New NCA: The Commonwealth of Puerto Rico

Notification of Welcome - Announcement of the Commonwealth of Puerto Rico formally joining the WORLD COUNCIL as the newest NCA

World Council Members:

I, Fred Rocha, serving as Chairman of the Executive Committee am proud to announce the completion and approval of the application process allowing Puerto Rico to become the IOM ICA family’s newest National Class Association. I am hoping that you will extend your support and welcome to all their participating skippers at upcoming international events. Puerto Rico is excited about promoting their internal growth of the International One Metre, and views this inclusion to our World Council as an important step in formalizing their domestic and international participation now and in the future. Formal PUR NCA contact information will be added to the website shortly, so please help me to make them feel welcome by extending your greetings and support.

A welcome from the IOMICA Chairman

Welcome to the website of the International One Meter International Class Association (IOMICA). I hope you will find our resources useful and welcome you to explore our upcoming championships.
-Fred Rocha, Chairman

2022 IOM World Championships - Postponed

Due to the ever changing travel restrictions around the world it continues to be challenging to ensure that all NCA members are able to attend the proposed world championship in April 2022 at Rogoznica, Croatia.
As a result of the continued travel restrictions in place on some member NCAs the decision has been taken to postpone the IOM World Championship until later in the year.
The championship will now take place in Rogoznica, Croatia 27th October 2022 - 4th November 2022.
Please note a further review of travel restrictions will be held prior to confirmation of the event taking place.
-Rob Walsh, VC Events
