    I'll look for it, but just in case can you post a direct link?:)

    EDIT............
    12 minute video:
    http://www.hydrolance.net/HARTH-EarlyTestVessel.htm

    Did Dan Rather and CBS get their cut?;)

    EDIT-2
    The less than one minute part of the video showing working model was too small and brief to be of any value to me.

    It's also hard to determine if the craft pitching seen is because of the chase/film boat or the hydolance performance.

    The aerial view of the chase boat and Hydrolance was so small and brief that no conclusions could be drawn (by me).

    The reto look and feel of the video reminded me of old ****, not a good impression but a lasting one.:D

    Well, "a breath of fresh air" - someone who thinks. All HARTH vessel incorporate a low energy and very effective surface wet-ted drag reduction system. Accordingly, your assumptions of skin friction drag are incorrect.

    If your company has come up with a novel and effective way to reduce skin friction drag, that in itself would be a huge breakthrough in naval architecture. Why don't you forget about the super thin catamaran stuff and just market the skin friction reduction element of your design? Just about any vessel that goes over 10 knots would benefit from a reduction in wetted surface drag. You could be sitting on a goldmine.:D

    After this many months I think it's safe to say the guy's given up on trying to convince us that it works....

    I think the closest real example to HARTH ship would be Turanor PlanetSolar.

    Thanks for an update on an old thread.

    Yep, like I said back in 2008, other people doing similar things beat this hydro guy to the punch (page 2).

    Gotta love the dreamer, makes life more interesting.

    That "Ghost" vessel resembles the original "Sea Shadow", except for the adjustable pontoons/struts & cavitation parts. Both are still SWATH vessels with their pluses & minuses though. What I question in Hydrolance concepts is that you would either need the craft to be as light as possible or thin hulls to be long & solid enough, both are limiting the use of such concept & it's feasibility. :p

    Though this ferry looks interesting: http://www.hydrolance.net/Common/hydfery5.jpg

    What a ridiculous bit of overindulgence. Lets see, 4 supercharged engines, because you know you can afford it and typical British over engineering is required. The hull forms are being kept secret, so who knows what's going on. The yacht's spec's are also seemingly secret, so, yeah and bunch of crap, until they fess up to what it really is, particularly with it's 7 digit+ price tag on a 24' boat (not counting it's ski's). Looks like a nice ride on a barely mussed up puddle, how about some real chop.

    Apparently it's not a super yacht but a super sport. From their page:

    "For true exhilaration seekers, why not unleash the 3400bhp of the Hyper Sports version with sub 3.5 seconds 0-60 acceleration and top speed over 96+knots."

    Yup yup.

    It's like someone saw the Skoota, which is practical (and practically free by comparison) and like Genie whilst dressing up Aladdin said "not enough" ... all the engineering is their version of the "birds that warble on key" etc.

    That said, it wouldn't be that hard to get a Skoota-like craft higher up bridge deck wise (just not that high up!) on longer hulls and still spend a fraction of the price while having a decent cruising speed and economy.

    Edit: you know, I always loved the '60s era Holiday House Geographic trailer home ... That body style would work nicely with some modest stylish stilt legs and long catamaran hulls....
