What drives the evolution of next-generation icebreakers?
A technical review of USCGC Mackinaw demonstrates how specific design and engineering choices translate into operational efficiency.
Nearly 20 years after commissioning, USCG Mackinaw continues to serve as a key reference in icebreaker development. Finnish experts were engaged to perform design checks, ice strengthening checks, and a hull form study.
The article outlines the critical engineering solutions—such as azimuth propulsion and refined hull geometry—that contribute to USCG Mackinaw’s agility and performance in heavy ice conditions across the Great Lakes.
