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


  1. 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

  2. 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

  3. 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


  1. 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).
    D. B and C
