Aircraft dimensions

For more than 14 years of its development, the SeaBear has proven to have a highly reliable and safe construction in various situations during several thousand flying hours, which makes it the most popular type. At present, there are over 30 aircraft flying.

This new aircraft combines classical flying boat designs with the latest aerodynamic and hydrodynamic technologies. The SeaBear design utilizes a fully cantilevered high aspect ratio wing, and when combined with modern airfoil selection and composite construction results in low drag and low stall speed. The Rotax aircraft engines make the SeaBear operation at any season as easy as a car with high level of autonomy. The SeaBear is made from composite materials to eliminate the corrosion and maintenance problems on water and ensure easy repair and a perfect exterior.

The SeaBear is an aircraft designed by engineers graduated from SSAU (Samara State Aerospace University) with more than 20 years of professional experience. The SeaBear project was based on extensive research done in collaboration with TsAGI (Central Aerohydrodynamic Institute), VIAM (Aviation Materials Institute) and SIbNIA (Siberian Aviation Research Institute), which ensured its outstanding quality. This aircraft is another remarkable achievement of Russian school of engineering.
