Yes. A canting rudder makes sense on a hull that heels about its design centreline, but separate rudders are needed for sled hulls that...
Nic pics, Michael. I take your point about tracking straight on autopilot. But I reckon the switch to twin rudders was triggered by the hull form....
I think I have a better feel for the systems now - Aqua Quorum and the current Vendée and Volvo boats are sleds with a transom-hung rudder and a...
Thanks, Michael. One of the things I want to chase down is canting keel patents. Pete Goss's description of Aqua Quorum's keel system in his book...
Thanks, Richard. I started with wikipedia, and I have Pete's book. I hadn't thought of asking Pete directly. I'll do so.
Does anyone know where I can find out more about the design of Aqua Quorum, Pete Goss' 1996-7 Vendée Globe boat? I'd particularly like to know...
Thanks, Doug. I knew you would chip in if I waited patiently. I'm not entirely new here - a few years ago I was learning from the Downwind Faster...
No. That's the one I meant. She seems to start rising onto the foils, then pitches nose down.
Not sure whether I'm allowed to make a second post on my own thread when no-one has yet responded. Should I edit the OP instead? Anyway, another...
An amateur video of the recent pitchpoling of Oracle's AC72 shows that her bearing off manoeuvre started off fine, with the bows up, but then they...
...publishing also helps if you're ever likely to commercialise something derived from what you're doing, even in a very small way. Stops anyone...
Thanks, MattZ. Can anyone post the equations for the reactions that take place?
1. If you want to build a hull like this with a thin skin that does not 'pant' between stringers & frames, make the frames curved, not slabsided....
