Just posting this picture as a warning to those contemplating buying larger deep fin keel boats. The vessel pictured broke loose from its mooring after a storm and ran aground outside Staten Island's Great Kills Harbor. The keel snapped off after the tow boat attempted to move it. The bottom line is that these deep keels put tremendous strain on the hull while at the same time, their narrower point of attachment makes them less strong. Unless you are racing, there is a lot to be said for a shallow keel.
