, the dimples delay separation of the boundary layer from the ball. Early separation, as seen on a smooth sphere, causes significant wake turbulence, the principal cause of drag. The separation delay caused by the dimples therefore reduces this wake turbulence, and hence the drag

It's been tried. Both the "innies" and the "outies", on smaller drag boats. You WILL get ariation, but "re-entry" gets too much drag. But if you wanna play with some hull designs, play a bit with the strakes. How many? how wide? flat, angled or cancave.? All will have different results, the problem is that it's harder to make the molds. I been playing with some "strake" stuff on the Cad, but nothing final. The best option is a variable strake design. Flat and wide on the front to stop from "stuffing", concave to get you some air in the mid and flat/concave to get you lift and speed on the back. A mold builder nightmare.

Anyone see the episode on mythbusters where the scaled up the dimples and but them on a car? They did several tests and confirmed it actually got better MPG. The original myth was that a dirty car got better mileage so the tested that theory then teched it up a bit by covered the car in clay then carved large symmetric dimples over the entire surface. Was a pretty good episode.

Spent 15K and I still have to stop at the gas stations, I'm getting 119 % gas milage and I have to stop and empty my tank every week.

Back in the days, I never washed my car, for that reason alone. Now.. I been watching "Top Gear" on BBC and all the Europian cars gets twice as much gas milage then the US counterparts. So.. I changed plugs +5% MPG, Fuel, air, oil filter, +9% MPG, Nitrigon in the tires, +8% MPG, Fuel octane booster, +12% MPG, New CPU chip and timing chip, +15% MPG, Light weight, alum rims, +8% MPG, Disconnected AC belt and AC, installed fan at dash, +12% MPG, Oil additive/less friction, +7% MPG, Taped all the cracks on the hood etc. +6% MPG, Airodynamic wipers, + 4% MPG, new trans vacum modilator, shifting at lower RPM's, +6% MPG, Lowered car by 3" with special spring shackles, +7% MPG, Removed spare tire, rear seat, etc, +4%MPG, Put in 93 octane gas, +3% MPG, Synthatic dif oil, + 2% MPG, replaced my muffler to a HPO muffler, +3% MPG, Removed catalitic converter, +7% MPG, Installed Formula 1 farings and air diflectors, + 4% MPG,
