    From my observations, photography of boats in operation, is often akin to that of a woman who insists she be photographed on her "better side", for greatest effect. It is rare to see them running at angles to the waves that don't flatter.

    Alik,

    Have you investigated the history of Safehaven Marine? https://www.safehavenmarine.com/about
    I ask because they have been successfully building military vessels for years. https://www.safehavenmarine.com/vessels

    Should you so desire, you could contact Frank Kowalsky, but I suggest not until you've looked at the details of the voyage around Ireland & Rockall with Thunderchild https://www.safehavenmarine.com/world-record-attempt & the planned, but postponed Atlantic crossing with Thunderchild ll.

    OTOH, the distributor nearest you is Woori Oceantech,
    Naval Ship R&D Centre, 24-12, Noksansandan 335-ro, Ganseo-gu, Busan Korea 46754 https://www.safehavenmarine.com/distributors

    Email, wmmalala@wooriocean.com

    I have been on their boats at Southampton.

    Why You think I should contact their Korean distributor, for what purpose?? I am not a buyer...

    In which case they know you & if you want to see Thunderchild ll blast through following seas, check YouTube & ask Safehaven Marine to send you a video, if you can't find what you want to view. Being at the helm & surfing Thunderchild ll down & across the face of a huge following wave, would be intensely exciting & the ride could last for miles.:eek::cool:

    With a nose like that I'd call it "A Big W" just to see how many caught the reference.

    You know, if anyone ever wanted to knock down a bunch of buildings for some big public project (say a massive national hospital working along the lines of the old county hospital system ... because bus tickets to DC are not expensive compared to a stay at a local hospital for a planned-for procedure) they could choose to knock over all those law and lobbying firms and it would be a win-win. ;)

    Lets talk about that foredeck. It features what appears to be a big stocky crane.
    Is it for crab pots? Shrimp pots? Certainly not for a tender as there is no room for one unless you put it on the couch.

    Now, take this basic lack of comprehension and apply it to hull design and structures...

    There is a difference between a concept and a concept design. Yeah, a lot of automobile concepts just look cool. They just sit there, and people look at them, and manufacturers take the good/interesting/useful elements and integrate them into designs that do get built. It's not like he posted the scantlings and asked what boatyard could it build it, he just posted a (pretty well done) render and asked what people thought of it. Sure, be honest, criticize, but why be abrasive or condescending? This boatbuilding thing requires the union of mechanical/hydro/aero engineering, r&d, interior design, fabrication, marketing, sales, and finance, and no man is an island. At least he comes with something that is nice to look at, even if useless in itself. A far cry from someone who leads on threads with hare-brained ideas but not even a napkin drawing, or, worse, someone so secretive that they need design help without giving information about the design in question.

    I can see four advantages:

    1.) it would efficiently hose everyone on deck when it encountered any kid of a wave. One a hot day, they may appreciate this.

    2.) it would make anchoring a nightmare.

    3.) it may cut down on pitching when going into a head sea. But I think it may have to be sharper to do this, and

    4.) it may make the boat easier to maneuver in a cross-wind.

    Here's a completely wacky idea and one that folks will probably be able to quickly shoot full of holes. Well, more full of holes than the idea already demands.

    Keep the bow as the "real bow" but extend the deck forward a bit, extend a fake bow with slatted sides formed to direct water to the sides and down to match and then put a grill on the boat, one that helped feed water towards the sides to then be shed (probably much wider at the top). The key would be the shape of the inside directing water accordingly, not just a water catching void. Probably will need some ability to simply dump water straight down too to avoid it holding any weight of water from a big wave that couldn't be shed quickly. Not really a massive forward scupper to redirect water and throw it to the sides / down (which didn't look like a flared bow) but sorta that. Naturally the inside of the thing would have to be carefully shaped.

    I'm guessing the underwater forefoot (where there would be buoyancy) would end up being that much longer.

    Now, I'm not saying a chrome grill like it was some massive '26 Duesenberg Speedster A (though done right that could look nice and would definitely NOT be something already done on big yachts), just a way to have an "axe-bow" that handled water differently.

    I have now BS'd ... no unemployment drachmas from Bea Arthur for me this week.

    Interesting idea Rurudyne, but the '34 Chrysler Imperial Airflow is more old school axe bow. [​IMG]

    Actually, most US WWII submarines had bows like that. Go look at a Tambor, Gato and Balao classes. While there was a buoyancy tank in the bow, this LP tank is free flooding and only blown to surface the vessel. When running on the surface ("over one and under two") the water shed by this tank went through the deck gratings and out the casing vents.
