🔍 Key Concepts

• Boundary lines between Inland Rules and COLREGS (see 33 CFR Part 80) • The definition of Inland waters vs. waters outside the demarcation lines • Whether special items like pilot rules or fishery rules replace or just supplement the Navigation Rules

💭 Think About

• Ask yourself: Is the vessel inside or outside the COLREGS demarcation line at Race Rock Light based on the information given? • Consider which set of rules (Inland or COLREGS) applies by default in that geographic area before adding in any special local requirements. • Think about whether pilotage requirements or fishery regulations are usually the primary “Navigation Rules,” or if they are additional regulations on top of the main rules.

✅ Before You Answer

• Verify on a chart or reference where Race Rock Light lies relative to the Inland/International demarcation line in Long Island Sound (33 CFR Part 80). • Confirm which ruleset (Inland or COLREGS) applies seaward of the demarcation line and which applies landward. • Check whether local pilot rules or coastal fishery rules normally replace the standard Navigation Rules, or simply add extra requirements.
