Cabotage laws restrict domestic-trade voyages (loading + discharging within the same country) to nationally-flagged and/or nationally-crewed vessels. This affects which seafarers can work coastal, offshore-supply, and short-sea routes in each country. Enforcement varies substantially.
This directory covers the 20 major cabotage regimes affecting a seafarer's ability to work coastal, ferry, and offshore-supply trades.
