Winged Keels Pros & Cons
I have an S2 7.3 meter, shoal draft sailboat. I am contemplating attaching a "wing" plate to the aft bottom portion of the keel to increas upwind performance.
I am thinking of glassing this wing onto the bottom. The getting stuck part of this I worry about some, but with a 24'' boat, 3'' draft, I''ll bet I can simply jump into the water and push her off in many situations.
Design factors I am wrestling with:
- chord length
- leading edge angle for shedding debris
- core material
- overall width
- structural design
