    Hey guys,

    Back on the boat design forum. yay :)

    What do you guys think about this design concept for ships/boats?

    The concept is called HARTH - which stands for High-Aspect-Ratio-Twin-Hull.

    http://www.behance.net/gallery/HYDRO-LANCE-HARTH-TRANSOCEANIC-HIGH-SPEED-SHIPS/607980

    I've started a design project for a boat to circumnavigate the globe, called project "Velocity" using this HARTH technology. She will be the fastest ship in the world, ever. A ship with no rivals. Like my project on Facebook if you're interested. http://www.facebook.com/#!/pages/Project-Velocity/470067196339328

    Similar concepts have been proposed including having actual vessels built and tested, some by other participants on this forum.

    The video you provided the link to as well as the Hydro Lance Corporation website http://www.hydrolance.net/ could form the basis for an interesting assignment for naval architecture students: Review the claims made and comment on their plausibility.

    Best of luck, but I think you are wasting your time with this junk.
    Search for Harth on this forum and you will find several previous discussions.

    the video lecture on the site looks quite old, at least 30 years based on the computer on his desk and his hair style. So after 30 years the only thing they could sell is a few passenger ferries? There must be reasons why this concept is not in wide spread use by now.

    Has anything been built to their designs beyond small models? You may be giving them too much credit.

    It is gobbledygook nonsense.

    That HARTH site looks like sketches a 12 year old would make while daydreaming in class. I sketched tons of planes and cars as a kid. I wouldn't try and build any of them.:p

    Sadly style over substance is the order of the days, in this super-connecting superhighway blogosphere of cut and paste and WOW what fancy colours, day and age :(

    The squeaky wheel gets the oil... :eek:

    I kinda see what you guys are trying to say...but I still hold faith. As per the video, I'm quoting here "Development of any resource is constrained until its elements are understood." Basically, I'm trying to say that current boat builders and desginers are reluctant to try new, potentially untested designs because they're accustomed to older, less seakindly designs. I also read some of the comments by some of the engineers/architects on this forum and see what you guys are trying to say as far as engineering/design goes. I truly do have faith in the technology, I truly think that development of the conventional monohull/multihull has reached its limit as far as seaworthiness goes. According to the website, ALL speeds for conventional ships are rated in calm water, not eleveated sea states/ Nowhere else can you see a vessel capable of 60 knots or better in above Force 6 sea states. Also, if there are any ship design economists on this forum, might you at least read this page from their website? http://www.hydrolance.net/page9.htm I think its well worth the read, and (for me at least) made me truly see the merit of HARTH ships over conventional ships (as far as economy of operationgoes). Wow, that's a mouthful ;) Please leave me some comments.

    OceanLinerFan: In your first post on Boat Design Net you mentioned you are starting college in the fall. Will that be in engineering or a similar technical field, or something else?

    The Hydro Lance folks make many extreme claims but they appear to have actually demonstrated almost nothing. (Any thing other than a small scale model?) And they have shown very, very little actual analysis, and what I have seen are very simplistic and generally rely on assumptions which are questionable at best.

    Various configurations of high speed catamarans with thin and/or submerged hulls have been proposed and analyzed. A number have been built with varying degrees of success. None have demonstrated anything close to what the Hydro Lance folks claim.

    Says who..and what evidence do you have top support this claim??

    Science & Engineering is not about faith. It is about cold hard facts which can be independently verified by anyone. Faith is for the religious..
