Rules

One Design Class Rules:
The Dart 18 class is defined by a set of class rules. These rules prohibit ANY changes unless the rules specifically allow a change. This means that a 10-year-old Dart is the same as a brand new one and as a result holds its resale value far better. IDA plays an important role in keeping the Dart rules strictly one design by preventing changes and providing a measurement structure that maintains the one design.
