Scope and Applicability.
This instruction applies to U.S. Navy ship designs, and commissioned ships over 150 feet in length or manned by 100 or more persons. Smaller ships will be treated on a case-by-case basis, with established criteria providing a foundation for habitability design, recognizing that design constraints may preclude reasonable attainment of all larger ship standards.
