Milton Thrasher: Wing keel for Irwin 23 modified

The plywood wing keel prototype has been moved back 8" to improve balance. The 1" x 6" board fits up into the centerboard well where a bolt through it at the centerboard pivot point and a bolt at the stern end into the lead keel makes it firmly attached but removable for more adjustments.
