Medium-sized marina with multiple parallel docks packed with boats, adjacent surface parking lot with visible vehicles and some striping, situated on a bay shoreline with a few buildings.
Semiahmoo Marina is located in Blaine, Washington, on the northern tip of the contiguous United States, along the Semiahmoo Spit that extends into Semiahmoo Bay, a sheltered inlet of the Salish Sea on the Pacific Coast near the U.S.-Canada border. This marina serves recreational boating and sailing activities, catering to those exploring the protected waters of the Salish Sea, including opportunities for fishing and access to nearby islands in the Pacific Northwest region.
Marinas typically need to separate slip holder parking from day-visitor parking, trailer areas, launch ramps, and secure dock access points. Modern facilities use barrier gate systems to enforce these zones automatically — allowing permitted vehicles through via transponder or keycard while logging all access events.
