Thanks Norm and Mark,
Here are a few shots. The row boat weighs ~175 lbs. so I took "bilge keel", photos from another boat already on her back.
I see bilge keels on boats that get hauled on the bank often and also powered boats more than nonpowered. They are placed at the turn of the bilge, hence the name. Sort of sacrificial protectors. They also help trap some water and cause the boat to lift and plane more easily when under power and they would give a sailing boat more laterial stability and keep her more "close", winded which allows the boat to point closer to the wind and slip sideways less.
Thanks again for the info,
Reid
