Carl E. Moses Boat Harbor (CEM)

Unalaska, AK

Carl E. Moses Boat Harbor (CEM) is located in Unalaska, Alaska, on the island of Amaknak in the Aleutian Islands chain, which forms part of the North Pacific Coast and is characterized by rugged, volcanic terrain and exposure to harsh maritime weather. Situated in a protected bay along the shores of this remote archipelago, the marina primarily serves commercial fishing vessels and supports the local boating community in one of Alaska's key fishing ports. It operates in an area influenced by the Pacific Ocean's dynamic currents and the nearby Bering Sea, making it essential for regional maritime activities.

Marina Parking & Access Control

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.
