What is the maximum thickness of ice on the 45 superstructure?

The maximum thickness of ice allowed on the 45-foot superstructure is 3/4 inch. This limit is established to ensure the structural integrity and operational performance of the vessel. Exceeding this thickness can lead to issues such as added weight, compromised stability, and potential damage to the superstructure or other critical components.

Operating with a regulated ice thickness is essential for maintaining the vessel’s capabilities, as excessive ice can affect maneuverability and control, posing safety hazards during navigation. Understanding these specifications is crucial for any coxswain to ensure safe and efficient operations in icy conditions.

The other suggested thickness options do not align with the established guidelines for the 45-foot superstructure, either being too thin to provide adequate protection against ice or too thick, which could compromise safety and operational effectiveness.
