The Triumph Submersible

The Triumph 3 person submersibles are based on SEAmagine’s patented flexible surface ballast system that provides these vessels a high freeboard and low draft when on the waters surface. At surface and underwater, the Triumph is highly stable sub that does not pitch or roll and offers smooth maneuver controls. The submarine has considerable spare buoyancy ballast that permits high payload recovery. Additionally, the sub can readily hover at a specific location and

accurately maintain its position, ideal for a for observations and underwater filming. These submarines feature an acrylic cabin with a clam shell design that fully opens in half offering a 1.53m hatch for comfortable boarding and exit. The cabin sits two passengers in the front of the sphere with the pilot seated in the center rear section. This cabin design offers the passengers a panoramic underwater view both overhead and directly below. The pilot and

passengers’ great field of views are not obstructed by any overhead entry hatch proving a great underwater experience. These submarines have strong propulsion power and solid controls that allow the pilot to safely drive up close to reefs and seamounts and observe sea-life in incredible details. These subs can be equipped with a wide range of subsea equipment such as cameras, robotic arms and more.
