Is it a lifting keel or a center board?? A center board is a relatively trouble free and easily fixed device. Lifting keels usually involve a lot more involved
hardware and structural issues. There can be an issue with breaking the board off in an accidental grounding or wear on the board axle. Neither has been an issue for me in the two center board
boats I've owned. Have run aground too many times and the only problem was once board jammed in the trunk by small rocks. A little
work with a screw driver prying out the rocks
solved that problem. For the most part have sailed with the board up so it's not an issue in grounding.
Own a center board boat and the only problems with it is the boat has to hang in the travel
lift slings to
paint the board and replacing the center board pennant. The first is no big thing for most yards, just lifting the boat at the end of the workday so you can anti foul
paint it the evening before and launch the next morning. Amsteel and other high strength lines make replacing the pennant virtually a non issue.
