Not in any particular order, but 10: It was drawn by my favorite designer. It's very well built. It's mechanically straight forward. Everything mechanical/electrical/etc... is easily accessible. It's a great looking boat (to my eye at least) both in the slip and under sail... It's fast for it's size. It sails very very well in a wide range of conditions. The ergonomics of the cockpit and deck work well. It's very comfortable below for a racer/cruiser. It's easily sailed both crewed and short handed. It's a joy to both sail and work on... there. It's got '11'!
