HUMPHREE FUNCTIONS OVERVIEW
AUTOMATIC TRIM
Automatic Trim Control (AUTO TRIM) adds automatic adjustment of the
vessel trim to provide optimum running trim for the highest speed and lowest
fuel consumption. The trim and list can be manually adjusted by deploying or
retracting the interceptors and/or the ns.
AUTOMATIC LIST
When running in a straight course, Automatic List Control (AUTO LIST)
corrects the boat list to a set list angle, usually zero degrees. When the vessel
enters a turn, the system allows the vessel to heel naturally during the turn and
then continue to correct the vessel to the set list angle.
COORDINATED TURN
Coordinated Turn automatically adjusts the heeling angle of the vessel during turns to reduce the side forces for
everyone on board. The system continuously monitors the rudder position during the turn and the interceptor
blade movement is coordinated with the rudder movement. With a controlled heel angle, higher turning speeds
and better comfort can be achieved.
STABILIZATION
Boats are constantly exposed to waves that cause roll and pitch motions
resulting in reduced comfort on board. With Stabilization, the interceptors and/or
stabilizing ns are instantly actuated to provide lift which counteracts the vessel
motions and at the same time optimizes the running trim and list angle.
ZERO SPEED STABILIZATION
Zero Speed Stabilization reduces roll motion when the vessel is not moving. The
function can be used when the boat is at anchor or unanchored. Zero Speed can
be activated when the vessel speed is below 4 knots.
FISH HUNTING MODE
Fish Hunting Mode suits sport shing boats and makes the vessel easy to steer
with a sh on the hook. When the Fish Hunting Mode is activated, the ns
gradually deactivate and rotate freely.
VESSEL MOTION MONITORING
Vessel Motion Monitoring (VMM) is used to monitor impacts and motion
sickness when the vessel is moving. The sensors in the RCU measures
3D-accelerations and presents live data on the display. On the VMM screen,
there is a yellow and a red warning level for the acceleration impacts.
INTERCEPTOR STEERING
Interceptor steering enhances the water jet steering by deploying the
interceptors and keeping the water jet thrust undeected for small steering
commands. For larger steering commands, a combination of interceptors and
water jet deection results in an increased steering force and reduced turning
radius. The steering interceptor position bar is seen in the main screen when
installed.
