Before proceeding with our journey, we made a deliberate stop to explore Baddeck Bay, the very waters where Alexander Graham Bell constructed and conducted trials on his groundbreaking hydrofoil boats. We decided to anchor there for the night, allowing us to immerse ourselves in the historical significance of the area.

As morning dawned, we undertook a CTD cast. With this valuable data, we resumed our voyage, continuing our expedition along the scenic Lake Bras d’Or.

Anchoring at a mooring buoy near Kidston Island made it possible to actively use our dinghy for trips to Baddeck and Kidston island. Some photos from our last day in Baddeck.

Alexander Graham Bell – the distinguished polymath, renowned for his multifaceted contributions to science and innovation. He dedicated a substantial portion of his later years to scholarly endeavours at Beinn Bhreagh (, his esteemed estate and research center located in Baddeck.

Our expedition to Baddeck would have been incomplete without a pilgrimage to the Alexander Bell Museum, a hallowed ground in the realm of knowledge. Remarkably constructed and brimming with historical treasures, it stands as a beacon of intellectual curiosity. I wholeheartedly recommend a visit to this institution, where an assortment of artifacts and exhibitions awaits.

For us, practitioners of the marine sciences and sailors, the museum offered a captivating exploration into the realm of marine engineering. Among the intriguing exhibits, hydrofoils took center stage. A hydrofoil, for the uninitiated, assumes the form of a wing affixed to a watercraft. These foils, reminiscent of the wings of an aircraft, are engineered to facilitate the swift flow of water over their surfaces. At higher velocities, this hydrodynamic phenomenon begets lift, causing the vessel to transcend the aquatic medium and effectively levitate, encountering significantly reduced hydrodynamic resistance and enabling enhanced speeds.

Commencing their hydrofoil odyssey in 1911, Bell and his collaborator Casey Baldwin embarked upon a remarkable journey marked by the design, fabrication, and rigorous testing of no less than four hydrofoil prototypes over an eight-year span. Their collective endeavours bore a resemblance to the epic sagas of exploration, albeit on the aqueous stage. Simultaneously, they pursued ancillary endeavours, including the incorporation of hydrofoil technology into sailboats, truly pushing the boundaries of maritime engineering.

Their pinnacle achievement, Hydrodrome #4, colloquially known as HD-4, etched its name in the annals of aquatic velocity. On September 9, 1919, it astoundingly traversed Baddeck Bay at an astonishing 70.86 mph, effectively establishing a world speed record for waterborne craft. This record, akin to a scientific lodestar, remained unbroken for the better part of a decade, underscoring the pioneering spirit and mastery of Bell and his associates. In the domain of aquatic locomotion, HD-4 reigned supreme, shattering hydrodynamic barriers and making profound contributions to the science of hydrofoils.

Unfortunately, by that time the First World War had ended and the demand for high-speed boats capable of catching German submarines had subsided. On 2 August 1922, Alexander Graham Bell died. Cassey Baldwin continued some experiments with hydrofoils at Beinn Bhreagh, but without commercial success, they were probably made before their technological time. This success passed late into the hands of Soviet shipbuilders – my entire childhood in Ukraine was next to flotillas of hydrofoils – Meteor. Voskhod, Raketa, Volga, which were widely used for high-speed transportation along rivers and seas.

But in the world of sailing, there are now a variety of hydrofoils onboard – from foil kitesurfing to IMOCA-60 and American Cup catamarans!
