To engage Skyhook the drives must be shifted into neutral. However, after engaging Skyhook the drive response is not the same
as with drives normally shifted into neutral. The propellers will turn when Skyhook is activated, and propeller rotation may not be
obvious. As in all boats when the engines are running, it is important to ensure that no one is in the water near the boat and to
ensure that passengers are secure. Compliance with this practice is even more important when Skyhook is engaged.
Before engaging (activating) Skyhook the operator must:
•
Inform passengers how Skyhook operates, to stay out of the water and off the swim platform, and to be alert for any sudden
shifts in the boats position.
•
Check to see no one is on the swim platform, or in the water anywhere near the boat.
When Skyhook is engaged the operator must:
•
Remain at the helm and maintain a vigilant watch.
•
Disengage (deactivate) Skyhook if anyone enters the water or approaches the boat from the water.
The capability of most vessels limits the ability of Skyhook to counteract currents of up to 2 knots (2.3 MPH) when the boat is
sideways to the current. If you notice your boat drifting sideways while Skyhook is engaged, move the bow or stern more directly
into the current to help reduce the effects of the current.

WARNING
When the Skyhook is engaged, the boat stays in a preset position; however, Skyhook can disengage unexpectedly. When
Skyhook disengages, the boat does not hold the preset position and may drift, causing the potential of damage or personal
injury. The helm operator must be able to take control of the boat when using Skyhook.
Skyhook relies on an operational GPS receiver and operational heading sensor. Occasionally, due to imperfect satellite
communications, the GPS signal may be temporarily unavailable. Skyhook will continue to operate through a GPS signal outage
for up to 10 seconds, but disengages if the GPS signal outage persists. If Skyhook disengages, you are alerted by the sound of
a horn and the indicator light on the Axius Premier Trackpad for the "SKYHOOK" button turns off. In such a circumstance, the
boat will drift with the wind or current because the engines continue to run but the drive units are now in neutral.
Skyhook performance is largely dictated by the performance of the onboard Zeus GPS system. The Zeus GPS system is accurate
within 3 meters (10 feet) when receiving a Wide Area Augmentation System (WAAS) correction. WAAS is a system of satellites
and ground stations that provide GPS signal corrections. When WAAS is not available, the performance of the system maintains
the boat within 20 meters (60 feet) of the desired position.
Engaging (Activating) Skyhook
IMPORTANT: Activities in the water near the vessel while Skyhook is engaged may result in injury. The Captain (or operator) and
passengers should read and observe the warning labels on the boat before Skyhook is engaged.
