About Thomsen Harbor

Off the north end of Katlian Street, south of Eliason Harbor. The Harbor Department: Office hours are 8am to 4pm Monday through Friday. We are located adjacent to Thomsen Harbor at 617 Katlian St. Fax # is (907) 747-6278. The City and Borough of Sitka Harbor Department operates and maintains 5 boat harbors to include Crescent Harbor, Sealing Cove Harbor, ANB Harbor, Thomsen Harbor and Eliason Harbor. The city has a tidal grid available, a gear work float and a drive down load/unload zone. Sitka also has a moorage area at the Port Facility (City Wall) that can handle up to a 300’ vessel, there is also a hoist with a maximum limit of 1,500 lbs. Sitka moors a large fleet of commercial fishing vessels, recreation and charter vessels. During the summer we also see large yachts, from all over the world, visit our harbors. All the Sitka harbors are within walking distance to grocery stores, marine supply stores, restaurants and downtown. The harbor department also have restrooms at all harbors as well as shower facilities on site above Eliason Harbor. In 2016, Sitka became the 4th Alaska Clean Harbor. To become a certified Alaska Clean Harbor, a facility must implement best management practices that help to prevent pollution and reduce waste at their facility. They must be pro-active in communicating with their customers and dedicated to providing services and assistance to their staff and boaters to protect water quality. We know that drips and spills will still happen, but through working with Alaska Clean Harbors, we believe that harbors, like Sitka, are making change and improving our water quality and the quality of our harbors.
