New IECA Class Rules in Effect

The final stage in the process for changing class rules, World Sailing approval, is complete and the new class rules are in effect.

The new rules are posted here and other technical documents here.

Each proposed rule change was designed to solve a particular problem, and was considered with particular reference to:

  • Performance and One-Design Control
  • Safety
  • Cost
  • Clarity for sailors, builders and measurers

The IGC, ODTC, and One-Design Project team thank everyone who supported this process.

Questions may be addressed to or to your local Fleet Captain, or to any of the IECA officers, who may be found at
