Sir Francis Charles Chichester KBE (17 September 1901 – 26 August 1972), aviator and sailor, was knighted by Queen Elizabeth II for becoming the first person to sail single-handed around the world by the clipper route, and the fastest circumnavigator, in nine months and one day overall.
Chichester was born in Barnstaple, Devon, England, and was the son of a clergyman of the Church of England, Charles Chichester, himself the seventh son of Sir Arthur Chichester, 8th Baronet. His mother was Emily Annie, daughter of Samuel Page. At the age of six he was sent as a boarder to a prep school, then attended Marlborough College during the First World War. At the age of eighteen, Chichester emigrated to New Zealand, where in ten years he built up a prosperous business in forestry, mining and property development, only to suffer severe losses in the Great Depression.
After returning to England in 1929 to visit his family, Chichester took flying lessons at Brooklands, Surrey, and qualified as a pilot. He then took delivery of a de Havilland Gipsy Moth aircraft, which he intended to fly to New Zealand, hoping to break Bert Hinkler's record solo flight back to Australia on the way. While mechanical problems meant that the record eluded him, he completed the trip in 41 days. The aircraft was then shipped to New Zealand. Finding that he was unable to carry enough fuel to cross the Tasman Sea directly, Chichester had his Gipsy Moth fitted with floats borrowed from the New Zealand Permanent Air Force, and went on to make the first solo flight across the Tasman Sea from East to West (New Zealand to Australia). He was the first to land an aircraft at Norfolk Island and Lord Howe Island. Again, the trip was delayed: after his aircraft was severely damaged at Lord Howe, he had to rebuild it himself with the help of islanders.
Though the concept of "off-course navigation" (steering to one side so you know which way the error is) is probably as old as navigation, Chichester was the first to use it in a methodical manner in an aircraft. His only method of fixing his position was to take sun sights with a sextant. As a solo pilot, this was a difficult thing to do in a moving aircraft, as the pilot also needed to fly the aircraft at the same time. After the sun sight was taken, he then had to make calculations by long-hand. As all this could be unreliable, Chichester needed an alternative. When he reached a point at which the sun was at a pre-calculated altitude above the horizon, the pilot then made a 90-degree turn to the left (or right as pre-calculated) and then flew along this line until the destination was reached. Since he did not know in advance when he would arrive at a line of position passing through his destination, he pre-calculated a table or graph of the Sun's altitude and azimuth at his destination for a range of times bracketing his ETA. The advantage of this method was that the effects of drift were reduced to errors in distance travelled, usually much smaller. Since Chichester arrived at Lord Howe Island in the afternoon, the Sun was to his northwest when he made his turn. Some hours before making his turn, close to local noon when the Sun was to his north, Chichester made two observations with his sextant to check his dead-reckoning course.
The general principle was, when the Sun is to the right or left of one's course one can check one's course but not one's distance to the destination. When the Sun is ahead or behind one's course one can check the distance to one's destination but not one's course. So he planned his final approach to follow a line of position directly to his destination. This technique allowed him to find tiny islands in the Pacific. He was awarded the inaugural Guild of Air Pilots and Air Navigators Johnston Memorial Trophy for this trip. Chichester then decided to circumnavigate the world solo; he made it to Japan but at Katsuura, Chiba he collided with an overhead cable, sustaining serious injuries.
Second World War cartography
Unable to join the Royal Air Force at the outbreak of the Second World War due to age and eyesight, he was not granted a commission until 14 March 1941 when he joined the Royal Air Force Volunteer Reserve for the duration of hostilities. His civil occupation was listed as Air Navigation Specialist. His first posting was to the Air Ministry in the Navigation section of the Directorate of Air Member Training, where he served until August 1942. In July 1943 he was sent to the Empire Central Flying School where he instructed in navigation until released in September 1945. He wrote the navigation manual that allowed the pilots of single-handed fighter aircraft to navigate across Europe and back using kneeboard navigation similar to that which he had used in the Pacific.
At the end of the war, he stayed in the United Kingdom. He purchased 15,000 surplus Air Ministry maps, initially pasting them onto boards and making jigsaw puzzles out of them, and later founded his own successful map-making company.
In 1958, Chichester was diagnosed with terminal lung cancer. (This may have been a mis-diagnosis; Dr. David Lewis, a London physician who competed against Chichester in the first solo trans-Atlantic race, reviewed his case and called Chichester's abnormality a "lung abscess".) His wife Sheila put him on a strict vegetarian diet (now considered to be a macrobiotic diet) and his cancer went into remission. Chichester then turned to long-distance yachting.
