Fully Aerated Hull?
 

Thought it was interesting.

I wonder how well that turns

Very cool idea

That seems pretty slow. What's a 300XS supposed to spin to?

Full-aeration requires a more active system (pumping air bubbles) vs. passive system (step bottom hull). Mitsubishi has come out with an 'air lubrication system' for the shipping industry which creates a carpet of bubbles under the entire hull of the ship. This is where boat racing should be headed.

HUH??? "So we did a run at 70.1 mph and then released the throttle, and the boat stopped as though you had put your foot on the brake " Not Good !.

Think - "Air Hockey Table"

Hallett had a hull design a few years that had holes on the side of the boat that directed air directly into the front part of
each step , they have since changed the design completely, and now use a semi-tunnel at the back ...very interesting .

Pretty sure this has popped up before, but yea stopping like it has brakes tells you something is way wrong. I can't imagine that those little holes could move enough air to out weight the drag of all that crap you would drag through the water. remember to get the hull to pull air down you must create a vacuum (drag). The question any aerated hull must answer is does does the ends justify the means. 2646 lbs and 300hp should do better than 70

ever try and float in a bubbling hot tub. you sink..your better off trying to remove the wetted surface not add to it.

didn't Ohio Steel have something with jet style intakes on top of the decking and it vented to the steps of the haul?

I thought several of the boat manufacturers in the late-80s to 90s attempted this. In the early days of designing a "ventilated hull", I remember several pictures and articles about vents in the deck to break the vacuum and introduce air into the water. I even remember some articles about attaching electric blowers to those vents to force air down to bubble the water to reduce friction. In the end, my understanding that the reason the vents on all AVS hulls go all the way out to the sides of the hull was to break the vacuum and allow air to be sucked in above the waterline, down that "groove" and under the hull. It seemed like it was a manufacturing decision however, as all other options created stress points and more parts to fail (with catastrophic results).

We tried it with a few 21 foot Shadows in 1980-81 ...didn't do much of anything, but they were pad boats and the steps we put on them didn't make any improvement either...except for handling...which went in the wrong direction. I agree with the earlier poster who nailed it by saying the best approach is to get as much hull out of the water as you can.... and then maybe aerate the remaining wetted surface.

T2x--just noticed the photo on the avatar. I worked at a marine dealership here in Texas when I was 18-19yo, and "pit crewed" for the shop, that raced a cab-over with an inline-6 Merc with 3 exhaust stacks out of the cowling!!! Loud, awesome looking, just fun to see and hear. Looked kinda like your pic, except with huge shiny exhausts! Blast from the past!

Perhaps something like this?

Man, that just makes me smile!!!!
Thank you very much! Outboards just don't have it anymore!
