The attractiveness of the DDL-1 ground-effect vehicle for business

Thanks to its high lift-to-drag ratio, the DDL-1 wing-in-ground-effect amphibious craft consumes less fuel than seaplanes, helicopters, and gliding boats, both in terms of unit mass of payload and unit length of travel, while maintaining a high cruising speed. It uses automotive gasoline as fuel, which is cheap and widely available.

The hybrid composite construction of the hull is not susceptible to corrosion. The use of automotive power systems reduces maintenance costs compared to turboprop engines.

The DDL-1 is stable in flight due to its unique aerodynamics. It is also stable in displacement mode thanks to the construction of the boat-like fuselage and two floats. Furthermore, the DDL-1 wing-in-ground-effect amphibious craft is capable of safely landing even in the event of engine failure.

To moor the DDL-1 and facilitate loading/unloading of cargo, boarding/deboarding of passengers, only one dock is required, which can be constructed using plastic pontoons, for example.

For passengers, the DDL-1 provides a comfortable journey without shaking, rocking, or turbulence.

The certification of the DDL-1 is carried out by organizations certifying marine vessels in the operating country, as it is considered a marine vessel according to international maritime regulations. The DDL-1 is not subject to aviation regulations (FAA, EASA, and others).

Due to the fact that the DDL-1 is a wing-in-ground-effect amphibious craft rather than an airplane, it can be operated not only by pilots but also by boat captains. Only a short training course will be required.
