Interior of wooden Hydrofoil (Hydrodome) HD-4. After this success with the Silver Dart, Bell turned his attention to hydrofoil watercraft. He saw them as a marine analogy to aircraft and Bras d'Or Lake provided a lot of room for experimentation. Bell called the experimental boats "hydrodomes". The HD-4 was his most successful hydrofoil, attaining a speed of 70.8 mph (114 km/h) in 1919. Alexander Graham Bell National Historic Site.
