Polyline Industries is a privately owned plastics fabrication company founded in 1999 by David Wilkie
and David Law.
Polyline first targeted the underground mining sector and introduced a number of unique products into the
industry including Polyduct, Plastic Detonator boxes, Poly Pump floats and an underground poly pipe
welding system to name a few. This product range as well as others is now standard issue in most
underground mines.
Expanding into the marine sector, Polyline introduced a number of plastic commercial boats into the
arena, and is currently leading the world in design, functionality and standards, for polyethylene vessels.
Polyline has achieved the highest survey standards in Australia in a plastic vessel as well as the largest and
the only offshore Polyethylene Rig mounted vessel in the world.
Polyline was named in the top 20 builds of 2008 in ‘Work Boat World’, an international commercial
boating magazine for its’ 6.3m Work Response Craft and has continued to lead and develop new and
exciting products.
Polyline was named again in the top 20 builds of 2009 in ‘Work Boat World’ for its’ two sister ships
the 10.2m YIKARA and the 10.2m PIPARN.
With the company positioning statement “Engineered Polymer Solutions” Polyline has ventured into
Polyurethanes, Rotational molding and of course our range of fabricated products produced from
engineered plastics.
With continual investment in our products Polyline now boasts CNC routing capabilities as well as 4m
butt welding and sheet bending equipment.

Polyline Industries Pty Ltd is
a plastics fabrication company based in
Jandakot Western Australia.
Manager/Director, David Wilkie
has developed an interest in using plastics for marine
applications, including boats, which stems from his
background in aquaculture and marine biology.
According to David, “Polyethylene is an excellent material
for building boats”.
WHY PLASTIC ?
IN, PARTICULAR POLYETHYLENE
Polyethylene (PE) is inert (i.e. the molecular structure is full)
and therefore will not rust or corrode and does not suffer from electrolysis.
As polymers are long chain molecules they give plastics a memory resulting in high impact resistance
unlike metals or glass which have crystalline type structures that dent or fracture.
PE has a low friction co-efficient (0.02) which results in less drag, making for better performance.
PE is relatively light with an S.G. of 0.92, approx 1/3 the weight of aluminium (S.G. 2.7)
PE will not scratch or damage other vessels or
infrastructure. It is lightweight which results in
the boat being very positive in the water as it
naturally floats. Vessels built of PE can be
three times as thick as aluminium for the same
weight or built much thinner and lighter.
UV stabilisers can also be added to ensure a
long working life.
Vessels constructed of PE do not require
coating or painting, and are low maintenance
as the PE is inert and therefore has no porosity
ensuring that marine growth can not penetrate
the polymer. Although marine organisms like
to grow on polymer they can not effectively
attach or penetrate making them easy to
remove and therefore anti foul is not required.
Rotationally moulded PE vessels are limited by
mould design and in size by the oven size and
typically do not exceed 5 meters.
Fabricated PE vessels are limited only by
budget and imagination.

