Fixing a leak

En route to Holland, we (and other vans!) had spent the night at the ferry terminal in Harwich, ready to catch the ferry early next morning. During the night, there was a heavy rain storm. When I got up, I discovered some water had leaked into the van, presumably from the vent in the roof. This picture shows our son Roger, assisted by his daddy, applying sealant (borrowed from a kind neighbour) around the rim of the vent, when we reached their home in Denmark.
