Vineyard Haven Harbor


Over its 350 year history Vineyard Haven Harbor has been known as “Nobnocket,” Holmes Hole and by its current official name, Tisbury. Today, despite its increasing popularity, the island’s largest port of call with major year-round ferry traffic to the mainland remains a very sensitive part of our marine environment. It’s an important spawning and feeding ground for several species of fish and is an excellent harbor for swimming. It is critical to safeguard its health for all its users.



Since our founding in1989, TWI has worked feverishly to keep the harbor clean beginning with its initial project, spearheading the dredging of the inner harbor channel. We funded the first pumpout boat, installed a demonstration garden at Owen Park and wrote and published an informative brochure for arriving boaters, providing them with cultural options as well as where to find boating necessities and ways to help protect this special area.



TWI takes water samples during significant rain events at certain harbor locations to measure the level of pollution in the resulting runoff. This water testing gives valuable information to the Department of Public Works and the Board of Health. Currently, efforts are being made to mitigate the areas most affected by runoff by installing first flush catch basins and bioswale filtering ditches.
