Built specifically for service on the Great Lakes, when Mackinaw was launched, she was the most powerful icebreaker in the world. She went on to a 62 year service career, becoming an icon to the Great Lakes mariners and residents of coastal towns that depended on her to clear a path through the lakes’ thick ice.
When she was decommissioned, she became a museum ship in Mackinaw City, Michigan.
Our Mackinaw plans page offers six ships plans: outboard profile and inboard profile, upper deck plans, lower deck plans, cross section plans, ships lines plans, and shell expansion plan. The Mackinaw would make a beautiful scratch-built ship model, and at a large scale, an impressive radio-controlled ship model of the “Queen of the Great Lakes.
The U.S. Coast Guard cutter White Sumac was originally constructed as a yard lighter (YF416) for the United States Navy in 1943. This class of vessel provided logistical support to naval operations during World War II. Following the War, the Coast Guard acquired eight of these vessels to use as buoy tenders.
Built in 1907, the Steam Tug Hercules was ground-breaking with its steel hull and triple-expansion steam engine. Now the only remaining ocean-going steam tug on the West Coast, Hercules was designated a National Historic Landmark in 1986.
The free ship plans for both of these vessels come from their documentation as part of the Historic American Engineering Record, a program of the National Park Service. The photos and drawings from those surveys are kept by the Library of Congress. The Hercules Photo Gallery is posted, I’ll update when we get the White Sumac Photo Gallery up on the site.
