A slushbreaker is an icebreaking vessel that struggles in heavy polar conditions, only capable of navigating through thin, broken, or melting ice. Crews use this term to mock ships that are technically rated for ice but lack the mass, engine power, or structural reinforcement to operate year-round in severe environments.
