Brian,
Wanted to help display the look we are trying to achieve. Naturally it might work better on a bigger platform or smaller one does this help explain the vision for finished cabin house design.. A mix of old and new.. Would you call these ugly?

Speaking of the Indikon project and Journey catamarans, anyone happen to know their latest pricing and what is their speed range? I know Journey cats are meant to be fast and compete with the Mainecat p47 design which I think is prettiest of them all. I dont see any speed range for the indikon motor sailor or powercat, but judging by transom shape and size of engines (170-220hp) each side I venture that they are aiming for maybe low twenties?

Our MP52- Trawler was intended for what I thought was that perfect sweet spot of 10-12 and doing so on (75-120hp) each side while sipping fuel.
Prices for the Mainecat P47 and Journey 47 are both 889K I believe?
Wonder what the new 40ft indikon P4 will be, Did they advertise pricing at boat show?

All I can say you might be hard pressed to find a 52ft power/trawler cat for the 450K we are offering the Maltese MP52- Trawler for...
Don't even need to mention that the Mainecat and Maltese are only ones made in good old USA.

Do you have any other photos of the M-52 being built besides those two, kinda getting old looking at those same two pics.

N4712,
We have plenty of photos on our website which I don't think i can post here but they are easy to google at Maltese Catamarans. Be happy to share a build diary photo log that I've compiled over time with any interested party but will this do for now?

In design there can be subtle differences that add collectively to completely change the overall look. In the pic you posted the square cabin does look right.. but it has a cambered roof, overhangs, a shorter profile, the deck is also cambered, the cabin also has a slight taper. Many of these elements add relief and a shadow line that reduces the visual height if the cabin.

All the above are elements of proper design, both marine and dirt based design. Even the last generation of charter cats that have those vertical windows have all the above mentioned elements.

Also, the square cabin look may have been out of necessity.. composity have allowed us to design the swoopy designs that were not possible to do before wood was vacuum cold molded

Catman 54' Trawler Powercat

Have a look thru these multiple photos and specs,...more along the lines of a 'trawler cat'

54′ Power Catamaran Pilothouse 2005. Long range, 24′ beam.

Brian,
Thats a nice trawler cat but not really a fuel efficient option though with twin 370HP and weighing 46000 lbs. I do like the interior though and not bad price at 695K.

I know Journey cats are meant to be fast and compete with the Mainecat p47 design which I think is prettiest of them all.

Our MP52- Trawler was intended for what I thought was that perfect sweet spot of 10-12 and doing so on (75-120hp) each side while sipping fuel. And at 450K for "motor away" pricing its a nice addition to the cat trawler market.

Brian,
You claimed to have spoken with them (indikon and journey) about their projects. Surely a multihull authority and promoter like you enquired about the pricing? Was just Asking you to share the information for other forum members... Since you did not answer the question or address it at all I thought you missed it. You seemed to know about all the back stories of these designs and surely you have some opinion or info about pricing.

As for the Maltese MP52-trawler. It's just another offering to the field that I'm sharing with forum members. It's not the only one I am sharing info about. Clearly I like and promote all the offerings in the power catamaran market. But unfortunately I can only drive one boat at a time

Seems to hurt..

Maltese52 I like your posts and all your photos and information, good to compare the prices "Value For Money" is always the hot item.

Thanks Reiziger

Sitting in office today while bosses were out for test sail with Client on Lagoon 39 gave me chance to play with one of our Ads that displayed possible look of Maltese 52 underway. Have a look... Maybe Lagoon will build a version after all...It would be very easy to tweak out the Maltese Cabinhouse to replicate the look. All that for a whole lot cheaper...

Yikes!

10-12 and doing so on (75-120hp) each side while sipping fuel

120 HP with a very well engineered setup is 6 GHP per engine.

12K at 12 GPH (2 engines) is hardly sipping fuel.

1 NM per gallon can be done in most sport fish at 2X the speed.

FF,
Perhaps you should check your calcs a bit.. I said the boat was designed to cruise at 10-12 knots, which is just about hull speed for a narrow waterline cat. Surely you are not suggesting that it would take all the available HP to move her to that speed. We know that not to be the case, through plenty of available info out there. Couple that with the fact that slender hulls are more efficient to start with and you get in ballpark of much lower HP number needed to achieve that speed in a catamaran hull. The 120 HP at WOT theoretically burns 6 gal/hr and if you had two running at WOT you could be burning 12 gal/hr but at much higher speed, probably closer to 20 knots? The 75 HP option would have a lower top end speed but even better efficiency. Hull design was for efficiency at 10-12 knots sweet spot that most if cruise at and surely will be better than any comparable length trawler. Your average 52 ft sport fish running twin 800HP will be more efficiency exactly how again??

For reference, Journey catamarans LRC 47 shows fuel consumption chart that they tested against. They get 7.7 g/hr total at 10.2 knots using two 220HP engines with a shorter waterline length and heavier (albeit, very nice interior layout & finish) 37000 LB boat.

Agreed, that would be a big improvement.

PassageMaker's Boat Review - Journey Catamarans

...an excerpt...
Underway, the twin 220hp Cummins QSD diesels turning 20
x 20 x 4 props through Seatorque drive shafts produced a smooth and quiet ride at the lower helm. New 21 x 19 x 5 Michigan Wheel M500 series props are planned for hull number one, adding about 30 percent more surface area and an anticipated increase in economy and performance.
Beginning with hull number two, standard 260hp Yanmar 6BY diesels spinning 24-inch diameter props will be standard propulsion, adding 40 more horsepower and blade area, and reducing weight by 100 lb. per engine.

Fuel Consumption on that 62' Tennant design

The powercat I started this tread out with,...owned by a friend of mine,...and for sale now.

That's 1.1 nmpg

According to the article that is estimated to double at 12 knts of speed...
2.2 nmpg

I'll have to see if I can find an updated fuel burn from the current owner.

Sorry for that mistake.

>Couple that with the fact that slender hulls are more efficient to start with and you get in ballpark of much lower HP number needed to achieve that speed in a catamaran hull.<

While there is no question at SPEED slender hulls are cheaper to push (before plaining) . but weight for weight down at slow trawler speeds SL 1 or so a beach ball underwarer shape would have the least wetted surface , and wetted surface is the price at slow speeds , not wave making.

Back in the 1960 era when multihulls came on the modern scene the AYRS was the premier publisher of info.
The AYRS came up with a simple method of figuring "hull" speed for a variety of boats.
The old formula was created by looking at fat boats of the time , and doesn't work well for skinny fast boats.

S = L/3b X SQRT (L)

When run for some theoretical hulls it may be a bit fast , but seems to work.
