SeaTac Marine Services is located on twelve and a half acres of waterfront property along the Duwamish River in central Seattle.


Our specialized high ceiling support building was originally built to construct ferries and can still be used for large boat building and construction. Totaling approximately 40,000 square feet, it is 400 feet long by 100 feet wide and 64 feet tall. It features 14 truck bays for loading and unloading. The building also has private offices, a built in crane and 2,000 amps of power available for your project and needs.

On the waterfront, our facility features 1,600 feet of dockage available for loading and unloading, short term and long moorage. Each slip has shore power available, water and 24 hour access, if needed.

We also have multiple forklifts of all sizes available for loading and transport, including 35 ton heavy-lift machines. Our barge ramps are capable of holding up to 56 tons.
