also have a rear lounge they could use
while fishing and a walk-through for
good access aboard at night.
Recently, I had the pleasure of
water testing this newcomer from the
Land of the Long White Cloud. It’s a
good looking machine finished in dark
blue and white and made a nice trailer
package with its Aussie-made Dunbier
Our test boat was supplied by the
Corrimal branch of Hunts Marine that
is specialising in the Extreme range.
The package retails for $58,840,
which seems pretty good value. It
includes hydraulic steering, Lowrance
HDS7 sounder/plotter and all fishing
Design: The Extreme 570 Game King
is a striking-looking beast on her trailer.
The lines are nicely balanced and have
a hint of the classic game boat with
an up-swept flared bows and a deep,
20-degree deadrise bottom.
What I also like is the way the
hardtop ‘shed’ seems to grow naturally
out of the low, wedge-like cuddy cabin.
It’s a beautiful piece of design work and
really makes the Extreme 570 look a
serious offshore boat.
The problem with putting hardtops
on boats this size is the added weight
they place high up, however, in this
case clever design ensures the hardtop
doesn’t add any unnecessary weight.
The hull itself measures 5.75m
overall including a small snub bowsprit
and bow roller.
Like many Kiwi boats the deep Vee
bottom doesn’t have strakes so the
hull just slices easily into the water at
speed. However, you do get aggressive
‘reverse’ angle chines to help sit the
boat up on the plane.
Unlike the bigger Extreme models
the boat doesn’t come with self-draining
floor as standard, though this is an
option if you really want it. Personally,
I think it works well with the existing
setup as you’ve got plenty of cockpit
freeboard to fish the sides in safety.
With a beam of 2.2m she’s not
overly a wide boat for her class, yet
she achieves quite good stability due
to a wide waterline beam and having
water-ballast. The latter is a Kiwi
invention and provides stability without
any loss of performance. A central
compartment fills with water ever
time the boat is launched. This water
automatically dumps within seconds
once the boat goes on her trailer, or lifts
at speed onto the plane. The concept is
now well understood by Aussie boaties
since we have it on local designs like
the Bar Crusher.
Back aft you also find a full-depth
motor pod to support the heavier
four-stroke motors. Here you’ve also
got landing platforms either side of
the motor well and a folding stern
ladder. The latter looks a looks a little
agricultural but it certainly does the job.
Stepping into the Extreme 570 via
the stern doorway you find a roomy
cockpit with a tough checkerplate floor
and high coamings to keep you safely
in the boat.
Under the floor you have three
large sealed buoyancy chambers to
help keep the boat afloat if she is ever
swamped. Some builders make the mistake
of fully enclosing the wheelhouse,
however, the Extreme has an ‘open
backed’ hardtop so you really good air
ventilation and also excellent rear vision
from the driver’s seat.
Structurally, the Extreme 570 is
very impressive craft and features hull
bottom thickness of 5mm and 4mm
side and deck panels. There is also box
structure internal framing and the whole
boat is computer cut to give extremely
I might mention another version you
can have a soft-top version of this boat.
This is the Sport Fisher version and
may appeal to those buyers who still
prefer the open-top layout. Personally,
I like the hardtop because it great
sun protection and with side opening
windows to keep you cool.
Another surprise with the Extreme
570 is the overall weight. Dry trail weight
