A U.S. Coast Guard Jayhawk helicopter crew hoisted a mariner from a grounded vessel near Clatsop Spit Saturday.

Early Saturday morning, the Coast Guard received a report from the mariner saying his vessel had lost its anchor and grounded near Buoy 12 on Clatsop Spit.

A 29-foot response boat crew from Station Cape Disappointment went to the scene but was unable to locate the vessel because of heavy fog. The Coast Guard utilized a cellphone ping, sounding horns and good Samaritans to locate the mariner, who was suffering from hypothermia.

The Coast Guard helicopter hoisted and transferred the man to medical personnel at Air Station Astoria. The mariner was reported in stable condition.
