At this time, experienced crew members will judge how to sail according to the movements of seagulls, so seagulls are called sea navigation safety forecasters.
When seagulls gather near rocks, reefs, shoals, etc., when the noise is noisy, it is a reminder that there will be a collision near the reef.
Seagulls have the habit of flying along the harbor. when they get lost in smoke while sailing at sea, they can usually find the port by following the direction of the seagulls.
If the seagulls fly close to the sea, it indicates that the weather is clear, and if they keep wandering along the sea, it indicates that the weather will slowly get worse.
