Harold Afloat is a magazine story.
The stormy weather is making Harold extra busy. First he has to rescue two climbers, then he has to rescue another, and then he has to rescue some stranded sheep. When Harold had finished patrol, he saw Peter Sam and told him how tired he was feeling lately. The next day, the sun was shining as Peter Sam passed a busy windsurfing lake. He spotted the patrol boat being winched out of the lake. The skipper explains that the boat had struck some driftwood and they do not have a spare. Later, Peter Sam tells the Thin Controller who telephones the airfield. Harold was soon landing in the lake and bobbing up and down in the water by his floats, looking around for anyone in distress. Harold enjoys being on "floating patrol"!
