    ALBERG's NEW RUDDER

    Here's Ebb's copy of Alberg's new rudder shown in the A-C yacht's plan. For some reason, I can't get the photo to rotate. It's correct in my file, but it rotates when inserted into the post. Ebb writes:

    Rudder has a 1/8" G-10 'core'. It's the rudder shape andallows trailing edge to finish in something really tough. Two layers of veed meranti plywood, creating the essential shape. The blade is 2 inches at the post trailing to 1/4". NACA airfoils at 5 'stations' provide the dynamic curve along rudder length, which were actually very mild, as I used only the trailing half of the wing shape. Used thickened epoxy - and finished offwith Wet/Dry 700 Epoxy Paste (underwater epoxy) which smoothed well and provided a light color finish. Rudder lives underwater, underwater epoxy to finish. Splashed before the gudgeon was installed, and sitting in the mud at Spaulding the rudder has lifted out of the shoe and won't drop back in.

    Friends, Stay well, See you out there.
