Good point. I only know a bit about high speed offshore racing cats and the little one in the pics. Based on what I've seen here with this big cat I won't very be surprised to see one hit the 90's but that triple digit threshold is a real barrier to entry for most. But I would love to see it happen!

t top designs need to start advancing . currently boats run faster without them but that should be opposite . a t top could be designed to create minimal drag and lots of lift , just like an airplane wing . I agree that this cat may have all the lift it needs at high speed so they can design it to add stability and be very aero dynamic .

Now mono hulls different story , they can use lots of lift at high speeds . think of a wing (t top) providing 2,000 of lift. it would help pull the hull out of the water at higher speeds and would create much less drag then current designs . Also can you imagine how cool a big carbon fiber wing would look on top of a cc !

Whit know anyone that could design one for my sterling ?

Something like this


A big carbon fiber swept wing that can sweep back for docking

Lift always requires power my friend. Drag is a matter of shape, its area vs speed.
If you eliminate lift you go faster. If you REDUCE drag, you also go faster.

How about I just take that slow sled off your hands and you can buy a jet boat?

If you're out on the water, and you're in a hurry, you've lost the battle.
Everything will be there when you get back.

When does any boat catch enough air to flip?

The last time I saw a big cat try to run past 100 on the Pamlico it didn't end well. The boat turned right in front of our house and from the sound it was obvious the driver was pushing the boat downriver harder than any of the previous runs. Within less than a mile the boat went airborne. The driver was a airline pilot but wasn't able to control this craft in the air. Didn't realize until we drove down to Whichards but Reggie had been smart enough to get out of the boat just before the fatal run apparently realizing the boats limits.

A few days after the accident, a piece of balsa around two feet long washed up on the shore. One side was plain, the other painted "Fountain".
Must have been 35 years ago.

Not sure but I think that was the only cat of that size Reggie built.

Isn't it more accurate in boats that lift reduces overall friction by drying out the hull? That is the result of pressurizing the tunnel in a cat. To provide lift. Air friction versus water friction on the hull.
V hulls in smaller and heavier boats sacrifice forward thrust in order to lift the front of the boat. Tilting up instead of straight forward sacrifices forward thrust but helping the hull "dry out" which hopefully provides more overall speed. Fast by design, boats like Allison almost always can be seen with their motors straight back.

My thought would be to suspend a boat long enough to stay on the crests and smooth out the ride.

Best. Logic. Ever.

It is really quite scientific and logical and demonstrates our commitment to fulfill the wants and needs of the customer.

The Staudacher's from just outside of Bay City Michigan are my Hero's. I was fortunate to make their acquaintance when building boats for the Gougeon Brothers in the 70's.

Les built 53 Unlimited Hydroplanes and his son Jon, many National champions in the limited hydroplane class's and some unlimited hydro's too. In addition, Jon designed and built many competition unlimited aerobatic aircraft.

Looking to understand the dynamics of the Aero features for this new cat, I asked Jon as I was drawing the boat. "Jon, What actually is the air in the tunnel going to do for me?"

Jon's reply; " you know, I think about that a lot. I'm not really sure" :-)

Its not a bad photo, hull #2 does indeed have Fighting Lady hull sides.
Ok, ok....It is a bad bad photo, but hull #2 does have Fighting Lady hull sides.

300 Suzuki's
It is a fish/dive machine, less outfitting and it is likely to be lighter than Rays boat.
It will be interesting to compare speed/fuel numbers.

Otseg, you sir build one hell of a boat. I wasn't a cat fan until I ran across Rays build when y'all first started it. Hopefully one of these days I will be sending you a deposit for one a little smaller than the 39. Keep up the innovation as I think soon all the other cat manufactures will be chasing you "the new big dog on the block".

Maybe the old Dog.

We have been working on the business plan while completing hull # 2 to see what makes sense.

"There are hundreds of cows grazing below. The young bull says, "Let's run down there and do a cow!"
The old bull says, "No, let's walk down and do them all."

I don't know how anybody makes money building boats, now if you build a brand you can rake the cash in. Like charging $400 for a plastic ice chest, and letting people pay you to wear your logo on a hat.
