"Outahia" is a 44C - mine is a series 2 with a different bow. I am fairing the insides just now, before putting the decks on. Started in Feb this year. I have pics but haven't even tried to work out how to post them here.

Is that different bow in relation to the one that joined the "roll 'em over racing team" at the start of the Gladstone a couple of years ago??

Well it is a different bow, which goes with it being a completely different boat. That wasn't a 44C. (BTW that boat is currently keeping it's owners very happy cruising the QLD coast)

AFAIK there are 3 of the 44C's in the water right now, with Outahia being the first of them. The builder of Outahia has another of the series 1 nearly complete, but right now he's building a power tri (Another Oram) for someone else. There is another S2 in Brisbane which should be finished in a few months, then mine, which should be around mid - next year, and two others down the sunshine coast that have just started. And one in Darwin which is being very nicely, but slowly, built.

The difference between the S1 and S2 is just that the bow has been made finer and easier to build - you just draw the two sheer panels together to form the bow.

Didnt think for a second that the owners wouldn't still be happy.

I'm sure even the best of us cock up occasionally.

Re-design requirement

A lot of thought on here about light construction benefits and cats, but perhaps thinking here is not radical enough:
STEALTH yachts designed as high performance boats, high speed boats. Stealth technology uses hydrofoil system, hydrofoil supported catamarans.

I kinda like the “M-hul” Stiletto:
The Stiletto, a Twin M hull vessel, is 80 ft in length with a 40 ft beam providing a rectangular deck area equivalent to a conventional displacement craft 160 ft in length. The vessel's draft fully loaded is 3 ft and is designed for a speed of 50-60 kts.

M Ship Co. | MS 80 Stiletto | Next Generation Hull Technology

How it works: M Ship Co. | Technology Index | Next Generation Hull Technology

Or:
Transatlantic21
transatlantic21: transatlantic21
Using solar power only the catamaran "sun21" is undertaking the first motorized crossing of the Atlantic with solar power to promote the great potential of this technology for ocean navigation.
The "sun21" is due to arrive on 8 May 2007, 6 pm, in New York, having covered about 7000 sea miles.

The boat: transatlantic21: Boat

I'm kinda drawn to the Shannon SRD's. Ongoing development of larger models are claiming ocean spanning capabilities with onboard fuel capacity.



Builder Shannon Yachts, Bristol , Rhode Island

Designer Walter Schulz & Assoc.

Length on Deck 38' 3"
Length Overall 40' 7"
Length on Waterline 37' 7"
Beam 13' 0"
Draft 2' 0"
Displacement 13,500 lbs
Water 80 Gallons
Fuel 280 Gallons



Besides they're very nice looking boats. Honey! Have you checked the lottery tickets yet?

I was alway's under the impression that those foils got added to boat's that underperformed in the hope that it would increase speed and help them plane better , which they usuall do.

Easier to do the design/build correct at the start.

Rick I like that style of Classic look boat.

Gord, that sort of device get's me sorta excited in a weird kinda way.

The ugliness is strangely attractive, and the party area up top, space for plenty of fun and frivolities.

Doubt there'd be any economy though, bit like this thing, but to me......pretty.

Those wave-piercing catamarans are designed and built a couple of hundred yards from where I work. I designed the liferafts and evacuation systems for them. They are impressive beasts that will go significantly faster than a nuclear powered aircraft carrier... but at the end of the day, they are still only "stink boats"

efficient powerboats vs efficient sailboats

I've got to throw my 2 cents in:

I prefer multihulls particually for this part of the world and the eastern islands of New Guinea. Shallow draft, stable and low power requirements.

Its a bit hard though to get sailing out of your blood, so my solution is for a motor sailer, the emphasis on the motors (two of them) and Basic sailing gear.
I have spent many miles coasting along with sails up and the motor at 1/3 throttle. Very little fuel is used but you do maintain a good average speed. Don't even try an build an efficient windward rig as i am travelling on a reach or down wind most of the time anyway.

I am going to use waterproofed four stroke outboards each with a snorkel. The saving in weight and cost is incredible.
Sure, I will need to store more fuel (petrol) but the fuel economy I can achieve by going multihull helps to make up for that.
From a reliability point of view I am happier with two Japanese built four stoke outboard than one heavy costly diesel. Plus the props kick up out of the way when needed.

Also, I am going for a motor sailing Trimaran

How much did that rig , sails and winches cost for your motor sailer again Beau??

Might buy a lot of fuel

efficient powerboats v efficient sailboats

Well I am off experimenting again.
I am testing Oceanic Lateen type sails, one on each side of the mast (for ease of tacking)
Only a short mast is needed, The two spars are aluminium and the sail is a very simple cut. very basic very cheap, but I will need some winches.
Plus all indications seem to indicate that Vortex's formed by the oceanic lateen sail lifts the bow of the boat
