Force 5 Wind Can Be Tough
Rémy is navigating the Raz de Sein alone in Force 5 winds and genuine offshore conditions.
Every decision matters in this demanding passage.
This training exercise takes place in one of Brittany’s most challenging boating areas.
The Raz de Sein in France, is famous for strong currents, confused seas, and rapidly changing weather.
Throughout the crossing in Force 5, Rémy continuously assesses the sea state and adjusts his course.
He manages speed, anticipates swell patterns, and maintains safe boat handling.
Most importantly, he makes every decision independently while keeping crew safety as the highest priority.

How is a rough sea named? Check out my article on this matter: Wind, Waves, Swell: Beaufort vs Douglas Sea Scale.
I truly value Olivier’s training, which is why you’ll find an extended collection of videos on RIBsONLY.com, focused on mastering navigation in agitated and rough seas.
