July 2009 AUSMARINE
A dedicated team of researchers studying the migratory
behaviour of sharks has selected Yamaha four-stroke power
for its primary research vessel.
Operating on the environmentally sensitive Great Barrier Reef,
the low emission qualities of the Yamaha F150 makes this
outboard the perfect choice for the shark scientists.
In a joint programme that involves the Australasian Natural
History Unit, CSIRO Marine Research and Undersea Explorer,
researchers are studying the movement patterns of sharks in the
far northern area of the Great Barrier Reef.
Shark researcher and cinematographer Richard Fitzpatrick's
project involves the tagging and tracking of grey whalers, whitetip
reef sharks and tiger sharks in an effort to better understand their
behaviour and ultimately to protect these species.
The Yamaha-powered research boat is principally used to
capture and then tag sharks. The large tiger capture technique
involves attracting sharks to the side of the boat using bait. As
the shark approaches, a tail clamp is applied to the shark's tail
using a three-metre pole.
Once the shark is captured, it is secured alongside the research
vessel to have a lightweight satellite tag fastened to the dorsal fin.
The tracking pack comprises a satellite transmitter, long life
batteries, aerial and saltwater switch. When the shark's fin breaks
out of the water, a unique identifying code is transmitted via
satellite to a receiving station where the tag's position is
calculated. The research scientists in Australia receive the
positions and plot the shark's movements.
The longest transmission duration to date has been 14 months.
The vast distances travelled by sharks has amazed researchers.
In selecting a Yamaha four-stroke outboard to power the
'Osprey' research boat, Richard Fitzpatrick said that the over-riding
appeal of the Yamaha is that they just go when you need them to.
"When you are chasing a four-metre tiger shark you
definitely need a reliable motor," Richard said. "The reliability is
a major safety factor in the high risk work we do, particularly in
the remote areas of the far northern Great Barrier Reef and the
"The Yamaha four-stroke is powerful, economical and
beautifully quiet, all big plusses for our long days at sea."
In support of the research work being undertaken, the
process has been filmed and made into a documentary series
Prior to specifying a Yamaha outboard for their work, the
team undertook some research of their own on various
outboard brands. They quickly discovered that tourism vessels
and boats operated by Queensland National Parks are mostly
Brett Shorthouse, filmmaker on the research project, added that
past personal experience also played a big part in the decision.
"We've been using Yamaha outboards for nearly ten years on
various work boats," Brett said.
"They have been subjected to a really hard life, enduring
many months at sea in all kinds of weather, both inshore and
offshore. The Yamaha engines have performed flawlessly.
Moreover, the back-up support from Yamaha dealers has been
Commenting on their support of the researchers, Yamaha's
National Sales and Marketing Manager Brett Hampson said that
his company's support of their work was a privilege.
"We're delighted to be playing our part and assisting in this
vital work," Brett said. "Yamaha fully supports any projects that
help conserve and protect the marine environment. It's
extremely important to us and our customers."
Yamaha outboards are available through an Australia-wide
network of authorised Yamaha outboard dealers. All Yamaha
four-stroke outboards are supported with a full four-year
manufacturer's warranty and all two-stroke outboards are backed
by a four-year warranty (standard conditions apply).

Yamaha Powers Vital Shark Research
The low-emission qualities of the Yamaha F150 were important when
choosing how to power the research vessel
Finally, the long awaited Victron Energy Quattro
12/3000/120 has arrived.
Based on the popular Victron Energy MultiPlus
inverter/charger, the Quattro takes integration of on board power
systems to the next level. It offers two AC-inputs and two
AC-outputs. Typically, one of the inputs is connected to the
shore power, the other to the generator. One of the ouputs offers
UPS functionality (always provides power) the other is used for
"non-critical" loads that should only receive power when one of
the AC-inputs is connected to a source.
Operation of the Quattro is fully automatic: as soon as there is
power on one of the inputs, the unit will connect the loads to
this source and at the same time starts charging the batteries.
When both AC-sources are powered down, the loads on the
priority ac-output are powered through the inverter.
In addition to the automatic AC-transfer switching, the
Quattro provides all the functionality of the popular MultiPlus:
pure sine inverter with PowerAssist, parallel connect ability for
high power and three-phase systems, VE.Net communication,
powerful adaptive battery charger and trickle charger. The
following Quatro models are now available:
• Quattro 48/5000/70, Quattro 24/5000/120
• Quattro 24/3000/70, Quattro 12/3000/120
