    I've been trying to decide the method to to mount the e-rudder on the boat, cassette, gudgeons/pintles, etc. Cassette seems like lots of work, but nails the deployment issue. Looking for other ideas, and sketched up the attached. I would like to hear from folks who have needed to actually deploy an e-rudder, if the sketch has any merit.

    Chris was showing me his recently-acquired carbon e-rudder today and I suggested it might be time to schedule another one of these:

    How about this May? That gives you three months to build or buy something and get it fitted, and it will still be a couple of months before LongPac.

    Here are some photos and comments from the show-and-tell (and race) two years ago:

    What with contemplating making a wood core rudder from stacked, glued wood 2 x 2's and then shaping with a router and a template, I've also been considering how I could use this technique to crank out a decent e-rudder. I strongly doubt that it will be ready by may, though.

    I've heard back from a guy in Texas who has a CAD controlled hotwire foam cutter. He can cut high density expanded polystyrene foam foils to use in laminating e-rudders. This is heavier and stronger stuff than what Flying Foam offers, now. He makes pretty big foam model airplane wings...like BIG model airplanes so I expect that he can crank out 6 foot long foils. Not sure on price but probably somewhere between $30-50 per foil.

    Is anybody interested in purchasing a foil to laminate up their own e-rudder?

    That twin tiller setup is cool.

    That's for sure a "kinda keep racing" setup. Very deep with 1" stainless pins.

    On the Bear Boat swing down rudder, it would seem to me that between the time that the rudder tip hits the water and the bottom bracket is pinned there could be a lot of torque on the weld at the gudgeon/pintle bar and the tubes running back to the transom? Did this pass an install test in some waves?
