A starboard tack in sailing occurs when the wind blows over the starboard (right) side of the boat, causing the sails to fill on the port (left) side. In this position, the vessel has the right of way over a boat on a port tack. Starboard is the right side, determined by facing forward.

Key Aspects of Starboard Tack:
Wind Direction: The wind comes over the right-hand side (starboard side) of the vessel.

Sail Position: The sails/boom are located on the left-hand side (port side).

Right-of-Way: A boat on a starboard tack is the "stand-on vessel" and generally has the right of way over a boat on a port tack.

Safety Rule: While having right of way, the sailor on a starboard tack must still act to avoid a collision if necessary.

This rule applies to all points of sail, including when navigating downwind or using a spinnaker.
