Clearance

Customs and the locks

Customs

Reporting arrival

The NOAA Coast Pilot says Seattle is a customs port of entry. The US Customs and Border Protection list for Puget Sound boat arrivals names offices at Friday Harbor, Point Roberts, Anacortes and Port Angeles. Seattle is not on that list. CBP says all vessel masters must phone in their arrival to the office nearest their arrival location.

Licence

Cruising licence

19 CFR 4.94 allows a cruising licence only for a yacht of a country on its list. The yacht must not engage in trade. A foreign-flag yacht without a cruising licence must follow the laws for foreign vessels arriving at ports of the United States. Check the rules for your passport.

Locks

Hiram M. Chittenden Locks

The locks lead from Puget Sound to Salmon Bay, Lake Union and the ship canal. The large lock has a clear length of 760 feet and a width of 80 feet. The small lock has a clear length of 123 feet and a width of 28 feet (NOAA Coast Pilot 10). Lake Union Drydock Company says the locks take vessels up to 780 ft long with a 78 ft beam.