The RIB Market
Polyline Industries’ polyethylene boat revolution
Initially supplying a variety of plastic products to the mining
industry, Western Australian Polyline Industries is now
pushing ahead with new technologies in the boating market.
Their style of fabrication lends itself to the building of much larger
vessels with the conventional frame and stringer techniques
employed in the aluminium boat building industry. The thick poly
hulls at less weight are proving to be exceptionally tough, making
ideal workboats with an extended working life. With attractive
qualities for commercial consideration, and being less than one third
the density of aluminium, Polyline are able to increase the thickness
of the plate three times whilst still maintaining less weight overall.
Although still considered an unusual material to build boats
from, the long list of attributes of polyethylene is fast making it a
preferred choice. The immediate benefits of polyethylene (PE) are,
in effect, the inherent disadvantages experienced with both
aluminium and fibreglass vessels.
The full molecular structure of PE means that no porosity or
osmosis occurs with the material. As such, this inhibits the ability
of marine growth to penetrate or attach.
A low friction co-efficient (slipperiness) of 0.02 results in
reduced drag and better performance. With a specific gravity of
0.91 – 0.97, this material is lighter than water, so, happily, you
know it will always float. The inert quality of PE has the huge
advantage of eliminating the electrolysis and corrosion that are the
bane of aluminium and steel boats.
Polyline’s boat construction combines fabrication from
high-density PE sheet and Roto-Moulded components. This enables
the flexibility of ensuring the strength required in a variety of hull
sizes, and a quality finish in a cost effective time frame.
These hulls now range from the 4.5-metre conventional hull
to the larger eight metre POLYRIB. Polyline is currently
exploring even larger designs, to the 9-metre and 12-metre
marks, with present designs suited for both protected and open
waters. Large, conventional-style mono hulls and Cats are also
on the agenda.
The ‘POLYRIB 8000’ (pictured) is a robust workhorse that was
recently developed by Polyline with glass windows and a pair of
86kW four-strokes. Designed by Steve Bruyn and built by Polyline,
the vessel has a length of eight metres and a beam of 2.5 metre. It
has a cruise speed of 22 knots (maximum 35 knots) and a cruise
range of 100 nautical miles. Electronics include a Raymarine A3
sounder and GPS as well as a Navman VHS radio.
Designs are simple and practical. They feature a big anchor bin
in the bow, extra storage under the bow seat, and large side pockets
for gas bottles (up to G-size). There are a number of lockers across
the transom, a shade over the main deck area, and built-in twin
fuel and freshwater tanks.
The floatation tubes on the side ride high out of the water at
speed and give exceptional stability at rest, even with the
maximum payload of 3,000kgs. These tubes form a squared-off
bow above the water line that provides additional buoyancy where
it’s needed and also presents a useful area to shunt other boats or
work platforms around if required.
As Western Australia’s leading plastic boat builder, Polyline
currently has achieved the highest level of survey for a plastic
vessel, to 2C specifications.

Advances in RIBs and RBBs
Plastic fast rescue craft for offshore industry
David Wilkie of Polyline High-Density Hulls is claiming a
world-first: the oil and gas industry’s first fast rescue craft in
plastic. Specifically, in high-density polyethylene – a material
his company has been using for several years to build RBVs.
Pontoons are rotomoulded in 10mm material, the hull and side
plates are fabricated in 15mm, frames in 20, engine beds in 30 and
water jet intakes in 40 for an extremely tough structure. In another
first, this is the first vessel to have such fabricated plastic intakes.
Mr Wilkie says the Vermillion Oil Company had been searching
the market for the ideal vessel for some years. This first Polyrib
5300 FRC will be stationed on the ‘Wandoo B’ platform on
Australia’s North West Shelf off Dampier, and Mr Wilkie is
confident it will be the first of many in the industry.
Still under construction, the five-person FRC is 6.3 metres in
length with a 2.4 metre beam. The buoyant pontoons are
D-section, giving a greater internal beam than a similar-sized RIB.
Propulsion will be by a single 172kW Yanmar diesel driving
through a Hamilton water jet.
The Steve Bruyn design has a deep-V hull for operations in a
wide range of sea conditions and projections are for a speed in
excess of 37 knots in low to moderate seas. This excellent result for
a two-tonne (light) boat with the available power is partly due to
the low friction coefficient of water-lubricated polyethylene.
Advantages claimed – and proved – for polyethylene include
absence of corrosion, great fatigue and impact resistance, and a
memory that essentially makes the craft bounce rather than take a
dent on impact. Since colour is carried through the thickness of the
material, abrasion (rare because of the) slippery nature of the
material) is not unsightly. Major damage can be readily repaired.
Vermillion engaged IAS Marine as consultants to procure the
most suitable craft for the task. Simon Mathams of IAS researched
worldwide all current and projected designs, and the capabilities
and technologies of builders of that class of vessel. He reports his
unconditional endorsement of the Polycraft.

