other water users and hazards such as fixed
objects
Expected system
behaviour

The vessel automatically thrusts to port until it reaches maximum velocity

Then the vessel automatically thrusts to starboard until it reaches maximum
velocity

Approximate test time for a medium-size (twin HJ364) vessel: 2 minutes
30 seconds. Test time is normally longer for larger vessels and may be
shorter for smaller vessels
Test procedure

The vessel master can abort an auto tune test and take manual control
of the vessel at any time, by moving the Mouseboat

Orientate the vessel either head-on or stern-on to any wind or current that is
present
