Preliminary simulation training for O2Y

June 24,2024(Mon.)

It is a practical training for athletes participating in O2Y, chartering a fishing boat in the sea area between Okinawa and Yoron and paddling downwind about half the distance of the course. How to navigate to Yoron Island? This is a great opportunity to test all the water quality, temperature, hydration, etc. in preparation for the strait crossing. Paddlers who are challenging channel crossing for the first time are required to participate.

本イベントは特別な安全規定のもと開催します。1月21日O2Y WINTERトライアル(サーフテクニカルレース)を経て選考します。毎年6月後半、梅雨明けの沖縄本島は大変蒸し暑く直射日光を浴びると体力はかなり消耗します。気象や外洋リスクを理解し十分な経験を証明できる方はトライアルを免除させていただきますので希望者はお問い合わください。(モロカイ-オアフ海峡横断経験など)



安全管理の観点から本番で使用する機材は申込用紙に事前申告が必要です。申告の無いボードを外洋ダウンウインドレースで使用することは認められません。インフレータブル の使用は安全面の観点から不可とします。

This event is held under special safety regulations. Paddlers will be selected after the trial race on January 21st. 

Every year in the June, the main island of Okinawa after the rainy season is very hot and humid, and if you are exposed to direct sunlight, your physical strength will be exhausted considerably.

Only those who understand weather and open ocean risks and can prove ocean paddling experience will be exempted from the trial. Please contact us directly. (Reference: for those who have experience of Molokai-Oahu channel crossing.)



From the safety perspective, all participants require to use equipment which they accustom to use for open ocean down wind race. A list of all equipment is required with an application. Inflatables is prohibited for safety reasons.
