The USCG Tamarack (WAGL/WLI-248) was built as a bay and sound tender by the Manitowoc Shipbuilding Company in Manitowoc, Wisconsin, for the U.S. Lighthouse Service in 1934. She transferred to the control of the Navy Department during World War II and in mid-1942 she was converted for use as a submarine rescue vessel and a training ship for submarines. She was transferred to Manitowoc as of 3 December 1942 where she served during the remainder of World War II.   In late June, 1945, the USS Menhaden (SS-377) went out for her sea trials on Lake Michigan, accompanied by the Tamarack. For one exercise, the Tamarack signaled to the Menhaden, more than a mile astern, to do a steep angle surfacing test. After the Menhaden dove to 275 feet, the Tamarack expected her to surface 450 feet away.   Suddenly, 12 minutes later, with a roar, the Menhaden began to surface 70 feet ahead of the Tamarack's bow!   With clanging bells, and orders for full speed astern, the Tamarack managed to stop her forward advance just before she rammed into the Menhaden.   USS Menhaden (SS-377) on sea trials in Lake Michigan, June, 1945.   (Above Photos Taken by Harry Berns, Official Photographer of the Manitowoc Shipbuilding Company, Manitowoc, Wisconsin.
