|Installation of two bow thrusters behind each other (for larger boats). In this case, depending on weather conditions, one or both bow thrusters may be activated. Should there be doubt whether one larger-bow thruster should be installed, or, alternatively, two smaller units, one behind the other, the latter possibility is definitely worth considering.|
|In the case of a planning vessel: position the tunnel, if possible, in such a manner that it will be clear from the water when the bow rises. In that case there will be no resistance whatsoever.|
|Make sure the the bow thruster is always within reach.|
best results, position the tunnel as far forward in the bow
a stern thruster
If, in addition to controlling the bow, the sideways movement of the stern needs to be controlled, a bow thruster may also be installed in the aft end as a stern thruster.
