    When it comes to me all you know how to do is bullshit, Simon.

    Nonsense! On a Bradfield type foiler where the foils develop all the RM for the boat, the further away from each other the two main foils are the less load on both of them due to the development of righting moment. Major design element of such a foiler. And not a good system-or even a viable...

    Simon, your hijack of the A Class thread to start a bullshit conversation about me is disgusting. Your misrepresentation of what I'm doing or have done is just pitiful. When you are backed into a corner you always lash out-you've done it in the AC threads where you spouted bullshit and I called...

    Simon, I am involved and have been for some time-not specifically with the A class but with catamaran foiling. ----- Bradfield's foilers were oversquare trimarans and his system is suited to that particular type of multihull because using the foils for RM on a cat with a "conventional" beam...

    I think you are missing a fair amount of the picture. Read what I posted from Nathan O. Yes, you would save some money not having to make an L, but with the moth style system, the cost comes back with the control systems. Yes, there are some pretty simple wand systems out there, but, in a...

    Theres a bunch of small foilers under development from a cartopable foiler to a double/single hander to the Phantom -and after Cleans interview with Spithill- probably a foiler for Opti kids. Lot of excitement about foiling now. I'd say the A Class doesn't have much time to commit before it's...

    The lines on the sketch are just part of the illustration. With the boards partially down in the cassette the case is brought over and slides straight down until it locks. According to my cat manufacturer friend there is no structural problem-and I agree with him. I've built many foils and...

    The cassette system that I came up with would definitely be able to be installed "from the top"-no question about it. The downside, according to a cat manufacturer I've shown it to, is that there could be problems due to the proximity of the foil to the side of the boat. But there may be...

    Just discovered accidently that not only are the Paradox rudder foils reversible but so are the daggerboards-two foils in one-brilliant: http://carbonicboats.blogspot.com/

    ==================That is pretty damn cool-brilliant idea!

    ------------------Thanks Tom! Are the rudder foils reversible for light air vs heavier?

    Raphael, I think your development work is outstanding. The improvement from the first video is obvious. I wish you the best of luck-I think you deserve a lot of credit.

    All you have to do is look at the performance of the Hydros Nacra F20c, their new C Class, the Flying Phantom, the 45's and AC 72's to know exactly the right foil configuration and type to use. I don't know where the videos are here but on boatdesign.net they're in "multihulls" in the LAC 2013...

    For what its worth, Bradfields foilers are set up with the mainfoil at a nominal +2.5 degrees angle of incidence, with the trailing rudder foil at zero degrees-both set up relative to the static waterline. A characteristic of those boats is that the mainfoil carries 80% of the load and the...

    Here is the proposed rule change: Proposed Change to Rule 8.2 Chris Field has suggested a change to Rule 8.2 The current rule 8.2 states - Movable and retractable hull appendages shall be inserted from the top or be capable of being fully retractable into the hull. The BACCA are submitting...

    I wonder what Raphael's thinking is on having the tow line so low? The force moving the boat wouldn't impart any pitch down force(or very little) compared to the real rig forces.

    That reminded me: when Dr. Sam test towed foilers he put a stub mast on the boat and rigged the towline to the approximate vertical CE position up the mast.
