Rules of the Road · Responsibilities Between Vessels
Under Rule 18, which sequence correctly represents the hierarchy of give-way obligation from most burdened (must give way to all others) to least burdened?
- APower-driven > sailing > NUC > RAM > constrained by draft
- BNUC > RAM > constrained by draft > fishing > sailing > power-driven
- CPower-driven underway > sailing > fishing > RAM > NUC✓ Correct
- DFishing > sailing > NUC > power-driven > RAM > constrained by draft
Explanation
Rule 18 establishes the pecking order: power-driven vessels give way to all others. Sailing vessels give way to NUC, RAM, and vessels constrained by draft. Fishing vessels give way to NUC and RAM. NUC and RAM give way to each other only as required by Rules 13-15. Constrained by draft has the most limited give-way obligations.