Ensign tenders tough in and out of the water
Boat owners tired of making repairs to
their damaged and scratched tender
vessels have a new champion in the form
of the sturdy, go-any-where Ensign™.
Made from the same polyethylene
thermoplastic used in bullet-proof vests, the
Ensign™ range is virtually indestructible
and unsinkable, having been subjected to
rigorous testing.
Since its launch by The Haines Group
in July 2007, the Ensign™ has proved
popular for tender applications because of
its unprecedented strength and ability to
cut through rough chop effortlessly.
The Haines Group Managing Director
(Sales and Marketing) Greg Haines said the
design of Ensign™ vessels allowed for
exceptional stability and easy entry and
exit to the water.
www.kirbymarine.com
“The Ensign™ range is built to marine
survey, US Coast Guard and CE
certification standards.
“These boats are positively buoyant and
impervious to osmosis and corrosion,
making them far superior in quality to
most aluminium boats.
“Because these boats are virtually
unsinkable, the Ensign™ range are safer than
the alternative tender vessels, such as
inflatables and RIB boats,” Greg Haines said.
The range of cost effective, high quality
and hard wearing boats has been in
production for over 20 years; used in
adverse conditions by recreational users,
government departments and pearl divers.
The addition of Ensign™ boats to The
Haines Group complements its already
extensive line-up of fishing and lifestyle
boats, including Signature, Seafarer and
Traveler fiberglass boats.

After ten years service Vermillion Oil and
Gas decided it was time to upgrade the
fast rescue and recovery craft on its
platform, ‘Wandoo B’, off Australia’s
northwest coast.
Basically, they wanted a vessel that was
virtually indestructible, fast and versatile.
They wanted a fast vessel that could also be
used for towing in addition to other rescue
and general work boat duties. In fact, they
were looking for a fresh new, innovative
design and were unable to find anything
on offer.
Vermillion then approached David
Wilkie and his partner David Law at
Polyline Industries at Jandakot and
discussed exactly what the specific
requirements were.
Polyline, which has been building
robust work boats since its formation in
1999, immediately sourced a suitable
design from Steve Bruyn of Bruyn Design
and set about doing what its team
30 May 2009 AUSMARINE
Page 30
members enjoy doing best, building a
polyethylene work boat to the exact
requirements of the customer.
Vermillion Oil and Gas was very
specific; it wanted a tough boat that could
support maintenance on the field’s CALM
Buoy-Export Loading Terminal, with the
power and strength to tow the export
floating hose in slight to moderate seas
and the capability to stop it fouling.
Vermillion noted that this had, in the
past, involved using other support vessels
from Dampier Port, with added expense
and time.
The craft also had to maintain fast
rescue and recovery capabilities in the
event of a maritime emergency, and be
capable of being launched and recovered
by hook from the platform.
Other considerations included low
maintenance, durability, reliability and
economy, and in all these fields the
completed Polyline vessel excelled.
Using much the same construction
methods as for an aluminium vessel, the
Polyline polyethylene workboats have “D”
section external pontoons, and ‘Wandoo B
Craft No. 1’ features a deep “V” hull shape
to facilitate the chosen propulsion chain
and to facilitate open water operations.
In this case, the builder and owner
opted for the reliability and performance of
a HamiltonJet HJ 241 water jet powered by
a 179kW Yanmar turbocharged diesel. This
combination delivers the required top
speed, a satisfying 35 knots, in fact, as well
as outstanding manoeuvrability and
performance. They chose a ZF gearbox, and
the vessel’s cruising speed works out to an
economical 26 knots, all achieved and
easily maintained on trials.
She has a surprising bollard pull
capability of 800 kilos, suitable for towing
the hoses when required, and can easily be
launched and recovered from her central
lifting point.
The completed vessel has a loading
dock at the stern for loading casualties,
and carrying a stretcher in the open deck.
The controls and electronics are basic,
sited in a centre console abaft the central
quick release structure.
The vessel looks business-like and
powerfully impressive with her basic black
polyethylene hull complimented by her
high visibility orange sides and uppers.
Those at Vermillion Oil and Gas have
declared themselves totally satisfied with
the finished vessel, which has been out
working off ‘Wandoo B’ since August 2008.
They have stated that: “Polyline proved to
be the right choice in undertaking this
project right through from the conceptual

