The system outputs lift, drag (Fbx) and side (Fby) forces as well as pitch and roll moments (yaw is missing presently) that need to be added into the corresponding channels of the craft specific hydrodynamics configuration. A visualization of the configuration is shown in the image below. | The system outputs lift, drag (Fbx) and side (Fby) forces as well as pitch and roll moments (yaw is missing presently) that need to be added into the corresponding channels of the craft specific hydrodynamics configuration.

The marker is placed at hydro RP, the hydrodynamic reference point. Note that the system only supports flat planing surfaces but at planing speeds only the rearmost part of each surface will be in contact with water, anyway.]] | ||
The integration of the planing drag into the craft specific hydrodynamics configuration is shown below. First the drag from the various surfaces is combined. | The integration of the planing drag into the craft specific hydrodynamics configuration is shown below.
