In Biggles at World's End, the Seaspray was a boat which belonged to Mr Scott, a ship's chandler at Punta Arenas. A ten-ton ketch with a Petter engine, white hull and red sails, the boat was rented out to two British botanists, Carter and Barlow who used it to sail among the islands in the Magellan Straits searching for botanical specimens. The Seaspray was wrecked when Carter and Barlow got caught in a blizzard. Biggles later found a piece of red fabric in an Indian canoe which turned out to be a piece of sail from the boat. After the rescue of Barlow and Carter, Biggles found the wreckage lying in three fathoms of water.
