There are very clear rules. First: Dubrovnik had the right of way but also the obligation to stay on course. Second: Scooter did not have the right of way and should have changed course in order to avoid a collision. At the end Dubrovnik, who clearly had a better understanding of the situation should have reacted much earlier. But to blame for the collision is Scooter.
En mer, entre deux voiliers, c'est celui qui reçoit le vent sur son tribord (droite) qui est prioritaire......En l'occurrence, Dubrovnik était prioritaire, je pense qu'il a viré de bord pour tenter d'éviter la collision, mais trop tard.....
If you look closely and take into account the bad angle, it seems like Scooter was trying to duck behind, which he is obliged to do. Dubrovnik should have stayed on course, but it’s understandable if they thought a collision was imminent. However, it’s strange that Scooter didn’t turn to port after Dubrovnik tacked, as there seemed to be plenty of time to react.
