Coloured pennants matching the class flag are to be flown from the backstay.

  2. have been issued a rating certificate by a North American PHRF station and have an equivalent rating on file at ECPA or,
  3. have been issued a one-design measurement certificate and have a one-desing rating on file at ECPA;
