United States Coast Guard Station Cape Disappointment, situated near Cape Disappointment, Washington, at the mouth of the Columbia River, is the largest United States Coast Guard search and rescue station on the Northwest Coast, with 50 crewmembers assigned. Cape Disappointment Station is also the site of the oldest search and rescue station within the Thirteenth Coast Guard District. The station’s Area of Responsibility reaches from Ocean Park on the Washington Coast south to Tillamook Head on the Oregon Coast.
The station has nine search and rescue boats, including the 52-foot (16 m) motor lifeboat Triumph (52'-SPC-HWX), two 47-foot (14 m) motor lifeboats (47'-MLB), and two 29-foot (8.8 m) Defender class response boats (25'-RBS). The 52'-SPC-HWX and the 47'-MLB have all been designed for operations in heavy surf conditions and are capable of being rolled over by breaking swells and re-right themselves with minimal damage.
Also colocated with the station is the oldest lighthouse on the Northwest Coast of the United States, Cape Disappointment Light, marking the north side of the Columbia River Bar. Less than two miles (3 km) to the northwest is North Head Light, which provides a beacon for the northern approaches to the Columbia River Bar.
The station's primary missions include providing search and rescue to commercial and recreational mariners within 50 nautical miles (93 km) of the Columbia River entrance and providing a maritime law enforcement presence near the approaches to the Columbia River including execution of homeland security missions.
Commonly known as Station Cape "D", station crewmembers respond to 100-200 calls for assistance every year. The station's heaviest workload occurs during the months of early June through mid-September, when an abundance of recreational boaters transit the Columbia River entrance in search of salmon and bottom fish.
