FAA Ground School Practice Test

When a seaplane and a motorboat are on crossing courses, which has the right-of-way if the boat is to the left of the seaplane?

1. The seaplane

2. The motorboat

3. Both are equal

4. Neither has the right-of-way

The correct answer is: The seaplane

In situations involving crossing courses between a seaplane and a motorboat, the rules of navigation dictate that the seaplane has the right-of-way if the motorboat is on its left side. This is based on the general principle that aircraft, including seaplanes, are typically given priority over watercraft in navigational contexts. The right-of-way rules exist to ensure safety in these situations where two different types of vessels may be on a collision course. Since the seaplane is actually at a higher altitude and moving through airspace, it is recognized as having more maneuverability and the responsibility to avoid collisions. Furthermore, when a vessel like a motorboat is to the left of the seaplane, it aligns with standard navigational practices, which dictate that vessels should give way to the right when crossing paths. Therefore, the seaplane retains priority in this scenario, helping to maintain order and prevent accidents in shared navigation areas.
