A paddle board drifted toward the marina with its sleeper under a hat

You fell asleep on a paddle board off Medano Beach on Saturday morning with your hat over your face and drifted slowly toward the marina, past the yachts, like a very relaxed spy. I stood on the sand holding a coffee and a growing sense of horror. You woke up three boats in, saluted a yacht owner who had come out on deck, and paddled back with great dignity. I would like to know what you were dreaming about. I would also like to know whether the yacht owner waved.
