Y2K with airated bottom
 

Jeff ( JC Performance) was at the shop last week to drop off a prop for the turbine. He was also admiring the new bottom. He thinks this bottom will be the ticket fot this hull. He also told me about a hull that got like 6 mph from airating the steps on their hull. I've heard of this for a few years now. And it got me thinking. I even ran the idea by Coen. He didn't kill it either. Who knows.... maybe down the line I can experiment with it. The hull would probably look something like this one.
Notice the black holes in the steps ?? Hmmmmm. Might have something there.

Nice work Rick!!
Ive heard on some bigger boats that they run the exauhst through the vents. Would that work on a Y2k?
Anyhow the new bottom Looks Awesome!! Im sure it will run even better!!!!!!!

I saw a 39' Outerlimits with air holes in the steps like that at the Hartford boat show last winter.
It was rigged with twin Merc 600sci, Bravo XR, 6 blade H props, and was supposed to run close to 100mph.
Sounds like a great idea...:cool:

Naughty Boy !!!!!! :evilb: :evilb: :evilb:

Yep, Outerlimits has been doing it for a couple of years.
When's the first boat with the new bottom going to be done??

Isn't OuterLimits the boats that spinout in every corner? I'll keep my bottom thank you. Sometimes safety has to be a larger concern than a couple mph. Maybe make them as a race only for non family boating situations.

Where do you get your info. There have been some due to driver error. Look at Ol's new race boat, it turns on a dime. The 42's were the ones that had some of the handling issues at high speeds. I was on one at 110 and it was very stable. We also did a nice wide turn at 90 and it felt totally hooked up. The step boats only spin out due to people's inablility to drive a boat, and push the boat to it's limits. Outerlimits is one, if not the leader in Vee hull's and now Cat's.:D

fx10, you may want to contact jack domick, from Hydra Powerboats. I think he has some experience w/ airation.

I have some pics of a Kryptonite hull w/ air outlets at the step. Not sure if they plumbed the exhaust out it or what.

I personally think it would be worth trying.

ceptor, can you post the pics ?? Thanks

Wish I could, but being the cheapskate I am I haven't ponyed up for a membership.

Email me at wagnerboats at Y! and I'll send them to you (didn't type the email addy...seems like when I have in the past I've gotten a ton of spam afterwards).

Did skater go out of business?:D

How do the aeration holes work? Where is the hole routed? I've never heard of this before, so please excuse my ignorance! :-)

all the 30' Phantoms have them, John once told me he would only believed they worked if he could plug up the inlet hole while it was running as see if their was a difference.

One of the top.:D It's wicked!!

Thats Better :D :drink:

Eddy,
Wouldn't a plain ol ball valve work for that. I would luv for at LEAST the forward step to get airated.

If you use the exhaust to do the airating then switchable exhaust hardware could be used. Just replumb such that instead of routing through the prop you pump it out the bottom. If that is too restrictive, then only have part of the exhaust go through by limiting the rotation of the butterfly valves.

The 29' Extremes have them as well!

here is my 1981 Challenger 21......... with an Aerated bottom... this is a RARE boat.
