A friend of mine just purchased a 1989 Pearson 27. We took her for a sail the other day. She handles nicely but we kept hearing an intermittent hum, loudest in the aft cabin. The only electrical device running was his GPS. The diesel was not running at the time. Has anyone else experienced this? Is it possible it’s the Hydro dynamics of the wing keel?
