Figure 18: Moving Sideways, Triple Jets
With triple jets
Using all three jets to move sideways gives best results.
The following procedure moves the vessel to port. To move to starboard just transpose port and starboard.
1
Set steering to ahead, all three reverse ducts to the zero speed position and RPM on all engines to the same value.
2
Use the centre jet reverse duct to control fore and aft movement (duct approximately 80% reversed).
3
Move the port reverse control lever to full astern and the starboard lever to full ahead. This will cause the bow of
the vessel to swing to port.
4
As the bow begins to swing, turn the helm to starboard to counteract the port rotation of the vessel. The vessel will
now move sideways to port.
5
This method of sideways manoeuvring should result in 33% more side thrust than if only two jets were used. Once
set up, only the centre jet reverse control lever and the helm need to be used for controlling the sideways
movement.
If the vessel is moving sideways too fast:

Set the reverse control levers to zero speed.

Return the helm to the centre position.
Alternatively set the controls for sideways movement in the opposite direction until the vessel
stops moving.
The required control settings will vary according to wind and tide conditions.
