When float planes operate on water, what is a rule they must follow concerning other vessels?

Float planes operating on water must adhere to maritime rules that govern interactions with other vessels. The correct guideline indicates that float planes should give way to vessels that are on their right side. This rule aligns with the convention established for navigating watercraft, where vessels approaching each other are required to yield based on their relative positions—specifically, the vessel on the left (or port side) must give way to the vessel on the right (or starboard side).

By following this rule, float planes help to ensure safety and reduce the risk of collisions with other watercraft. It's crucial for pilots of float planes to be aware of their surroundings and the movement of other vessels on the water, as the dynamics of operating a plane on water can differ significantly from those in the air. Thus, maintaining situational awareness and adhering to the established navigation rules is key for safe operations.
