Which vessel is the "stand-on vessel" when encountering a recreational powerboat?

When determining which vessel is considered the "stand-on vessel" when encountering a recreational powerboat, it is essential to understand the navigation rules that dictate the right-of-way laws. In this scenario, the large ship in a channel is recognized as the stand-on vessel. This is because larger vessels, such as ships in a channel, are generally constrained by their draft, and they must proceed with caution to ensure safe navigation within confined waters. As such, they have the right to maintain their course and speed in these situations.

The other options do not hold the same standing:

• A sailboat with the right of way is typically required to yield to the larger, constrained vessel.
• A fishing boat under 26 feet in length is often classified as a smaller vessel and would also need to give way to the larger commercial ship.
• A recreational powerboat in distress does not automatically hold the position of stand-on vessel; instead, it may require assistance and would not have the right-of-way in this context.

Understanding these rules is crucial for safe navigation and ensuring the proper granting of right-of-way, particularly in busy waterways where multiple types of vessels may be present.
