Why cutters suit sanctions enforcement

Would the United States Coast Guard be better suited than the Navy to sanctions enforcement?

Yes. Anti-smuggling, boarding, and prolonged presence are built into Coast Guard ship design and operating practice.

Cutters are designed to embark multiple boarding teams and remain in an operating area for long periods. Those traits fit sanctions patrols, which require repeated inspections and maritime law-enforcement work. High endurance lets a cutter maintain pressure without consuming a major fleet combatant. The service is equipped to preserve the peace through patient enforcement.
