should run the air intakes back into low bilge area. will suck out any water and fumes when under way just have a high spot in line well above waterline
This is what large freighters do to save fuel and increase speed. And no the props don’t suck air, causing cavitation. The reason is the propellers are below the air in clear water. I don’t know the boat builder here but I’ve been in the boat building industry for 38 years and this hydrodynamics 102 in play. Modern hydroplanes use this kind of technology. So l would have to say to you boys that built this hull good job! I hope you sell a boat load of these and laugh all the way to the bank.
In order to say if a bottom is efficient or not, we need to know Keith and Crouch numbers. Can you supply that? Aletrnatively you can tell me all the data of the tested boats so that I can calculate the coefficient. Thank you!

This video is detailed but he did not mention the real fuel reduction comparted to an equal boat ! Is there a real reduction with the air lubrification of the hull or just a softer feeling in boat handling ?
Applying for transfer to U Michigan (Naval architecture & marine systems engineering degree - bachelors). Fell in love with lofting in a wooden boat bldg class I took in Sausalito, Ca. Since then have spent a few seasons working on sportfishing boats. Now I want to design saltwater hulls in the 22' & up out of modern materials & techniques designed for nearshore & offshore fishing. Any advice for someone starting a formal education? Where might you suggest I intern in my summer months when I transfer to UMich? Thank you.
Hi Rob, The Antares 27 is the only Antares from the range to have the Airstep® hull that cuts gently through the waves offering a comfortable ride and safe navigation.
how does this effect cavitation of the prop or water pump? obviously im just being overcritical? im not disputing the advantages im only a dumb country boy that loves his ghetto sunbird with a 30 yo evinrude askin a question
should have blocked those air ducts and repeat the tests.. :)
Don't think this was a good comparison as there was nothing to compare to like for example the exact same boat with a typical Hull.
Sales video disquised as a test,they didn't even block the air scoops off to do an an A/B performance comparison

It works great on my boat. Don’t know what you are talking about
Looks good but with no definitive fuel use etc comparisons ? Infomercial
Known working laws of physics.

I remember people kicking this idea around back in the late 90s early 2000s.
Why they just dont put the exhaust of the engine on the air step design rather than drawing it out from outside on the bigger model
I'm guessing that it would polluted the water
@@fitrianhidayat I hope that's a joke
I thought up this bill design 20 years ago for airboats!!!!!
I've been kicking around ideas like this lately for improving performance on my electric motor
It probably won't work because your propeller needs to move the water so separating it from the water would be a bad idea.

Does the air forced drawn by itself or by some kind of compressor ? And on high speed turn does the stern slides excessively since it is air lubed?
Drawn in by itself
Dose the Air step add to cavitation at the propeller?
I don't think so because the bubbled stick to the hull.
i asked same same.... cant disagree with My Perspective either good answer
Thanks, what a beauty

Did you test one motor verce two
One would think that cavitation would occur with air introduced.

Finish your degree?
I was thinking you going to use pressured air. I just don't think the air has enough pressure or volume to go there and do anything useful.
Is this design used for the Swift Trawler?
With all that air how does a transducer work ?
I wager that Hull is VERY NOISY!
Nope. Not at all
Can you get a 300 instead of twin 150’s?
Does the Antares series utilize the AriStep feature?

Notice no data on fuel consumption. That says alot.

Chop ? 😆
Not anywhere near convincing!
BS
This is the worst marine marketing gimmick. A terrible joke in boat design
Worlds great on my boat.
