So we have owned Dragonfly, 30-2 #25, for three years. She is an amazing boat. For our family of 3 she is the perfect cruiser. We've taken her on extended month-long cruses around Lake Ontario and the 1000 Islands and in 2013 she carried us around the Down-East Circle, 2200 nautical miles from Ontario down the St. Lawrence and the Maritimes to Maine and New England and back home via the Hudson and the Erie Canal. The interior layout is very livable.
This year we really clicked on the race course taking a bunch of flags in both regattas and Wednesday nights at the club.
In profile, the hulls look very similar, the big diffference being, of course, the outboard rudder on the -2. This makes the boat incredibly nimble and she is very well balanced with a 140 and main up to 15knots, then we dial her in a bit. I have raced in 35 knots with a 100 and reefed main, very solid.
