[1] In 1901 Morgan-Giles moved to London and started a business in Hammersmith designing small wooden boats for cruising and racing.

In 1908–09 Morgan-Giles's future wife, Ivy Carus-Wilson, ordered a 14 feet (4.3 m) racing dinghy named Myosotis from the company, in which she competed with great success.

[5] His eldest son, Morgan Morgan-Giles, joined the navy in 1932 at the age of 18, served with distinction in World War II (1939–45), and later rose to the rank of rear-admiral.

[6] With the outbreak of World War II the boatyard was expanded and selected by the Admiralty for repair and construction of naval vessels.

After the return of peace the yard resumed construction of pleasure boats, including motor launches and canal cruisers.

[1] The six sailing boats built for naval training were the Pegasus, Wyvern, Gryphis, Martlet, Leopard and Galahad.

Several of his wooden or galvanised steel yachts are still in use today, such as the 8 metres (26 ft) Hispania VI, built for King Alfonso XIII of Spain.
