Either the Dart 15 or 16. You will right the Dart 15 OK. Probably, if there is enough wind to capsize you, there will be enough to help you right the 16 solo. The Dart 15 has a great fun racing circuit and can be car topped. If you can find a good second-hand Catapult, it is also very easy to right. If it is in good shape, don't let the inflatable hulls put you off. It is a very fast cat and great fun singlehanded. On flat water, because of its good pointing ability, it can hold a Dart 18 upwind. Very light also - for pulling up a slip or beach.