stage to completion. They undertook and
executed the contract in a professional
manner, retaining maximum flexibility
during the design and construction stages
to incorporate improvements and
enhancements to the craft as they became
evident during the project’s progress.
“Polyline proved both professional
and ethical throughout, with open
communications at all times, and with any
required modifications and variations
quickly implemented to both parties’
satisfaction. We (Vermillion Oil and Gas)
were invited to all tests and trials with
Polyline going to great lengths to ensure
that the whole build was transparent.”
Praise indeed for this innovative
Western Australian Boat Builder.
Polyline Managing Director David Wilkie
has an impressive career at sea, beginning
as a marine biologist active in fish farming
and aquaculture, and also as a practical
seaman. He readily understands the needs of
his clients, and now has considerable
enthusiasm for the many advantages
of polyethylene boats, and knowledge
and experience of their construction.
He combines this with an educated
understanding of the needs and operations
of the oil and gas sector in particular.
Polyline began building boats ten
years ago, and at one stage branched out
into the manufacture of polyethylene
industrial and mining equipment and
supplies. But, from 2003, the company’s
major focus has been on building tough,
durable, high-performing work boats, and
doing that in some style, confidently
looking forward to being numbered
among the best in the field.
Polyline is currently perfecting a
revolutionary self-righting system for its
vessels and has recently been building a
bigger vessel than ‘Wandoo B Craft No.1’, a
6.6-metre vessel with a more general purpose
emphasis, including a fully enclosed lifting
frame, and lower sides allowing for overside
rescue work to be carried out, showcasing the
company’s abilities.
With an enviable order book, Polyline
is currently also building two ten-metre
line boats for Port Headland, and with
the company’s expertise, enthusiasm,
and professionalism, the future looks
bright indeed.
In conclusion, what better praise could
you wish for than Vermillion Oil and
Gas’s closing statement: “‘Wandoo B
Craft No.1’ has proved to be a quality
vessel that performs all duties and tasks
better than expected. Vermillion Oil and
Gas Australia would have no reservations
in recommending Polyline to any
company wishing to purchase a similar
vessel or pursue a development project
with their organization.”

Polyline Industries of Western Australia
claims a fistful of firsts for their ‘Polyrib
6300 WRB’.
The world’s first polyethylene craft to be
based on a platform, the first waterjet-diesel
in its size range, the first waterjet
installation to use a plastic jet intake, and
the first and only combined fast rescue
craft-workboat built in Australia.
An impressive list, but more significant
is that Polyline has built a vessel that has
proved ideal for its job. They have coined a
name for the new type: Work - Response
Boat or WRB.
Vermilion had the required fast rescue
boat on station on the Wandoo B
platform, but found, as most operators do,
that there was little rescue work for it to
do. There was plenty of demand for it,
though, as a workboat – a role for which it
was not optimised. Vermillion, therefore,
commissioned IAS Marine to research the
workboat-FRC concept worldwide.
The result was the acceptance of
Polyline’s ‘6300’, a Steve Bruyn design,
subject to a great deal of testing. This
included drop and brake tests at 50
metres/minute at full load plus ten
percent, which Polyline extended to 60
metres/minute.
The vessel’s design is essentially a
self-draining rigid buoyancy (RBB) centre
console boat, constructed entirely from
polyethylene: high density (HDPE) for the
fabricated hull and deck, medium (MDPE)
for the fendering system.
The all-plastic structure was a major
attraction of the ‘Polyrib 6300’. Besides its
impact resistance, its freedom from
corrosion or any other kind of decay meant
near-zero maintenance requirements, and
hull maintenance is difficult to carry out in
the stowed position.
With 6.3 metres in overall length, the
‘Polyrib’ has a 2.5-metre beam and is
powered by a 178kW Yanmar 4LHSTP from
Power Equipment, driving a HJ241
Hamilton waterjet. The maximum speed of
35 knots is well in excess of specifications,
due to the low friction of polyethylene.
This applies both to water flow past the
hull and through the jet intake.
Overall efficiency is impressive too. At 22
knots, fuel consumption is only ten litres an
hour, giving a 14-hour or 300nm endurance.
Since most of the vessel’s work involves
line handling, bollard pull was important
– something not usually associated with
waterjet FRCs. The ‘Polyrib’ produces 0.8
tonnes of bollard pull, and is equipped
with a pair of towing points for mounting
a bridle.
Suiting the workboat role, the ‘Polyrib’
has been given high sides for dryness, and
deck space for uncluttered working. For
adapting to rescue, the console has been
located to give enough room ahead of it for
securing a stretcher. The aft rails and
seatback rests remove to allow the stretcher
to be pulled through and forward.
Polyline has built large numbers of
commercial vessels, as well as patrol
and oil spill response vessels, and all have
demonstrated to their owners the
toughness and miniscule maintenance
requirements of polyethylene. Its low
friction means what are usually abrading
impacts are barely noticeable on the
fendering. Hard impacts are normally
bend-and-rebound affairs, and severe
penetrating impacts are readily repaired.
Adding to the practicality of the ‘Polyrib
6300’, its 2.5-metre beam means it can
be towed on the road without permits
or restrictions.

