If it was windy the bag wasn't required, medium winds rarely, light winds and drifters more often but not every time. The Dart was my first Cat so now with a little bit more knowledge i.e letting the downhaul off as well as letting the main and traveller out I would probably succeed in righting more often without the bag.
I used to say with the Dart 18: "If there was enough wind to cause a capsize - there was enough to help me get back up"
