    Concept reconfigured for outwards inclining wing tip foils deployed with rotational action

    Overall length reduced to 26' (opinions welcomed re pros and cons of such a move)

    Beam at the widest point now 3m. Reduced the number of chine lines for ease of drawing and sewing

    New pics. Foils not yet shown. Pics are only of the hulls inflatable fairing, aluminium pontoon insert not shown

    PC: yes, similar to a drone but with some advantages when used in water. There is very little, if any, hull friction went under propulsion, as any hull friction is used to propel forward. Less chance for entanglement with debris since it would be flung outward, and the draft is close to zero when compared to traditional hydrofoils. Could hydrocopters be more efficient and possibly faster than planning hulls if their design bypasses water surface friction and displacement hull speed Concepts ie. no need for long hulls? Maybe the existing control Concepts currently used with drones could be used? I have seen pictures of working models, but the concept might have to be developed so it works well in rough water.

    I believe I understand some of this. Do the rotors provide lift and forward propulsion?

    Yes, the individual rotor blades on the 4 rotors are tilted and bent at about the middle section so the outermost individual blade sections slaps the water flat providing forward thrust along the rotor's inner water contact side yet penetrating water just enough to provide lift for the whole vessel. The outside of the four rotors' blades do not touch the water, only the inside does.

    I understand now. It's a very interesting concept
