Where would heavy first and second-rate ships of the line not be used?

Heavy first and second-rate ships of the line were typically large, heavily armed vessels designed for fleet engagements in open waters. They played a crucial role in naval warfare during their time, particularly in battles against other ships of the line.

These ships were not ideally suited for use near the coasts or on patrol duty because their size and deep drafts made them less maneuverable in close proximity to shore or in shallow waters. Such operational environments often require smaller, more agile vessels that can navigate safely through shallow conditions and engage effectively in coastal operations.

While heavy ships of the line are capable of long voyages due to their significant cargo and provisions capacity, and can also engage in operations near coasts in specific conditions, their operational effectiveness diminishes in shallower depths and particularly in riverine environments, where smaller, lighter vessels are needed. Therefore, the choice indicating their unsuitability for use near the coasts or on patrol reflects their design limitations in navigating and engaging in such environments.
