Flexible Applications

We offer full customization of shaft arrangements. The following illustrations show some of the most usual configurations.

 

H-gear configuration:

This configuration is recommended wherever the space in the vessel, or the vessel's trim, allows it. The arrangement is simple and light. It also has normal reduction of noise and vibrations.

U-gear configuration:

This is the best solution if space considerations or the vessel's trim require the engine to be located as far as possible towards the stern.

PTI-gear configuration:

This is the most flexible configuration. The propeller can be run optimally on one or two engines, depending on the desired speed. This arrangement provides extra good operational reliability. Because of the position of the engines, this configuration fits well into the hull of a catamaran.
