Tidal Grid

Have a need to inspect the bottom of your boat or change out a zinc? Then consider using our Tidal Grid.

Built in 1975, the tidal grid is one of the last remaining in Puget Sound. It offers boat owners a unique opportunity to conduct vessel inspections without having to pay for a haul-out.

To reserve the tidal grid, please download and complete the Tidal Grid Reservation Form. Either email or fax (779-8090) the completed form to the Port office. To check tidal grid availability, please call (360)779-3505 ext. 1.
