Collections Lady Guilford Lady Guilford In 1819 Scottish boatbuilder Lachlan McLean was commissioned by the Marquess of Bute to build a sailing galley. Using local oak and larch, McLean built this beautiful three-masted open sailing boat. The Marquess named her Lady Guilford, probably in honour of his new wife, Lady Maria North, daughter of the Earl of Guilford. The boat was later re-rigged as a schooner and became a working boat. Later, an engine was added and she was in service until the 1930s Lady Guilford is a very early, complete and unaltered survivor of a Scottish vessel of any type, possibly the oldest surviving Scottish built boat. She is loan to the Scottish Maritime Museum from the present Marquess of Bute, Mount Stuart, Isle of Bute.
