Best Boat Plan: Uffa Fox's Vision Explained

Uffa Fox was an English boat designer and sailing enthusiast, responsible for many innovations in boat design. He was born on the Isle of Wight in 1898 and began his career as a boatbuilder at the age of 21. Fox is known for his eccentric behaviour and original boat designs, including the introduction of planing hulls and trapezing to dinghy racing. While he designed many significant classes of boats, one of his most famous creations is the Flying Fifteen, a 20-foot keelboat that became a successful post-war design. Fox's connection to Prince Philip, whom he frequently raced with, also contributed to his fame. The Best Boat Plan likely refers to Fox's most successful or iconic designs, such as the Flying Fifteen, which has become an international class with over 4000 boats produced.

Hull design

Uffa Fox was a pioneer in boat design, introducing the technique of planing to dinghy racing. His designs were often radical, and he was unafraid of courting controversy. Fox's hull designs were characterised by their lightweight construction, exploiting developments in moulded plywood, extruded aluminium, and Tufnol.

Fox's most famous design, the Flying Fifteen, was a 20-foot keelboat that became the basis for a range of planing keelboats, from the Flying Ten to the Flying Fifty. The success of the Flying Fifteen inspired Fox to create a "Flying Family" of planing hull designs, including the Flying Thirty and Thirty Five, which could plane in the right conditions.

The hull of the Flying Fifteen was designed to plane in moderate winds while remaining controllable. Fox applied the principles of planing hull design to his keelboats, which were very lightweight compared to other boats of the era. The Huff of Arklow, for example, was a 30-foot keelboat with a waterline length of 30'0".

Fox's designs often featured separate fin keels and rudders, which contributed to the overall lightweight construction of his boats. This design feature can be seen in his keelboats, including the Flying Fox, with a waterline length of 35'0", and the Huff of Arklow.

In addition to his planing keelboats, Fox also designed several dinghies with planing hulls, including the International 14, the Foxcub, and the Super Foxcub. The Avenger, his third dinghy design, was a successful planing dinghy that won 52 first places out of 57 races in 1928.

Propulsion methods

Uffa Fox was a boat designer and sailing enthusiast, responsible for a number of innovations in boat design. He is perhaps best known for his design of the Flying Fifteen, a 20-foot keelboat that became the basis for a range of planing keelboats and cruiser/racer yachts known as the "Flying Family".

When it came to propulsion methods, Fox was a strong advocate for planing hulls, which allowed boats to plane over the water at high speeds. This technique was first introduced to dinghy racing by Fox and played a significant role in the popularity of dinghy sailing. He also contributed to the introduction of trapezing, which allowed sailors to use their body weight to counterbalance the force of the wind on the sails, enabling boats to sail faster and more efficiently.

Fox's designs often exploited wartime developments in materials such as moulded plywood, extruded aluminium, and Tufnol. These materials allowed him to create lightweight boats with separate fin keels and rudders, which were very lightweight compared to other boats of the era.

One of Fox's most successful designs was the Flying Fifteen, which he sketched out while relaxing in a hot bath. This design inspired a range of planing keelboats, including the Flying Ten, Flying Twenty Five, and the Flying Fifty. The Flying Thirty and Thirty Five were even capable of planing in the right conditions.

In addition to his sailing boat designs, Fox also designed several motorboats, including the 25-foot launch Ankle Deep, which was the last boat he designed for his own use.

Materials used

Uffa Fox's designs exploited the latest wartime developments in materials such as moulded plywood, extruded aluminium, and Tufnol.

Fox's first skerry cruiser, Vigilant, was based on the archipelago cruiser rule. It was a 22-square-metre cruiser with an extremely light displacement. Fox's design for the International Sailing Canoe was a boat with a V-shaped bow and a relatively wide and flat underwater area at the rear. This design differed significantly from the round canoe shape commonly used in America.

Fox's most famous design, the Flying Fifteen, was a 20-foot keelboat with the rig of an international 14-foot dinghy. This design was so successful that Fox developed a range of planing keelboats, from the Flying Ten to the Flying Twenty-Five. He then used similar hulls to produce a range of cruiser/racer yachts, from the Flying Twenty-Five to the Flying Fifty. The Flying Thirty and Thirty-Five designs were even capable of planing in the right conditions.

