Cruising limitations
Scan constantly for people, objects, and
other watercraft. Be alert for conditions that
limit your visibility or block your vision of
others.
Operate defensively at safe speeds and
keep a safe distance away from people, ob-
jects, and other watercraft.
Do not follow directly behind watercraft or
other boats.
Do not go near others to spray or splash
them with water.
Avoid sharp turns or other maneuvers that
make it hard for others to avoid you or un-
derstand where you are going.
Avoid areas with submerged objects or
shallow water.
Take early action to avoid collisions. Re-
member, watercraft and other boats do not
have brakes.
Do not release the throttle lever when trying
to steer away from objects—you need throt-
tle to steer. Always check throttle and steer-
ing controls before starting the watercraft.
Ride within your limits and avoid aggressive
maneuvers to reduce the risk of loss of con-
trol, ejection, and collision.
This is a high performance boat—not a toy.
Sharp turns or jumping wakes or waves can
increase the risk of back/spinal injury (pa-
ralysis), facial injuries, and broken legs, an-kles, and other bones. Do not jump wakes
or waves.
Do not operate the watercraft in rough wa-
ter, bad weather, or when visibility is poor;
this may lead to an accident causing injury
or death. Be alert to the possibility of ad-
verse weather. Take note of weather fore-
casts and the prevailing weather conditions
before setting out on your watercraft.
As with any water sport, you should not op-
erate your watercraft without someone else
nearby. If you operate further than swim-
ming distance from shore, you should be
accompanied by another boat or watercraft,
but make sure you stay a safe distance
away. It’s good, common sense.
Never operate in water that is less than 60
cm (2 ft) deep from the bottom of the water-
craft, otherwise you increase your chance
of hitting a submerged object, which could
result in injury.
This watercraft is not equipped with lighting
required for night operation. Do not operate
the watercraft after sunset or before dawn,
otherwise you increase the risk of colliding
