Vessel Positions | Vessel Clearance | Tides and Traffic Volumes | Commercial Reservations
Older vessels and aging terminals means we have to take a look at each truck that comes through the tollbooth to prevent damage to the deck and terminal surfaces. Due to these issues, WSF requires trucks with a gross vehicle weight of more than 80,000 lbs and/or 8'6" wide to have "travel approval" before crossing any of our routes.
When to contact WSF
- When your Gross Vehicle Weight (GVW) is more than 80,000 lbs.
- If your vehicle is more than 8’6” wide
- When your vehicle's ground clearance is less than 14”
- For commercial reservations to and from the San Juan Islands and on the Port Townsend/Coupeville route
Please fill out our Oversized/Overweight Vehicle Travel Request Form (pdf 82 kb) and fax it to us at 206-515-3846. If you are transporting a modular home, please also fill out and fax the Modular Home Measurement Diagram form (pdf 16 kb). Please allow two business days for processing. You can contact us at any time for status updates at 1-888-808-7977 (WA & BC).
For oversized/overweight annual renewal requests please note: yearly renewals are not automatic. Terminal weight restrictions have changed with new engineering data. Some renewals may not be approved.
Vessel positions are often described as "1" or "2." In general this means the first boat out in the morning is in the number one position. Two then, is the next departure. Where there are more than two vessels assigned to the route, more positions are added. Fauntleroy/Vashon/Southworth has three vessels, hence three sailing positions. Anacortes/San Juan Islands/Sidney, B.C. has four vessels assigned to the route and five during the summer schedule.
The position number will tell you which vessel is sailing at what time. Schedule pages have numbers beside the departure to let you know what vessels are assigned. This information is updated daily.
Why is this important to know?
Vessels have different clearances and depending on the height of your truck, may or may not be able to accommodate your load.
Vessel clearances range from 13' 6" on the Klahowya and Tillikum to 16' on the Chetzemoka, Salish and Kennewick.
Tides and Traffic Volumes
The Vashon Island and the Port Townsend/Coupeville routes have concerns with tides. Trucks destined for Vashon with less than a 14" ground clearance may have trouble driving on and off the vessel at certain tides. Tidal conditions often cause the cancellation of sailings on the Port Townsend/Coupeville route. WSF will publicize the dates and times these are in effect.
All docks have a high volume of commuter traffic at certain times of the day, generally eastbound from the islands and peninsulas in the morning, and westbound in the afternoon and evening. It is not possible to handle oversize loads during these times; WSF encourages truck traffic to travel in off-peak times. The Washington State Department of Transportation publishes a Commercial Vehicle Guide (pdf 1.4 MB) and lists curfews on highways for oversized rigs. These are also in effect for Washington State Ferries. For more information, visit WSDOT's Commercial Vehicle Services.
WSF offers commercial reservations in the San Juan Islands and on the Port Townsend/Coupeville route. See our vehicle reservations FAQ (pdf 433 kb) for more information.
