It is needed
The 75 models of the Oday 25 are set up a little differant than later years. The crank is required because the cable (stainless steel) is attached close to the pivot point on the centerboard, requiring a lot of effort to raise it. Later models have a line, (not ss cable) attached closer to the base of the centerboard, requiring much less effort to raise or lower it. Inside the stanchion post is a fiberglass tube that guides the cable. This tube also keeps the opening to the centerboard above the water line, thus keeping water out of the boat. I have thought about trying to set mine up like later models, but have decided that it is not worth the effort, I don't do much inside except sleep and eat if the weather is bad.Tom
