Installation recommendations

3.1

Positioning of the thruster tunnel

Several installation examples.
To achieve the optimum performance, po-
sition the thruster tunnel as far forward as
possible.
If, in addition to controlling the movement
of the bow, the stern of the vessel is required
to move sideways, then a second thruster
may be installed at the stern.
For a planing boat the tunnel should, if pos-
sible, be so situated so that when the vessel
is planing it is above the water level thus
causing no resistance.
Installation of two bow thrusters in tandem
(for larger boats). In this case, depending on
weather conditions, one or both bow thrust-
ers may be used.
When choosing the location for the thrust
tunnel, take the following into account for optimum performance:
- The distance A shown in the drawing
must be at least 0.5 x D (where D is the
tunnel diameter).
- The length of the tunnel (distance B)
should be between 2 x D and 4 x D.

We do not advise fitting 2 bow thrusters
into one tunnel; this does not result in
doubling the thrust!
