SHIP AHOY! The Wiljan was built in Holland in 1910 as a 62-ton sailing boat carrying cargo such as sugar beet, flax and reed and was then called De Tijd Zal 't Leren ("Time Will Teach Us"). She was brought to the river Thames in 1972 by an Englishman who converted and restored the vessel, lining the interior of the saloon and two of the cabins with maple wood from the dance floor of the Lensbury Club in Teddington, most of which had been destroyed by a fire. She's now moored in front of St Mary's Church, close to Battersea Square in London, and has a wheel house, stern store room, engine room, three cabins, heads, saloon and galley, and comes with parking. Foxtons (0171-801 1111) invites offers in the region of pounds 145,000.
