Vessel Guidelines
At the heart of every safe transit through Puget Sound lies clear guidance, expert oversight and high standards. These guidelines help mariners understand the requirements, expectations and collaboration needed to navigate our waterways safely.
Essential Transit Requirements
- These guidelines are advisory in nature and do not override the judgment of the Pilot assigned to the job.
- They reflect minimum standards for vessel class, tug arrangements, equipment and environmental conditions. Specific conditions may require additional measures.
- Mariners should always consult the latest published version and communicate directly with their Pilot or agent.
Key Planning Factors
- Tugs and propulsion. Vessel tugs and bow-thruster capabilities must meet defined ratings.
- Engine power and response. Maneuvering speed/RPM data must be posted and available.
- Clearance and spacing. Adequate space around the vessel, under bridges or overhead obstacles, and from other vessels is required.
- Weather, current and tide. These conditions heavily influence transit readiness and may trigger special measures.
Special Waterways and Terminal Zones
- Specific terminals and harbors (i.e., Seattle East Waterway, Tacoma/Blaire Waterway) may require additional tug packages, daylight transits or Pilot advance planning.
- For example, vessels over certain lengths or beams may require a second pilot or extra tugs, discussed ahead of arrival.
- Pilots will evaluate individual vessel characteristics (length, beam, draft, gross tonnage, etc.) and prevailing conditions before confirming transit.
Communication and Coordination
- Arrange pilotage 24 hours in advance through the vessel’s agent or directly with the Pilot dispatch.
- Monitor VHF Channel 13 (Pilot boarding area) and reaffirm estimated time of arrival as you approach the boarding station.
- Be prepared for boarding via Pilot ladder, rigged per SOLAS regulations, in designated boarding areas.