Fox also designed several keelboats loosely based on the Flying Fifteen concept, with separate fin keels and rudders. These boats were very lightweight compared to other boats of the era. For example, the Huff of Arklow for Douglas Heard was 30 feet long on the waterline, while the Flying Fox for Fred Brownlee was 35 feet long.

In addition to his sailing boat designs, Fox also designed rowing boats. The Britannia, used by John Fairfax for the first solo-rowing expedition across the Atlantic Ocean in 1969, was described as "the Rolls-Royce of rowing boats, made of mahogany." It was self-righting, self-bailing, and partly covered. Fox also designed the Britannia II, used by Fairfax and Sylvia Cook to row across the Pacific Ocean in 1971-1972.

Boat construction techniques

Uffa Fox was a self-taught boat designer and sailing enthusiast who introduced several innovations in boat design. His most famous design, the Flying Fifteen, was inspired by the shape of a high-speed power craft, the Maple Leaf IV, which he had worked on during his apprenticeship at SE Saunders. Fox's designs were known for their lightweight construction, with moulded plywood, extruded aluminium, and Tufnol exploited during the war.

Fox's construction techniques were influenced by his experience in boatbuilding and shipbuilding. He founded his own shipyard at the age of 21, setting it up in a decommissioned ferry. Fox's early boats, such as the Avenger, were built using wooden boat-building techniques, with the Avenger being constructed from mahogany veneer. Fox's designs were also known for their lightweight construction, with the Huff of Arklow and Flying Fox being notably lighter than other boats of the era.

Fox's design philosophy centred around the idea that a dinghy hull, when shaped correctly, could be made to plane over the water. This idea of planing hulls was first introduced in his design for the International Fourteen Footer Avenger, which dominated the racing scene in 1928. Fox then applied this concept to other classes, including the Flying Fifteen, which became the basis for a range of planing keelboats and cruiser/racer yachts.

In addition to his work on dinghies, Fox also designed several keelboats based on the Flying Fifteen concept, with separate fin keels and rudders. These keelboats were also very lightweight compared to other boats of that era. Fox's design for the Britannia rowboat, used by John Fairfax for the first solo-rowing expedition across the Atlantic, showcased his ability to create self-righting and self-bailing constructions.

Fox's construction techniques and design philosophy were influenced by his practical experience and experimentation. He believed strongly in trial and error, and his designs often reflected his intuitive understanding of what made a boat fast, seaworthy, fun to sail, and safe. Fox's force of personality and self-belief also played a significant role in his success, as he fearlessly pursued radical avenues to improve boat performance.

Uffa Fox's sailing performance is a testament to his innovative boat designs and sailing prowess. Fox, an English boat designer and sailing enthusiast, made significant contributions to the world of sailing, particularly in the development of dinghy sailing.

One of his notable achievements was the introduction of planing hulls to dinghy racing. Fox's designs, such as the International 14 and the Flying Fifteen, showcased his understanding of hydrodynamics and his ability to create fast and seaworthy vessels. The Flying Fifteen, in particular, became a popular design with fleets in every state and territory of Australia by the 1970s, solidifying Fox's reputation as a leading designer.

Fox's sailing performance extended beyond design innovations. In 1928, sailing his International Fourteen, Avenger, Fox achieved an impressive racing record, winning 52 out of 57 races, including the prestigious Prince of Wales Cup. Fox's sailing capabilities were not limited to racing, as he also embarked on adventurous voyages. In one instance, he sailed Avenger across the English Channel to Le Havre and back, covering 100 nautical miles and enduring heavy seas, demonstrating his boats' performance and endurance.

Fox's sailing performance and reputation extended beyond the racing circuit. He became a close friend of Prince Philip, Duke of Edinburgh, in 1949, and they frequently raced together at Cowes Week. Fox's association with royalty brought him further into the public eye, and he became a well-known figure in sailing circles and beyond.

In addition to his sailing accomplishments, Fox also contributed to the design of airborne lifeboats during World War II. These lifeboats were carried by aircraft and deployed via parachute to rescue downed aircrews. Fox's innovative design saved the lives of countless airmen, and he considered it his most fulfilling creation.

While Fox's business acumen may not have matched his inventive genius, his impact on sailing performance and boat design is undeniable. His designs, including keelboats and dinghies, exploited wartime developments in materials such as moulded plywood and extruded aluminium, making his boats lightweight and high-performing.

Uffa Fox's sailing performance, both on and off the racing circuit, solidified his legacy as a designer and sailing enthusiast whose contributions to the sport continue to resonate today.
