New Boat Design: "Velocity"

Come to Tassie and talk to Incat, who built and designed 3 Hales trophy holders, including the current one.

They need a new boat contract for you to practice with though.

 

Great Idea!

That makes sense...maybe they'll understand best what I'm trying to do...

I do agree though some of the Hydrolance Tech. claims like "zero pitch and roll at any heading" sound kinda outlandish (where is the energy of the waves going then?) as well as others. But overall I think the concept has much merit. Basically, a HARTH ship (as I understand it) is basically a really extreme version of a catamaran design. I believe that it can be done...otherwise they wouldn't have put the hours of thought into it like they have to make a website and a video demonstrating the concept. Heck, they wouldn't have formed the company at all if they didn't know what they were doing!

 

Oh well, don't take it for granted: http://www.fuellesspower.com/

 

daiquiri, Here they are still marketing those plans for that engine. What a scam.

 

Well that does it- I'm tearing out those Cummins and throwing in 20 of these and no more diesel for me.

 

haha - love these guys (or guy).

 

Could be an oportunity for TKOUSA here, free energy and perpetual motion is what the world needs more than anything these days.....

 

There are some very good collections of logical fallacies you might want to
consult. For example:

Have fun!

Hi guys,

Sorry I haven't been on. I have been looking over the HARTH site over and read through 'most' of the design information presented on the site.

I've come to terms that some of the claims they are making don't seem to be backed up with substantial engineering data that proves that the technology works. Boats and ships will always be 'moved' by the ocean in some way (otherwise where would the energy go?)

Could you guys explain to me a design which 'could' work in theory to design a craft such as my HSC Velocity that does incorporate 'some' aspects of a HARTH design?

 

Start by playing around with Michlet and the optimisation module GODZILLA.

That should give you some idea of the resistance of thin, slender hulls.

 

Thank you Leo for the program link.

I'm still going for my distant 'Project Velocity' ship to capture the Blue Riband speed record, but in a way that is realistic, safe, and economically viable.

I don't think the HARTH concept is dead, but needs to be surely be brought down-to-earth and made into a realistic design :/ Isn't it technically just a really slim catamaran? (at least that is how I see it)

 

To me it doesn't seem like you are doing anything of the sort.
Firstly, you don't even know what the speed record will be by the time you become a ship builder/NA.
When is this fantasy going to become reality? 10 years, 20 years from now?

It's an exercise in marketting claptrap designed to trick "investors" (aka suckers) in parting with their hard-earned money.

Here's a real (ie extant) fast boat that you need to beat.
Their speed of 58.1 knots was set last week and could be bettered soon when they reduce the weight a little.

Note that it is real, not some wanky fantasy drawing.

 

What an ambitious project! I admire your courage first~
The Destriero is designed by Donald L Blount, a famous hydrodynamics expert in US. That is a semi planing boat, which is the perfect type of hull for really high speed, with water jet and turbine engine. As I know the best speed for water jet is about 40~60 kts, and i'm not sure it would work in the best performance at 70 kts. And Leo‘s right，CAT is not suitable for such a speed, even the WPC type.
Anyway, it's good to take a shot.

 

Ok. Let me explain. Right now, I'm a freshman in community college doing my basics in AutoCAD, looking to transfer to Texas A&M University - Galveston to study marine engineering tech. This will be fall of next year (2014).

I know that the speed record 'bar' will be higher by the time I am ready to work with naval architects/marine engineers to design 'Velocity', if I chose to do so. But I still think it can be attained. As I said in my post yesterday, I don't really trust HARTH anymore -- I haven't seen anything more than sketches (drawings) and some engineering claims which are questionable (to me). I have emailed Walter Reed, but I highly doubt he will answer my emails anymore (Last time I emailed them, they called me 'some punk kid' trying to steal their design information).

If their technology was so 'revolutionary', why isn't it here now? Why aren't we seeing passenger ferries/cruise ships being built to HARTH designs, if they are superior in design?

About the 58-kt INCAT ferry, that's a very interesting article to read. And I do agree that it is here now, ready to tackle the 'Blue Riband' challenge if the company chooses to do so.

By the way, have a look at this, I found this site this morning. It's a contender for the Blue Riband (and 3 other challenges) very similar to a HARTH ship. http://www.atlanticglider.com/. This is a project that is real, not made up fantasy as HARTH supposedly is (but I do agree with you guys on most points).

 

The OP can get a good start with some most relevant information from the book: Hydrodynamics Of High-Speed Marine Vehicles, by Odd M. Faltinsen ISBN 978-0-521-84568-7

There is enough technical stuff in that book to challenge ones highest ambitions. It is almost complex enough to cause one to contemplate a change in career paths, say.... to plumbing or basket weaving.

That said; Why do we want to do a Transat at 70 Knots? Boeing, Airbus, and several others have already bested any conceivable waterborne record.

Speculation: Finding a partially submerged container at 70 kn would surely spoil a perfectly good day.
