200mph
 

Hello,

I have a question here, besides all the safety stuff what is really needed for a V bottom or Catarman hull to reach 200MPH? Does anyone have any links to boat descriptions that have done it? I know that it is probably not the safest thing to do, but to me that would be an incredible goal to reach. Any comments/ideas would be appreciated.

Thanks,
Lance

All you need is a bottomless checkbook:D

Sorry. Not very helpful, but had to say it.:)

lol I know that much :-)

How about an 80 MPH boat with a 120 MPH tail wind? ;) :D

Seriously, turbine power is the only thing that will get you to the promised land without rebuilding 4 piston/pushrod internal combustion engines after each 200MPH stint...

You could give these guys a call Callan Marine I believe they have been over 200mph.

Even with turbines you won't see a vee run anywhere near that. You'll run out of bottom long before hp. A tunnel hull is the only way to do it.

It takes two 1850hp turbines for Jetset to reach into the mid 190s.with a 40' skater. Also it takes 20,000 RPMs.

What would need to be done to that arneson??

Alot will depend on your prop rpm. There are different ways to get to those speeds. Its a function of pitch and rpm. Spinning a high rpm with lower pitch is easier on the driveline but tough on bearings. Running a longer prop will get you there but either requires stressing the driveline or alot of run in to make the power slowly. I'd recommend a shaft drive - Arneson derivitive with a rudder at these speeds.

Personally I do not see any problem at all with a Piston Powered Cat going over 200.

I agree with steve, it wil happen, but not just yet. heck if some one would build a realy BIG rotarty they could theoreticaly spin a cat to 200. or just cube a v engine enough, (look at the tourque v-12's) maybee get a couple of allisons turbo supercharged and it could happen sooner. but a v bottom??? no thanks not without wings and a propeller. heck I know of v bottom anphipious aircraft that only go 140 in the air!!!!

Ron P I thought the T58s were 1350hp and the T1000s were 1500hp . where did the300hp come from?

As far as V bottoms are concerned isn't Mike Fiore running high 150's , Two 1200 Sterlings in a 42 ?

GPS Doesn't lie

sy goldberg was tellign me teh othe rday abotu the 1000 island poker run. He was ina 42 something or other and they were running 102. The fiore's pulled up next to them (from out of nowhere) saw sy recoginzed him and figured they'd show off a little, slammed the throttles down and took of as if the boat sy was on was standing still.....

OR, just build the proper designed cat at the proper weight!

Puder..
Was this before or after Sy paid for the 4am breakfast entertaiment at Denneys??:D :D :D

I know Fusco averaged 177 in the New York Poker run. He did some mods to the engines and is running just shy of 200 on any given day.

The last time Sy was running 102 he had a bad fever...:p

The only time he will see 102 is his next Birthday:p

102, The number of Viagra Sy needs to get a hard on:p

102, The room number he and the catman shared in Miami:p

:D :D :D

What does "running just shy of 200 on any given day" really mean?

A cup that'll hold basketballs!!

tachyon, it means given enough room free of boat traffic and water calm enough to push the boat, it will run in the high 190s.

Been there, done that. Read about it in the first issue of www.extremeboatsmag.com sign up on line for three free issues.

If anyone would like to "Shatter" the 200mph mark and go over 250mph, contact Steve1, he has the ability to do this with a set of 1300's in one of his cats...no kidding!

1300's won't get you there (i.e. 200) - it takes more hp. 250 isn't worth talking about.

I am referring to this power in one of Steve1's boats and beleive me, he can do it!

Ron P,

I hope that "any given day" also includes a canopy and rescue divers....

ShipWrecked,

What kind of boat are we talking about? A drag boat, hydro or cat? I must be missing something;)

i am reffering to an Offshore Cat, designed and built by Steve1...he builds them under the name Cheetah...he has produced incredible performance with his ultra high tech methods. No kidding, No BS.

ShipWrecked,

Does Steve1 have a website? I'd like to get more information.

i beleive it's in the works, just PM him!

Thanks.

tachyon - whats the latest on the Callan boat?

mcollinstn,

Waiting to hear "official" word from APBA Offshore on weather they are going to allow turbine boats to race in APBA Offshore sanctioned races. They are contemplating creating a turbine class (might be called PXT). Unofficial indications are good.

Testing new drives (SCS) next week and preparing to run the kilo in Sarasota again around the end of the month.

Yay.
Hope the class thing works out.
Hope the drives are satisfactory.
Looking forward to the kilo results.

Thumbs-up and fingers-crossed.

Mike

Simply put - running in excess of 200 mph in an offfshore boat requires the right conditions (wind, water, etc.), the right setup, and a catamaran. It is the same reason Callan didn't run 200 in Sarasota before they broke or JT and myself only ran 195.6 in Cleveland (15mph crosswind). The power, whether piston or turbine, is here now.

i thought i remember reading in Hotboat mag that the skater called the "Sourcerer" was capable of around 200....using twin 2000hp's. they had a 3 or 4 page write up on it with some awsome pictures....the mag is on my boat (all wrapped up for the winter). anyone else remember reading this???

Nice show

So, let's get Steve1 to give us a lesson, that guy can go 300 mph if he wants,,,just needs the right crew behind him!

First off I wish everyone involved the safest event possible.The element of Danger is so great and the best thought out safety capsules are just that period untested and waiting unfortunately to be tested!

To be honest 10 or more years ago we spent a lot of time working on the parameters of a 200 MPH Boat and the finial design was nothing like I see nowadays! Nothing. These are like 150 MPH boats pushed to 200+ Bad news!

Our mentality was to design a much faster boat and run it well below the therotical IE: a 300 mph Boat run at 200 those were NOT our actual values but an Idea of the thinking.

In short a for real 200 MPH + Cat would look vastly different than the Pointed Box like Affairs that I see now.

We tried all formats even spent a lot of time with a reverse 3 Point design. Again trash canned! The Catamaran always won.

Power is there nowadays but the drives are not quite, but that is an easy fix!

hiperf2000,

Yeah, any poker runner knows that skater, truely awesome. Last time I talked to Rod in April 02 they were almost there. He said him and Ed will get it in due time, and to think it will be with pistons engines.
