In crossing on open water, a fishing vessel has another vessel sailing on its starboard side. Which vessel is the stand-on vessel?

The sailing vessel on the starboard side.

The vessel that is not fishing.

The fishing vessel because it is fishing.

The key idea is how stand-on versus give-way roles are assigned in crossing situations, with a special provision for fishing vessels. When two vessels cross and one is on the other’s starboard side, the usual rule is that the vessel with the other on its starboard must give way. But there is a specific rule that a vessel engaged in fishing is treated as the stand-on vessel in such scenarios. This means the fishing vessel should maintain its course and speed, while the other vessel (the one on its starboard) must take early, substantial action to avoid a collision. So, the fishing vessel is the stand-on vessel here because it’s actively fishing, and the other vessel must yield.

If you’re wondering about the other choices, the sailing vessel on the starboard side would be the give-way vessel in this situation, since the stand-on role belongs to the fishing vessel due to its fishing activity.

The vessel on the port side.
