In the late 1970s, conflicts between oceangoing tugs and commercial crabbers became a major problem in Washington, Oregon and California. Crab pots fouled tugs as they moved between coastal ports, and the loss of gear created severe hardships for both commercial crabbers and towboat operators. 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, Washington, and San Francisco.
Since the late 1990s, WSG has led this process, maintaining the industries’ cooperation and saving them more than $1 million annually. WSG continues to hold two negotiations each year, improve electronic towlane charts and evaluate the project’s economic impacts.
