    Twin flapping tail propulsion HPB

    Ah, but a tuna does not move its fin in a 2-meter sweep without a body and without a fixed pivot, which is more like what I'm going for. I am...

    Twin flapping tail propulsion HPB

    Um, this I don't get. Whose stroke? Conventional oar? Rigid fin? What sort of foil shape? Flexible fin? How flexible? Are you trying to plane, or...

    Twin flapping tail propulsion HPB

    Well, that's discouraging. I see how the transition at the top and bottom of stroke would be unlikely to provide much useful lift/thrust. What is...

    Twin flapping tail propulsion HPB

    Good point. :o). I like the shaft idea--but why a paddlewheel and not a prop? Not that I love props--I don't--but paddlewheels are pretty crude, no?

    Twin flapping tail propulsion HPB

    Nice-looking boat! I can see the advantage of a paddlewheel over a single foil flapping on a horizontal axis, or a vertical. I'm convinced two...

    Twin flapping tail propulsion HPB

    Well, maybe, but a few considerations are that a) I'd like to try flexible rather than rigid foils, so two "reversible" leading edges wouldn't...

    Schmidt Wave Propellor

    CImanges- I attached a short writeup of my idea to the similar thread "Twin flapping tail propulsion HPB." Attached here as well. It looks like...

    Schmidt Wave Propellor

    Hi, Curtis-- I looked at some of your (very) old threads, and it seems we share some interests in very unconventional designs and ideas,...

    Pivoting sponsons/pontoons

    Actually, another analogy that comes to mind is a snowmobile. Right? It's a three-point hydroplane, it's just that its "hydro" is frozen into...

    Barry--YES!!! That is EXACTLY what I'm after!!! Thank you! Especially around 3:16, where they have a runabout version. Four pods, out on booms. So...

    Kayakmarathon--Thanks for your input! As my response to BlueBell indicates, I was initially envisioning a big, seagoing trimaran (not that I could...

    Pivoting sponsons/pontoons

    Thanks, BlueBell--good input on damping and its likely effect on planing. In what way could allowing pitch- and roll- motion escalate impact...

    Pivoting sponsons/pontoons

    Bluebell--thanks for the welcome! As for the "roll" gain--one embodiment I'm considering is a fairly high-speed planing craft, such that the...
