I saw that the other day too. Looks pretty interesting, I think it was made at marco boats as there is one on their facebook page that looks identical.

oh man just when i thought BDC had me drooling. i like how the site explains the basics to newbies to cats and their benefits. although it doesnt seem to point out there flaws, for obvious reasons haha.

i love cats, they are more common in aussie imo where i had a glass one.

it has the internal beam of a similar sized frewza external beam, now thats spacious.

the maverick wont be any closer to my meager budget than the BDC anyway. but nice to dream (find ways to make it work).

Flaws with cats has always been cavitation with single engines - age old issue, the aussies got there a bit more with the Webster Twinfisher that had a splitter pod at the back, a great design in it's own right, I don't have enough experience with single engine cats, but could be an issue still grabbing 'air' with one motor? The old Markham Whalers were a great design but also suffered serious cavitaion issues, the one I went in did anyway. If you want maximum beam and freeboard, go buy a FC dinghy!

Cavitation makes sense , they make some big claims on the ride being superior ( wouldn't be hard if comparing to some popular pontoons) is that only on a nice sea , how do they go on the chop?

Cats handle sloppy conditions really well, I find ours drier than monos, 

swells are similar to monos without the 'twitch' you can sometimes get if you have a cross chop.

I dont know if I'd like a catarmaran with a single motor, 2 motors give a truer line and keep it true.

I get you having a twin motor cat.
Superior to be sure.
But the price point for 1st timer Cat owner/buyers is OTT,do you think?
Perhaps the single motor Cats can give boaters a taste of the many benefits of a Cat over a Mono?

Thoughts?
 
Peace.Via superior firepower..

In the world of boating money doesn't come into the equation guys see it want it buy it think about it , in that order .
Maybe the cat hull was designed by cad and is perfectly hydronamic in theory ( is that a word ?) but they didn't factor in cavitation in there design parameters.??
All I know it's a bloody nice website and I found myself thinkin man I would like one of them after browsing it .

Back in the 70's Peter Spurdle (Whitianga) built a plywood 32 foot cat with the same hull design as this one. It was a displacement vessel, and very seaworthy. He took it up to the Pacific as far as Guam and she was a great cruiser. In the 90's Jim Young designed and I believe it was built a 20 foot cat with the hulls reversed compared to the Maverick here - straight outside sides and the curve going up the inner hull. Plan was to move more water in towards the single engine. Not sure what happened to that design.

boat has 2  30hp mercs on it. todays prices they are around $4000 each.
A new 60hp would set you back $10000, aprox.

what I like about cats is the fact you dont have as much hull in the water, easier to push.

Lot of difference between a catamaran and a tunnel hull...

Not 100% sure about their claim of requiring less HP than a similar sized mono.

My previous boat was 4.5M mono, with quite a shallow V. 50HP was too much HP for it. It would plane at low speed, and sip the gas while doing so.

Surely having less surface area in contact with the water results in the requirement of needing more HP to hold on the plane, and at higher speeds

yea, I dont know about that..

when I look at the big cats, Ultimate Lady for example,, theres a lot less boat in the water than a comparative length mono..

its just an opinion, I have no real facts to back it up..

I know we can go a lot further in a 5 mtr cat with 2 30's than a 5 mtr mono with a single 60..

Indeed - less boat in the water means less drag and higher top speed. I however note that ultimate lady is pushing out 2400HP.
For a monohull to produce the same speed it would take more HP simply due to the increased drag.
Economy and usability are not all about top speed however.
