V. Hulls vs Cats.
 

Yadda Yadda Yadda. you aint lived till you run across the water in a Hydrostream. Hopefully this year I will add with a offshore 2.5efi. on the back :eek: :eek: :rolleyes: :rolleyes: :p :p

You mean skimmed.... :D :D :D

Hydrostream has great Tunnel hulls, cats are the best!!!! :D :D
Caleb

Timewarp don't forget about the HST hull. :D :D

I like the HST's actually I am keeping my eye out for one, just to play with,they weren't the race boat that they were designed to be but they are a fun boat that will run through some pretty rough water for their size.
I learned how to powerboat in Hydrostreams.
Caleb

Whats wrong with a hydrostream? :p :cool:

Not A thing!

OK, call me stupid, call me ignorant. Rivergirl, you just call me ;)

What is the difference between a tunnel hull and a cat? :confused: :confused:

IF IT AIN'T A CAT>>>>> IT'S GOT TO BE A DOG!!!

I don't think there is really a difference between a cat and a tunnel hull they call the small ones tunnel hulls and the larger ones cats. Some cats have centerpods and then they are not refered to as true cats by the purists. The depth of the tunnel probably has to do with whether they are called cats or tunnels but they still call it a tunnel if it is on a cat so I'm sorry but I don't know if there really is an answer to that question. :rolleyes:

Hydrostreams: The drivers love them and the passangers just cry :eek: :eek:

That cat/dog line is a good one...is that original?

Originally someone said it, it's been around for years. :) :D :)

It might have been original when it was put on the boat I took it from :D :D

A cat can claw, but the dog can bite!!! :eek: :eek: :eek:

Just remember this.

A DOG can kick the **** out of a CAT.

:eek: :mad: :eek: :mad: :eek: :mad:

Dam cat drivers...

:D

Boys...give me a little credit. You didn't think I was serious?! It's been on every thread involving Vee's and Cat's. :rolleyes:

THERE IS A DIFFERENCE. A tunnel hull runs more on the wing effect, usually wider tunnels and around 80% aerodynamics and 20% hydro. The Cat is typically a narrower design and depends more on compressed air with 80% hydrodynamics and 20% aero.

Screamin:
By your definition, there is a MAJOR difference.

It is very rare that the dag ever can catch the cat

:D :D :D

So if there is a difference between "cats" and "Tunnels" name a few!

Good question SuperCharger....and welcome to the board. Guys, please name a few...

Thats because dogs cant climb trees...

:eek: :mad: :D

Hey NHRA910,

I've heard that one before !! I'm sure you can figure out who it was.
Sorry about cutting you off earlier, but work has been chaotic (sp) this morning . I wish I would have stayed in bed !

To answer your question, Yes I love the truck. It is amazing , it may have the same body style as the old one but it is completely a different truck. I can't wait to tow something with it !

I hate Hydrostreams. I blew up two engines racing against them; racing against the same boat too! Got to get him out in the gulf someday...

Kent don't even try to keep up with him. You will make is a cool three if you are not carefull :D :D If the guy can really drive it good they can even run at speed in the rough stuff as well!! No fun for the passangers :eek: :eek:

Cats & Tunnels
 

There is no difference between a modern-day catamaran and a tunnel hull. Both have twin assymmetrical hulls, and use aerodynamics to assist hydrodynamic lift. No difference...two words, same meaning.

crazy
 

Hydrostream = suicide mission. Those things take big balls.. defintley boating on the edge. This guy screams around the flats near my house in one 1ft of water. I swear he's doing over a hundred ....teedle ..teedle . Then again people think I'm crazy doing that out in the gulf.

How fast are they?
How much water do they draw at speed?
What kind of props?

Maximus

How fast are they...... Well that depends. My Viper was 15ft long and had a 150xs on it and it ran almost 80. I then modified the engine and so far we have been spinning a 28 pitch up to almost 6 grand even a little more. I think we need to try a 30 pitch. My other buddies Volero runs to the P on MPH on his 80mph speedo. Put a 2.5efi on it and you would be at about 105 is what we have been told. They are very fast boats.

As far as what kind of water do they draw at speed, well figure that the prop runs half in and half out of the water, so you are only drawing what is below that because your observation of the boat being above the water is a good one :D:D The only thing in the water is the bottom half of the bullet and the skeg.

How much water?
 

Maximus: Your question... "How much water do they draw at speed?" At high speeds, your boat will be completely "planing", and so all the wetted surfaces of the boat are actually planing "on top" of the water. (This is differenct to very low speeds, where there is also a "bouyancy" contribution too). If we know the configuration of the hull surfaces, we can calculate the sf of wetted surface or length of wetted surface of your hull. The total drag of the hull is the combined hydrodynamic drag of the wetted surfaces + hydrodynamic drag of lower unit (if I know the lwr unit design, I can tell you that drag too) + some aerodynamic drag from exposed hull, motor, etc. surfaces.

Often the motor (lower unit) drag can be the most significant drag contributor at very high speeds. Motor drag is influenced by the design of the bullet and skeg, and by the "X-factor" (amount of lower unit in the water) at speed.

thx
 

Thanks for the info guys. I'll stick to my big cat. I get the "willys" watching that little thing fly(keep thinking a manatee is going to pop up in front of it) . Yikes.

Cat and Dogs!1
 

Nickslick,
Just wanted you to know that my Cat came from the Jungle, His name is Leo and he weighs 625 lbs. Bring on your Dogs!!:D :D :D