Making waves with polyethylene
Having served their apprenticeship in
the fabrication and supply of a variety of
plastic products to the mining industry,
Polyline Industries is now making waves
in the marine industry.
Although still considered an unusual
material with which to build boats, the
long list of attributes of Polyethylene is fast
making it a preferred choice. The
immediate benefits of polyethylene (PE)
are, in effect, the inherent disadvantages
experienced with both aluminium and
fibreglass vessels.
For example, PE has a full molecular
structure, and this means that no porosity
or osmosis occurs with the material. As
such, this inhibits the ability of marine
growth to penetrate or attach, so
antifouling is not required.
A low or co-efficient friction
(slipperiness) of 0.02 results in reduced
drag, and better performance. With a
specific gravity of 0.91 – 0.97 this material
is lighter than water, so it will always float.
The inert quality of PE has the huge
advantage of eliminating the electrolysis,
corrosion and rust that aluminium and
steel boats experience.
Aluminium and fibreglass also have a
crystalline-type molecular structure that
allows them to dent and fracture. Polymers
are long chain molecules that give plastics
a memory and high impact resistance, so
dents last only as long as it takes to back
away from the offending jetty or rocks.
As the colour penetrates right through
this UV stable material, painting is not
required, and maintenance is reduced as
scuffing or scratches are barely evident.

And the range of colour choice
combinations is almost as extensive as a
paint colour chart, even including a glowin-the-dark material, if that’s what floats
your boat (so to speak).
Polyline's boat construction has a
process of a combining fabrication from
high density PE sheet, and rote-moulding
the small to medium-sized components.
This enables the flexibility of ensuring the
strength required in a variety of hull sizes,
and a quality finish in a cost effective time
frame. These hulls now range from 4.5
metres to the larger eight-metre polyrib
with a cabin, and with a maximum beam
of 2.5 metres, these craft are all still
trailable. Polyline is currently exploring
even larger designs, to the nine-metre and
ten-metre mark, with current designs suited
for both protected waters and ocean going.
The Polyrib 6200 (pictured) is a robust
workhorse that was recently delivered to the
DPI Environmental Protection unit. With a
centre console and targa bimini cover, it is
similar in design to polyribs supplied to the
Fisheries Department, and Dampier Port
Authority. Both low maintenance and
tough, the polyrib design is proving to be a
reliable commercial vessel, and a popular
recreational fishing vessel.
And the design is simple. A big anchor
bin in the bow, large side pockets for up to
G size gas bottles, three lockers across the
transom, a bimini cover over a centre
console that has both a weather proof seat
locker, and large rear locker for fire and
safety equipment storage. The floatation
tubes on the side ride high out of the water
at speed, and give exceptional stability at
rest, even with the maximum payload of
2,000kg. These tubes form a squared off
bow above the water line, that provide
both additional buoyancy where it’s
needed, and also presents a useful area to
shunt other boats or work platforms
around if required.
As WA's leading plastic boat builder,
Polyline currently achieves the highest
level of survey for a plastic vessel, to
2C specifications.

