The Shards sail to anchorages around Isla Formentera, part of Spain's Balearic Island group and join the modern "invasion" of Northerners on the beautiful beaches of the island. In a quiet cove they discover an entire village built of driftwood and collect winkles along the seashore. They take the winkles to the crew of a Norwegian sailboat and demonstrate how to cook them along with mussels. Bad weather is coming so they do some underwater tests on their anchors and decide to leave for a safer harbour on the island of Ibiza. In the storm, another boat is washed up onto the beach and Paul and Sheryl assist with the recovery.
