Exercise 7: Planing speed operation
Objective:
This exercise teaches you how the watercraft feels and operates at higher speeds. It
also illustrates what happens when the watercraft slides or partially spins due to abrupt
high speed turning.
Skills:
Throttle control, turning, shifting weight, and sliding.
Directions:
Because of the high speeds involved, do this exercise in a very large area, in open, calm
water free of traffic or other obstacles. Remember, you need throttle to steer.
Drill 1: Turning at planing speed
1. Accelerate to planing speed, and then make a turn.
2. Practice making ovals using right and left turns.
3. Repeat the drill, starting with gradual turns and slower speeds, and then working up as your skill and confidence build.
You will notice how the watercraft no longer “carves” its turns as it did at sub-planing
speed.
The watercraft can only make so sharp a turn at any given planing speed.
When the handlebars are turned more than is necessary, the watercraft may start sliding
and may not turn any more sharply. This is because when the watercraft is sliding there is
less water going into the jet intake, and steering thrust is reduced because less water is
discharged from the jet thrust nozzle. As a result, the watercraft starts to slow down and turns more gradually. Returning the
handlebars to a less extreme position allows the watercraft to resume normal turning.

Exercise 7: Planing speed operation
Drill 2: Planing speed operation while turning
1. Accelerate to planing speed.
2. Combine right and left turns to make a series of circles and figure eights.
3. Repeat the drill, gradually increasing your speed and making tighter turns. Do not try todo too much too soon.
Tips:
1. Get to know how the watercraft responds at lower speeds before trying to go faster.
2. You can make sharper turns at planing speeds.
3. Remember, as with any motor vehicle, the faster you go, the farther it takes to stop.

Exercise 8: Crossing wakes and swells
You will not always have flat, smooth water to ride on. There will be swells, wakes from
other boats, etc. We cannot give you a drill to practice as in the earlier lessons, but we can
give you some information to help you when you encounter swells and wakes. The best way to cross wakes and swells is with the least jolt to you and the watercraft.
Small swells are not as difficult to cross as larger swells or wakes. Crossing a sharp wake gives more of a jolt than a broad swell.
To cross a wake or swell, change your speed and choose the angle at which you cross
the wake or swell. Usually, a slower speed and “quartering” the wake (crossing at an angle)
will reduce the jolt. Two other things you may notice as you ride.
The first is that crossing a group of wakes or swells is not as easy or smooth as crossing
just one wake. The second is that when you quarter the wake or swell the watercraft will try to steer
away from the wake or swell. When crossing at a 45° angle, you may not notice this, but at a smaller angle, say 10°, it
can be very strong. Be prepared to steer and balance as necessary.
Tips:
1. Grip the handlebars firmly and keep both feet on the floor of the footwell at all times.
2. Reduce speed before crossing the wake or swell.
3. “Quarter” the wake or swell.
4. When going over wakes, raise your body off the seat slightly and absorb the shock with your knees.
5. Do not operate the watercraft with your chin or chest right above the handlebars. It is possible for the operator to hit his or her ch est or jaw on the watercraft body or handle-
bars and be injured.
6. Do not operate in rough water.
7. Do not operate in bad weather.

Exercise 9: Operating with passengers
Objective:
This exercise lets you practice operating the watercraft with passengers on board.
Skills:
Boarding with passengers, and maneuvering the watercraft with passengers on board.
Directions:
The heavier the total weight of the operator and passengers, the more difficult it will be
to balance the watercraft.
Maximum load
Do not operate the watercraft when the total weight exceeds 240 kg (530 lb) including
any cargo.
Drill 1: Boarding, accelerating and maneuvering with passengers on
board
1. Board the watercraft as noted in Exercise 3, and sit astride the seat.
2. Grip the handlebars with both hands and place both feet on the floor of the footwell.

Exercise 9: Operating with passengers
3. Have the passenger get on board and sit astride the seat. If additional passengers aregetting on, have them follow the same procedure.
4. Make sure all passengers are properly seated with their feet in the footwell and that they are securely holding on to the person in front of them or to the handgrip provided.
5. Attach the engine shut-off cord to your left wrist, and then install the clip to the engine shut-off switch.
6. Look in all directions, start the engine, and then start off slowly.
7. Practice accelerating, turning, and stopping to get accustomed to how the watercraft handles with passengers on board.

Postscript
Watercraft operation requires common sense and good judgment, as well as skills and
knowledge that are learned as riders become familiar with the craft. Although practicing the
exercises contained in this book helps you learn needed skills, you should be aware of your
limits and stay within them as you continue to develop your abilities.
