What type of vessel should avoid impeding a seaplane on the water?

Seaplanes in the water have specific navigational rights and require clear space to operate safely, especially during takeoff and landing. Any vessel that encounters a seaplane should take care to avoid impeding its movement. This is consistent with the fundamental principles of the COLREGs, which emphasize the importance of keeping safe distances between vessels, particularly in situations where the maneuverability of some vessels—like seaplanes—is significantly impacted by proximity to other craft.

While it may be considered good practice for certain types of vessels, such as fishing or commercial vessels, to give way, the regulation extends to all vessels on the water as a general rule. This ensures a uniform standard of safety and efficiency in navigation, preventing accidents and ensuring all vessels can operate without unnecessary interference. The requirement applies universally, reinforcing the need for awareness and consideration towards all vessels in the vicinity of a seaplane on the water.
