Hiya Larry, My M17 rudder is in my downstairs office. Here are some quick dimensions. Height: 71.75" Thickness: 1.25" Foot width: 10" Stepped leading edge width: 11.5" Width above leading edge: 9" Width top of rudder: 6.75" Height from foot to leading edge: 25" Of course, the rudder is contoured (faired) for its fin effect through the water. Hope this helps. Later, Bones ___________________________________________________________________ Speed up your surfing with Juno SpeedBand. Now includes pop-up blocker!
