Ocean Cloud is the closing track on the first disc on Marillion's 2004 double album, Marbles. It is dedicated to the late Don Allum, an ocean rower who rowed the Atlantic Ocean both ways. The album's liner notes contain a URL to the online log of Allum's last voyage.
The Hogarth-penned lyrics deal mostly with Allum and his lone oceanic voyage. Indeed, the song's working title had been "Pacific Rower". However, the lyrics also…
He's seen too much of life
And there's no going back
The loneliness calls him
And the edge which must be sharpened
