Full keel in reverse is no fun. Not just docking, but using a stern-tie.
I like a fin keel with a skeg rudder. Even then I have had rudder damage hitting a log off Powell River with that set up.
There is also the view that a full keel boat can be careened, while a keel cannot. I seen a photo of Bagheera, the Copeland's Bene 38 careened when they were doing rudder repairs. It probably depends on the boat.
