Construction

Madiz was designed by G. L. Watson, and It is the last surviving ship to have been designed by him personally.^[3][4] She was built by the Ailsa Shipyard in Troon, Scotland on the Clyde.^[4][2]

Madiz is a classic yacht and retains most of her original deck equipment and unique panelling,^[5] the original Burma teak on much of the deck and all the deck’s side panelings.^[6][7] Cuban mahogany in the original master bedrooms and solid oak paneling in the reception areas.^[6][7]

Originally she was powered by two steam engines. These were later replaced by two MTU Mercedes Maybach diesel engines.^[4]

History

The yacht was originally named Triton and her first owner was James Coats.^[4] Following his death, she was purchased in 1913 by Sir George Bullough, owner of the Scottish island of Rùm. He renamed her Rhouma.^[8] During World War I, Rhouma was hired for use as an auxiliary patrol yacht.^[4] Between the wars, she was lengthened and had an upper deck of cabins added, and her engines were converted to run on oil fuel.^[8]

In World War II, she served in the Royal Navy as the Royal Patrol Yacht, HMS Hiniesta, and was used for calibrating huff-duff equipment in GB coastal waters. She later transported King George VI, Queen Elizabeth and Princess Elizabeth on a short victory tour.^[4]

In 1970 she was bought by Greek businessman Costas Keletseki, who renamed her Madiz and had her extensively rebuilt, restoring the original fittings but also modernizing with a conversion from steam to diesel engines.^[9]

In 1989 Madiz was used as the primary setting for an episode of the British TV series Agatha Christie's Poirot.^[10]

Between 2003 and 2006, Madiz underwent another major refit and was re-classed under Lloyd’s Register of Shipping in her original Class of +100A1.^[11][12] After Keletsekis died in 2009, the ship was sold and was available for charter. ^[11] In March 2024 Madiz was placed up for sale again.^[1]
