Zigzag
The Zigzag pattern steers the
boat from port to starboard and
back, over a specied time and
angle, across your current heading. The
default values are 1.5 minutes and 30°.
Circles
The circle pattern steers the
boat in a constant circle, in a
specied direction and at a
specied time interval. The default value
create a circle that takes 5 minutes to
complete.
The autopilot positions the boat so that
the circle pattern is centered on the point
at which you engage the pattern.
U-Turn
The U-turn pattern turns the
boat around 180° and
maintains the new heading.
Man Overboard
The Man Overboard pattern
turns the boat around with the
intent of running alongside the
point where the Man Overboard pattern
was initiated. The boat must be below
planing speed when using this pattern.
CAUTION: The Man Overboard
pattern is not determined by GPS and
is affected by wind, current, and speed.
Be ready to adjust the throttle and take
the helm to avoid harm to a person in
the water.
