boats that are designed with car aerodynamic method?

not much is new really !!

If i was designing a new smaller boat about the 18 to 20 foot i would be going all out to make it as efficent as possible both aero and hydro and light weight using better materials totally through out ,No side decks and no fore deck so more much more room inside ,a bracketed motor even more room and better performance ,all rounded Gunnel and hull to deck join , No wood used any where in any part of its construction so weight will stay the same .Infusion is a option for everything but not that an important consideration !! And it would be a tunnel design ,stable, fast and excilent riding in those bumpy harbour chops . even on the ocean waves and rollers they are really stable ,would use a single outboard not twins !!. I have seen the begining of just such a project that was shelved a few years back becasue the time was not right !!
The company had used some of the ideas and they worked really well ,We made just 2 boats and testing was outstanding and sure raised the eye brows of some old die hard mono hull boaters ,then the boating industry fell over yet again . :idea:

 

start with an A class, its abox rule so you can make it very aerodynamic and with very low water drag to will have a big effect

 

Ille say it again there is no boat out there I would buy . I have posted what I want and been told its not feasable. Lines after lines of white boats with fly bridges, can you spot the one you want.

Have we not got a power boat without a fly bridge,---I don't think there is.

Light light light weight so light designers don't want/ cant do it it.

I am paying,--- not the designer. Times have gone and I cant afford one any more.

Alec in Thailand was the only one that said he could build it at 250,000.

This was 3 years ago at least.

Designers are the ruin of boat building industry.


' Ooooh no you cant do that --im much cleverer that you and I say it cant be done.'

 

You also had an option of designing it yourself, did you?

 

Im not a designer --I don't buy a dog and bark myself.


Here we go with the brick wall.

 

I am really curious about this phrase, and am not sure that I got it right. Can you elaborate it a bit more?
Why do you think designers are a ruin of boat building industry?

 

You have me curious now, Frosty. Can you supply a link to where you've posted info about what you're looking for? Are you still interested in pursuing your idea, scaled back to a size that would fit your budget?

 

Design something different!!!! Something that some one might like --something that does not look like the one next door.

Here's a novelty a boat that an owner wants.

What about a light weight cat thats capable of 50 KTs weight just 6 tons all in with twin 250HP all wipe clean alluminium formica surfaces with interior like an airbus 380 removable washable replaceable, ( I dont want wood im sick of wood).

Hull solid glass with ribs where necessary. Toilets in light weight stainless ( not ugly 50 year old ceramic heavy pot.

Propulsion system that lifts from the water.

Flat deck no windows for the hot climate. get the idea.

Come on something new!!!!!!!!!

 

What is the target size of the vessel, n° of berths and desired on-board services?

 

I had a designer from Australia knock me up a full drawing of what I wanted . When I saw it I was shocked , he had engines under bunks mid ships and bedrooms off bedrooms. It was the total opposite of what "I' asked for. It was pathetic. It was like he had not listened to a single word which is were I suppose I have got my disgust for designers.

He knew better than me about what I wanted and knocked me out a similar boat he had in production

I would be looking at 40 feet plus with 3 sleeping rooms and 2 bathrooms. Engines aft and out of the way NOT under bunks. Probably surface drive removable from the water (a must)

The interior would be very special like an aircraft.

Light light light. I know it has to be light.

But times have moved on Im not as young and financial situations have changed.

I will search for my thread of years gone.

 

Here it is ,--- Im sorry my criteria has changed a little as it a while since wrote this. And it is only 1 year ago and not the 3 that I thought it was.

I hear you about not being in the market as a custom design client anymore. You're still an interesting market research data point, though. I don't see myself designing this type of boat anytime soon, though I was part of designing the Krogen Express (then a 49, now lengthened to 52), so I have some related background.

I'd be interested in knowing if anyone is doing designs that appeal to you. If you can overcome that designers disgust you, you might enjoy watching this online: http://www.proboat.com/pechakucha-2012. In concept you're idea of going to an Australian designer for a power cat was not a bad one. Australia and South Africa have become creative incubators of power catamarans. Fast ferries more than pleasure vessels have driven power catamaran technology.

You're probably aware that this guy's there in Thailand: http://www.amdesign.co.th/. He's one of the 2011 Pechakucha presenters.

Have you ever visited the Moose Boats website: http://www.mooseboats.com? But you want something more aerodynamic...

 

Frosty,
Don't know what you've been told...but to get 50knots you're really going to have to go for the300-350hp range, like the Yamaha V8 5.3L.

So the engine and fuel package will be top around 2.0tonne..and that's only 50knots for just over 1 hour or running....these are thirsty beasts however you look at them.

The structure would be nominally 2.0tonne....which only leaves around 2.0 for everything else...no wait 3 berths, say 2 people each that means roughly 0.5 tonne...then their effects so another 100kgs...so that leaves roughly 1.5 tonne for everything else. A tall order indeed.

So for the hull, to gain back some weight, you would have to go with a carbon fibre hull to keep this weight down and get the required strength. That is not cheap at all...way more expensive than ally. How deep are your pockets?

There is no such thing a light weight stainless steel. It is still STEEL. You have to look at the various options available and compare like with like. Again, the lighter and more robust, the more expensive the items is. Done this exercise sooooo many times designing fast ferries.

The problem with clients that want fast fast fast is that their aspirations of what they want on board is generally at variance with the concept of light weight.

Can it be done...yes. Can it be done that fully satisfies the clients SOR and their budget....that's the million dollar question and requires a lot more investigation, when at the extremes of weight, for speed. The 2 generally do not mix...longevity goes out the window too all for the sake of weight!
