HIGH-PERFORMANCE

BOAT HANDLING

1. What does the term
   “chine walking” mean,
   and why is it a potentially
   dangerous handling
   problem at speed?
   A. Chine walking
   means the boat
   moves back and
   forth from fore to aft
   excessively; this can
   cause pitching and
   potentially stuff the
   bow into a wave.
   B. Chine walking
   means the boat
   rocks side to side
   at speed due to a
   variety of reasons;
   if left unchecked as
   speed rises, it can
   become excessive
   and violent enough
   to cause loss of con-
   trol and potentially
   barrel-roll (capsize)
   the hull.
   C. Chine walking is
   when the boat
   walks home without
   engine power after a
   rough day at sea.
   D. None of the above


2. What could cause
   poor boat handling at
   high speed?
   A. Crossing wakes at
   the wrong angle,
   at high speed, and/
   or with improper
   engine trim angle.
   B. Engine/drive trim
   elevated out too far.
   C. Worn engine mounts
   and loose steering
   connections.

D. All of the above

E. B and C

3. Trimming the drive
   too far under at speed
   can cause:
   A. Poor tracking and
   heavy bow steering.
   B. Loss of speed and
   fuel efficiency.
   C. Potential for stuffing
   the bow into oncom-
   ing waves.
   D. None of the above
   E. All of the above


4. A good tip in learn-
   ing how to handle a
   high-performance boat
   at speed without induc-
   ing chine walking or
   similar oscillation is to:
   A. Increase speed and
   positive drive trim
   only in small incre-
   ments as you master
   and control the hull.
   B. Gently put the boat
   into a slight right-
   hand turn to coun-
   teract the torque of
   the right-hand rota-
   tion of the propeller,
   thereby keeping the
   boat on an even keel
   as you raise speed
   and trim angle.
   C. Practice when
   there’s a slight wind
   chop to break up the
   surface tension.
   D. All of the above
   E. None of the above


5. At high speed, you’re
   approaching another

boat from behind and

want to cross its wake.

What action do you take?

A. Check the trim angle

and lower it slightly;

reduce speed.

B. Approach the boat,

then quickly cut the

wheel left, crossing

the wake immedi-

ately behind it.

C. Approach the boat

at steady, reduced

speed and level

trim, then cross the

wake at an angle,

giving plenty of

room between the

boats.

D. Approach at full

throttle, and trim

and jump their wake

to give a good show.

E. A, B and D

F. A and C

6. After a full-throttle
   pass, to slow down you
   should:
   A. Chop the throt-
   tle suddenly and
   swiftly.
   B. Trim down slightly
   and put the boat into
   a sharp turn.
   C. Reduce trim and
   throttle gradually,
   then as the boat
   comes off plane,
   check behind you
   to ensure your
   following wave does
   not come over the
   transom (typically
   on smaller hulls).
