How did naval officers shape British diplomacy?

How much did the Royal Navy's reliance on diplomacy affect the development of British diplomats?

A great deal; many former naval officers entered the diplomatic service, bringing experience in representation, restraint, and relationship management.

Royal Navy officers spent careers representing the state abroad as well as fighting at sea. That experience trained them in protocol, restraint, local relationships, and the controlled display of force. Many former naval officers subsequently entered the British diplomatic service, carrying those habits into another institution. Naval diplomacy shaped people and administrative culture as well as ship layouts.
