About Port of Vashon Island

This marina is located on Vashon Island in Puget Sound, Washington. It serves as a small harbor facility for recreational vessels.

Background
Vashon is a census-designated place (CDP) in King County, Washington, United States. It covers an island alternately called Vashon Island or Vashon–Maury Island, the largest island in Puget Sound south of Admiralty Inlet. Before the construction of a tombolo built in 1913, Vashon Island and Maury Island were connected only during low tide; now they are considered a tied island.
