I am only familiar with the 26.5 Hunter wing keel that weighs appx 1800 pounds. Did the 26.5 have a swing keel?
If you are referring to the Hunter 26 waterballast swing keel, it actually is a swing centerboard as the water inside the tank is the ballast. The board for intent purposes weighs about 90 to 100 pounds and thru a pulley system, that line is attached to the head of the centerboard. It is hard but in most cases with a umph and another umph, I could raise it by hand. However, it is easier to raise via winch and is up all the way when you hear the clunk sound. Never even think of adding an electric winch for that due to cost and possible damage if over cranked.
So, I am not sure what boat you have unless the 26.5 did have indeed a swing keel but not sure.
