Operation
1. General points
- The 360 Docking system is a manoeuvring aid to facilitate coming alongside and
leaving the dock. This system must not in any circumstances be used as a means of
navigation, even during approach manoeuvres in port.
- In some use modes of the system, especially sideways movement, the bow thruster
has to work very hard. This leads to a significant power draw on the bow thruster
battery bank and raises the temperature of the bow thruster motor.
- For its protection, the bow thruster is equipped with a temperature alarm which gives
5 short beeps 10 seconds before cutting off the power to the bow thruster. When the
bow thruster cuts out, keep your hand on the joystick with the bow thruster out of
operation. You need to wait until it has cooled sufficiently before restarting it manually
by pressing both buttons on the bow thruster control simultaneously.
- To avoid this inconvenience and to protect the bow thruster we advise you not to use
the bow thruster for more than 30 seconds at a time and to allow it to cool between
each use.
Note: Once the bow thruster has cut out due to overheating you should allow around
4
hours for it to return to ambient temperature. If it does overheat you can start using
it again without waiting
4
hours but the possible usage time will be reduced.
- After each manoeuvre using the bow thruster, be sure to maintain the charge of the
bow thruster battery bank: either by connecting your boat to the mains socket on the
dock, or by keeping the engine at a cruising speed of at least 1700 rpm (engaged or
disengaged) for at least 30 minutes after the last manoeuvre.
2. Propeller
WARNING
The propeller supplied with the boat is the only propeller validated by the
engine manufacturer that allows optimal operation of the 360 Docking
assembly. No other propeller should be fitted otherwise there will be
serious malfunction of the base or of the engine itself.
