On 21st February, 1854, Charles Darwin wrote to his old HMS Beagle midshipman shipmate, Philip Gidley King, who was now living in Australia:
My dear King
I can hardly tell you how pleased I was, about a week ago, to receive your letter dated the 26th. of October. I lead a rather solitary life, & in my walks very often think over old days in the Beagle, & no days rise pleasanter before me, than sitting with you on the Booms, running before the trade wind across the Atlantic.
Reminiscing two decades after the event about sitting with a friend high above the deck of a tall ship with a trade wind in your hair. What better reason could there possibly be for building a new Beagle?
