Maintaining Crabber/Towboat Lane Agreements
Conflicts between ocean-going tugs and commercial crabbers in Washington, Oregon and California were a major problem in the late 1970s. Crab pots fouled tugs as they moved between coastal ports, and the loss of their gear was a severe economic loss for crab boat owners.
Sea Grant programs on the West Coast helped broker an agreement that provided navigable towboat and barge lanes through the crabbing grounds between Cape Flattery and San Francisco. Washington Sea Grant took a leadership role in the late 1990s that remains pivotal in saving these industries hundreds of thousands of dollars each year.

For your convenience, Washington Sea Grant has made available electronic data files for commercial crabber and towboat towlane charts. Nobeltec data comes in a single text file; the other two formats entailed larger files, and so we compressed those into two different formats for downloading. Note: Please note lane change information for Cape Alava above.
- The following links provide access to data files; depending on application, they will be binary (e.g., .zip or .sitx) or text (i.e., .txt). You must download the appropriate file (Maptech, Nobeltec or WindPlot), decompress if it is a .zip or .sitx format, and import it into the appropriate program.
- Most contemporary operating systems come with file decompression applications, enabling the downloaded file to either open automatically or open upon double-clicking it. You can also obtain a version of the program required to decompress these files online (some are free; others are fee-based).
- Color key: blue = summer-only lanes; red = advisory only lanes.
