the rest of the keel is a standard 35 II keel its just the back of the keel was modified . the back of the keel feathers down to about a 1/2 inch. ....tom the new owner looks in on this forum perhaps he can tell us more if he reads the thread..
I have seen a picture of a 35-2 with the newer elliptical rudder change, but never one with
any keel change.
It would be interesting to view the plan/drawing for the change that was made and actually hear from someone that had sailed it before and after.
That's the sort of glass work that can cost a lot of hours, add some wetted area, and change the center of lateral plane.
Unless it were done by Bruce King, I would sure be reluctant to do something like that.
From another perspective, having viewed a late model Beneteau of similar size in the yard recently, the hull of the 70's E-35-2 with it's internal ballast looks absolutely Faster (!). The really FAT cast iron keel on the Ben. had huge amounts of wetted surface and frontal area.