In 1960, he entered and won the first single-handed transatlantic yacht race, which had been founded by 'Blondie' Hasler, in the yacht Gipsy Moth III. He came second in the second race four years later.
On 27 August 1966 Chichester sailed his yawl Gipsy Moth IV from Plymouth in the United Kingdom and returned there after 226 days of sailing on 28 May 1967, having circumnavigated the globe, with one stop (in Sydney). By doing so, he became the first person to achieve a true circumnavigation of the world solo from West to East via the great Capes. The voyage was also a race against the clock, as Chichester wanted to better the typical times achieved by the fastest fully crewed clipper ships during the heyday of commercial sail in the 19th century (the first recorded solo circumnavigation of the globe was achieved by Joshua Slocum in 1898 but it took him three years with numerous stops – Slocum also took up the harder challenge of sailing east to west, against the prevailing wind).
Honours and later life
In July 1967, a few weeks after his solo circumnavigation, Chichester was knighted, being appointed a Knight Commander of the Order of the British Empire for "individual achievement and sustained endeavour in the navigation and seamanship of small craft". For the ceremony, the Queen used the sword used by her predecessor Queen Elizabeth I to knight the adventurer Sir Francis Drake, the first Englishman with his crew to complete a circumnavigation. Gipsy Moth IV was preserved alongside the Cutty Sark at Greenwich.
Chichester was also honoured in 1967 by a newly issued 1/9d (one shilling and nine pence) postage stamp, which showed him aboard Gipsy Moth IV. This went against an unwritten tradition of the General Post Office, because Chichester was neither a member of the royal family nor dead when the stamp was issued.
In 1968, when Donald Crowhurst was trying to win the Sunday Times Golden Globe Race, a single-handed round-the-world event, it was Chichester who dismissed Crowhurst's wildly exaggerated reports of his own progress, which had fooled many enthusiastic supporters.
In 1970, Chichester attempted to sail 4,000 miles in twenty days, in Gipsy Moth V, but failed by one day.
Sir Francis Chichester had two sons, George and Giles. His younger son, Giles Chichester, is a British politician, and Conservative Member of the European Parliament for South West England and Gibraltar.
Gipsy Moth IV's restoration
By the early 2000s, the condition of Gipsy Moth IV, even though it continued to rest in a Greenwich dry dock hoist, had seriously deteriorated. Admirers of the vessel knew that she required a complete restoration if her life was to be extended. A campaign was launched in 2003 by Paul Gelder, editor of Yachting Monthly magazine, to sail the yacht around the world a second time in observance of the 40th anniversary of Chichester's epic voyage (and coincidentally the 100th birthday of the magazine).
In November 2004 she was lifted out of Greenwich dry dock (which some had called the yacht's "grave") after being sold to the UK Sailing Academy in Cowes, Isle of Wight, for a token £1 and a gin and tonic, said to be Chichester's favourite tipple. The UKSA, Yachting Monthly and the Maritime Trust were the three major project partners in the bold campaign to save the yacht. She was taken by road back to Camper & Nicholson, her original builders in Gosport.
On 20 June 2005 Gipsy Moth IV was relaunched after a £400,000 refit with money raised by donations from the public, and equipment and services given by the British marine industry. In September 2005 she embarked on a 21-month educational round-the-world voyage with the Blue Water Round the World Rally, via the trade wind route and the Panama and Suez Canals (not the Capes as had been followed in its first circumnavigation). In spring 2006, she ran aground on an atoll in the South Pacific. An extensive restoration in Auckland was required to repair the yacht, which was successfully refloated in June 2006. After being accompanied into Plymouth by a flotilla of boats, the Gipsy Moth IV docked at West Hoe Pier on 28 May 2007, as she had done exactly 40 years earlier, to complete her journey round the world.
The yacht's restoration and the second circumnavigation are described in Paul Gelder's 2007 book, Gipsy Moth IV: A Legend Sails Again.
Other posthumous honours
Norfolk Island issued a stamp, in 1981, commemorating the first landing of an aircraft on the Island, Chichester's Gipsy Moth Mme Elijah, at Cascade Bay on 28 March 1931. Another stamp (14 cents) was issued by Norfolk Island at a later date showing Chichester's seaplane.
A memorial plaque to Chichester was unveiled at the family home at 9 St James's Place, SW1 in September 1993.
