Hi Judy et al:
First of all, condolences on your recent mishap. As an accomplished oyster
bar basher, I share your pain. However ,since you are accomplished at
fiberglassing and embarking on a major repair endeavor, why not take it one
step farther and design, build and install a true swing keel. Lengthing
the keel slot to approximate the cabin headroom dimension would allow a
fully retractable ¼ circle keel that would pivot about a bolt at the forward
end. When down, the keel would be supported laterally by the trunk walls,
so flutter shouldn't be a problem. Properly weighted, such a keel would
allow some degree of retraction for improved downwing performance without
raising the CG to the extent that raising the current dagger board does.
Just a thought,
Mac Davis, Kelpie, WWP19#804, Aripeka, Fl

I'm going to
cutt out the keel trunk and glass in a new one designed like the one on
Jerry's boat. Last weekend I went over to Jerry's and measured all the
dimensions. The work will start right after our last PY cruise of the
season
on Nov 6-7 in Alameda.
