The case for a naval sail training ship

What is the argument for a navy operating a large sail training ship?

Leadership training is the stated rationale, but the need for a sailboat is disputed; prestige and environmental presentation are also suggested motives.

Leadership training is the main justification offered for a large naval sailing ship. The objection is that this does not explain why leadership has to be taught aboard a sailboat. Appearance and the example of other navies are suggested as further attractions. Claims about renewable propulsion and efficiency also feature in this skeptical assessment of the proposal.
