Has anyone ever considered or actual modified their rigging i.e. larger sails, taller mast, longer boom etc. I own a cherub. 25 1976 and wonder why a boat this light with a non-"blue-water-keel" can't go faster than an average of 6 knots. I'm not a marine engineer and I have found out that John Cherubini was a talented one, however, he most likely erred on the side of safety as this is not a racing boat. Any thoughts, recommendations, anecdotes appreciated. Sam
