Final answer:
The correct order of priority for vessels under the COLREGs, from highest to lowest, is Not under command, Restricted in ability to manoeuvre, Sailing, Fishing, and Power-driven.
Step-by-step explanation:
The question refers to the priority of vessels under the International Regulations for Preventing Collisions at Sea (COLREGs). The correct order of priority, taking into account the hierarchy established by these regulations, is as following:
- Not under command
- Restricted in ability to manoeuvre
- Sailing
- Fishing (if it is not trawling, which would make it higher in the hierarchy)
- Power-driven vessel
This order of priority helps prevent collisions and is used to determine which vessel has the right of way in a situation where two or more vessels encounter each other.
