28'-ish Single Engine Vee w/ true Surface Drive
 

Has anyone else ever built/rigged/seen one?

This one is just being completed; and will begin dial-in shortly:

what's the power :)
im shure something big
:cool-smiley-027:

OMG!!!! That is feaking sweet.

That is bad a$$

I'll be surprised if it works well. A friend of mine spent a lot of time and $$$ installing a single Arneson 6 on a 32 Sunsation. The boat was very un stable and almost out of control at 70 mph. He was so disappointed he spent more time and $$$ and switched to a konrad drive.

The boat looks great. I hope you have better luck than he did

Would you be suppressed or surprised?

Buck

I would think comparing the two boats is apples/oranges. Isnt the sunsations bottom vented and notched? Besides, the skeg on this drive is huge and messing with props can fix most anything.

I think that Sunsation ran 101mph but had a very hard getting on plane.

I think it looks like crap. But thats just MHO .

I am looking FWD to the results.

NO TABS EITHER????

Even if he did hit a 100, getting on plane was just one of the issues.

Sydwayz ….. I really hope the AT runs well for you, please keep us posted with the results.

I think I would want a much longer trailer, say with a big rear bumper :)

The results will be interesting. What HP number?

I Would Think That If Someone Spent That Much Time And$$$$$ They Would Have Researched It In Great Depth. I Have Seen One Single With A Arneson Drive And The Owner Claimed It As Uncontrolable He Could Not Understand Why Someone Would Do That. But That Was Then, This Now. Sure Hope You Have Good Results.. (COULDN'T DREAM OF BRINGING MINE UP ON PLANE WITH ONE ENGINE/DRIVE)

got a bow thruster??
Looking forward to the trial runs.

This boat is/was an experiment; built for an guy who came to us wanting this specific setup. This is not a conversion. Dialing in is going to be a joint exercise. When the trailer was built, the boat had nothing on the transom; so the trailer is just temporary as is. The boat has not been in the water yet, so tab needs are undefined at this point.

It's something new and different for AT.
Who knows what's next?

I am going to really interested in the results. When I repowered a 28 Cigarette I looked into this pretty seriously. I could not find anyone that had done it before or had experience with it, aside from the 18 foot Donzi that is now infamous for his project. The single biggest part of this project that eventually turned me away from doing it was the idea of docking. The limited thrust angle vs. a conventional outdrive sealed it. Plus you really need a hull that is a good candidate for this, meaning it has enough bow lifting characteristics on it's own to bring out the benefits of this drive/set-up.

Really hoping for the best here for you guys and can't wait to hear the results.

I've always been interested to see what one of these big 28's would do with a twin arneson small block set up. If it doesn't work with the single you should try and talk the buyer into going with twin 350's. Good luck, can't wait to see what happens.

I think you need to call Dave Bottage and get your story straight.

Dave had issues getting on plane.

Dave did not have any handling problems. The boat docked better, handled better than the Bravo he took off, but did not get on plane better in his application. A far cry from what you have claimed.

Now, lets not discuss why Dave was banned from OSO and what he has now.

Didn't JC and Masher get their Activators with single Sixes to run pretty well?

Hey Rik, You missed this one

Didn't miss it. I do not know the application and was not involved with it.

I was referring to Dave Bottage and his application that you also mis quoted.

If anyone needs Dave's phone # I can send it to you.

I agree

Isn't there and old Sanger Tunnel that runs a turbine and single Arneson running around in the Bay Area?

There is a guy on Donzi.net who's doing it to a 21 either it's a GT or a Hornet, I can't remember which. He's been at it now and then for over six years. He just recently bought himself a Donzi 22 Classic, so I wouldn't look to see progress move faster now days. :)

The question is... why?
Is he running big power?
And no point on doing sbc's w/ arnesons... bravos will be fine.

10% more speed with the same power is the general rule of thumb.

Stormrider - I was thinking the same as CUDA. 10% more speed with the same power and still have reliable power. Efficiency is also a big thing.....er..should I say less gas.

Python82 has a surface drive on his 24 python. He liked it quite a bit.

We built like 4-5 of those. 29' Sanger Alley Cat with a single PT6 850 hp Turbine.

Back in the 80's we got 129 mph of those. Fun boats.

I guess we'll see, cuz speed is nothing w/o control.

I don't understand why there is always a confrontation when someone brings up surface drives....specifically Arnesons. There is a right drive for every boat and multiple drives work well on many boats. If you've never driven a boat with Arnesons, I highly recommend it. I've driven boats with TRS, Bravos, Imcos, #3's, #5's, and Arnesons. They all work well on different boats. I own a 30 Sutphen right now with twin small blocks and Arnesons. It handles AWESOME!!!!!!! It gets on plane with a quickness, It hauls a$$, it throws a kick a$$ rooster tail, and it docks like a champ. My hull is one of those examples that would also work well with Bravos, which are great drives, but I wouldn't give up the Arneson for anything......

Sorry for bit(chin but DAMN!

I really hope the AT with the single runs well.:boat:

So how did it run? The boat looks finished.What power is in it?

It should be interesting to compare the speed diff if stock power to a bravo set up. good luck and keep us posted:D

walter, i'm not convinced a single asd is the way to go.
I think if they were so great, you'd see more.
Now its a different story for a twin app.

And i'm concerned w/ handling at the dock.

I'm with CJ, it looks goofy. But if it'll run a 100mph who cares!

I'd be interested in driving one myself. I love my twin but am not sure how it would react with a single. I hope we hear more about this Active Thunder.

I actually think it will react fine around the dock. The only thing I do with mine around the docks is trim it down. This helps it react a little quicker in getting the thrust under the stern.

Again, no tabs installed because no one is sure what the boat will need, yet. It has not been run yet. It's getting 650HP.

My 24 with the Arneson is just as easy to dock is my 28 with twin Bravos. I would trade my Bravos for 2 Arnesons any day.

The only thing on my 24 that I have not worked on is the Arneson.

and Rik is the real deal

Thanks for the offer but I already have it. We talk quite frequently. I'll ask him again later



What ever the story may be from other peoples past efforts. I do feel this is a great R & D project and I hope that it works well for you guys. Please keep us posted on the results.

A number of years ago we converted a 24 Excalibur from a jet drive to a single Arneson power with a mild 502. Never had any major issues with plane or turning -- best was 75 mph. Dicked around with a few props to gain a little, finally a 4 blade clever from Hoss cured a lot of problems.

I always thought it was a neat project but after it was done we should have just went with a good sterndrive.

The problem is in these applications the stern drives simply suck.
then you would be like the majority, unfortunately broke down.

Big power x Sterndrive = one upset person:hitfan:

jeff,

mild 502 does not = big power.

I can see why the AT went w/ ASD; 650hp.

but jeff, these are not big heavy boats like 38ft plus.
many a smaller/lighter boats w/ big HP running bravo style drives w/o many probs. you have to know how to drive'em.
Now, the bigger heavy boats are another story.

i had 550hp in my 24 w/ beefed bravo... not a problem, and still none 3 seasons later w/ different owners.

you are the exception, you know how to run a boat. Most guys I see around here are sticks to the wall, dont let off, run 5000 rpms all the time, and then cant figure ut why their stuff does not last. I missed the part about the mild 502's. So their is no misunderstanding I agree that that surface drives are not best for all applications. I do prefer them for their simplicity, track record, cost, but there will always be a give and take in what ever we choose. Jeff
