Endorsements that open doors

• Tankerman

  Required to handle liquid cargo. Tankers and fuel barges pay more, and this is why.

• Towing endorsement

  The separate credential for pushing and pulling barges. A whole industry on the inland rivers runs on it.

• Radar observer and electronic charts

  Standard for bridge watch, renewed regularly.

• Unlimited tonnage

  The difference between running a harbor tug and sailing as an officer on an ocean-going ship.
