1. A drive installation for surface skimmers and hydrofoils, with at least one propulsion unit including a first internal combustion engine as main engine operable to drive a main propeller for normal surface skimming or foil-borne operation and a second internal combustion engine as auxiliary engine driving an auxiliary propeller for displacement operation, characterized in that at normal surface-skimming or foil-borne operation at all main propeller speeds corresponding to the actual cruising speed of the boat, the auxiliary engine drives the main propeller, in addition to the drive of the main propeller by the main engine, by way of a multiple input gear means arranged between the main engine and the main propeller and by way of a variable speed transmission means.
2. A drive installation according to claim 1, characterized in that the variable speed transmission means is a hydrodynamic torque converter arranged between the auxiliary engine and the multiple input gear means.
3. A drive installation according to claim 1, characterized in that saiD main engine is a gas turbine.
4. A drive installation according to claim 3, characterized in that said auxiliary engine is a Diesel engine.
5. A drive installation according to claim 4, characterized in that the variable speed transmission means is a hydrodynamic torque converter arranged between the auxiliary engine and the multiple input gear means.
6. A drive installation according to claim 1, characterized in that a hydrodynamic torque converter of the converter-coupling type is used as variable speed transmission means, and in that the power train between auxiliary engine and main propeller includes additional mechanical gear means so that at nominal speed of the auxiliary engine and at the propeller speed corresponding to the most frequently used cruising speed of the boat, the torque converter operates in its coupling range.
7. A drive installation according to claim 6, characterized in that the additional mechanical gear means is a speedup transmission means between the auxiliary engine and an input shaft of the torque converter.
8. A drive installation according to claim 6, characterized in that the additional mechanical gear means is arranged in the multiple input gear means between an output shaft of the torque converter and a propeller shaft for the main propeller.
9. A drive installation according to claim 6, characterized in that the multiple input gear means is combined with a reduction gear which is normally required with gas turbines.
10. A drive installation according to claim 9, characterized in that the auxiliary engine is arranged to the rear of the main engine and in that power takeoff is available at both ends of the auxiliary engine, namely at the front-end to drive the torque converter and at the other end to drive the auxiliary propeller.
11. A drive installation according to claim 10, characterized in that the auxiliary propeller can be uncoupled from the auxiliary engine by disengageable means.
12. A drive installation according to claim 11, characterized in that the additional mechanical gear means is a speedup transmission means between the auxiliary engine and an input shaft of the torque converter.
13. A drive installation according to claim 11, characterized in that the additional mechanical gear means is arranged in the multiple input gear means between an output shaft of the torque converter and a propeller shaft for the main propeller.
14. A drive installation according to claim 11, characterized in that said main engine is a gas turbine.
15. A drive installation according to claim 14, characterized in that said auxiliary engine is a Diesel engine.
16. A drive installation according to claim 1, characterized in that the multiple input gear means is combined with a reduction gear which is normally required with gas turbines.
17. A drive installation according to claim 2, characterized in that the auxiliary engine is arranged to the rear of the main engine and in that power takeoff is available at both ends of the auxiliary engine, namely at the front-end to drive the torque converter and at the other end to drive the auxiliary propeller.
18. A drive installation according to claim 17, characterized in that the auxiliary propeller can be uncoupled from the auxiliary engine by disengageable means.
