The Alder's crew just wrapped up its fall buoy retrieval work, and will be stopping in Grand Haven for rest and recreation, the Coast Guard said.
The vessel is expected to moor at Escanaba Park at 9 a.m. Saturday and remain in port through Monday morning. It will be open for tours from noon to 4 p.m. both Saturday and Sunday.
The Alder is a 225-foot multi-mission buoy-tender. Its homeport is Duluth, Minn. The ship's primary missions are aids to navigation, ice breaking, law enforcement, and search and rescue.
The Alder was one of four U.S. Coast Guard ships that visited Grand Haven for the 2011 Coast Guard Festival.