Perth Company Builds Worlds’ First, World Class
10.2m Polyethylene Pair of Workboats
In the face of the current economic downturn, W.A. Company Polyline Industries Pty Ltd, a small
privately owned business based in Jandakot has just built two of the Worlds’ first, World class 10.2m
Polyethylene (plastic) workboats for GO Marine. To-date Polyline has supplied polyethylene vessels to
the Federal Governments’ Patrol Vessel Walcott Tender, the state D.P.I. Marine Safety - Environmental
Protection, W.A and interstate ports and harbour authorities, the Oil and Gas Industry off the North West
Shelf and local commercial fishermen. In January 2009, Polyline was voted one of the Top 20 Builds of
2008 by an international boating magazine “Work Boat World” for its’ PolyRIB 6300 Work Response
Craft – the worlds first polyethylene work response boat.
In October 2009, Polyline released another of its’ World Firsts – two 10.2m Work Boats.
• The “PIPAN” vessel will be used for in-harbour work.
• The “YIKARA” vessel (with cabin) has been surveyed to 40 nautical miles off shore to
enable personnel transfer to and from oil rigs off Port Headland.
WORLD FIRSTS
• At 10.2m these are the largest Polyethylene boats ever built.
• They have attained the highest level of Survey for a plastic boat in Australia, from both:
• The W.A. Department of Transport, and
• The customers’ independent surveyor from Lloyds Register of Shipping.
• They also have the biggest conventional hull for a Polyethylene boat ever built.
The boats were designed by Bruyn Design a very well respected local Naval Architect. They are
powered by 440Hp Turbo Diesel Yanmar Engines driving Hamilton Jets, supplied by local businesses,
Westjet and Power Equipment Supplies.
Manager/Director, David Wilkie has developed an interest in using plastics for marine applications,
including boats, which stems from his background in aquaculture and marine biology.
According to David Wilkie, “Polyethylene is an excellent material for building boats and amongst its’
many advantages, this product has the smallest carbon footprint of any commercial means to produce a
boat, making it extremely environmentally friendly”.
ADVANTAGES OF POLYETHYLENE
• Polyethylene does not corrode, oxidize or suffer electrolysis unlike aluminium or fibreglass.
• Polyethylene does not require painting and as the colour is permeated through the whole product and
it will always look clean even when scratched.
• Polyethylene is comprised of long chain molecules which contain a memory which allow it to flex
on impact and return to its original shape after a collision. In layman’s terms “impact resistant”
means the product will not crack, fracture or dent.
• As Polyethylene is inert, it can not be chemically attacked so antifouling is not required.
• The SG (Specific Gravity) of polyethylene is 0.96, less than water so it will always float.
• When welded polyethylene does not give off any fumes and even when burnt polyethylene only
produces CO2 and H2O. There is nothing carcinogenic ensuring that our workers health is secure,
unlike workers with aluminium or fibreglass.
ADVANCES
We have upgraded from single to dual outboards
and we are now producing fuel efficient boats
with Turbo Diesel Engines driving water jets and
have had enquiries for larger twin engine, twin jet
rescue vessels. Both Chevron and the Gorgon
Project have shown great interest and we have
tendered for both. We have an environmentally
friendly product that is stronger and more flexible
than anything else on the market, is safe for those
who work with it, costs the owners less to
maintain, floats in any circumstance and has the
smallest carbon footprint of any commercial
means to produce a boat.
PUSHING THE LIMITS
We believe that Polyline is today, where the
Aluminium boat industry was 30 years ago, but
with a better, more durable material in
polyethylene. We are continually pushing the
boundaries and as yet, have not found our
limitations. As aluminium boat builders have
done with aluminium, Polyline Industries could
potentially do the same with polyethylene. Due
to the increasing acceptance of polyethylene
boats, and the growing demand, especially for
the Gorgon Project Polyline is extremely well
positioned and is on the brink of creating a new
World Class industry in Polyethylene boats, in
Perth Western Australia, even during this current
economic down turn.

Polyline, specialists in High Density
Polyethylene (HDPE) construction, have
delivered two 10.2-metre line boats to Go
Marine of Port Hedland.
Polyline vessels have typically resembled
RBBs, but these are along the lines of
conventional plate aluminium craft and
were fabricated in much the same way. The
builder is confident that they are the
world’s largest conventional design HDPE
boats. A significant difference between
HDPE and aluminium is its ability to take
up compound curves without the need for
pressing, and the line boats have taken
advantage of this property in their bows.
The sister hulls were given different
layouts. One, intended purely for harbour
work, has a centre console and can operate
under the wharf. The other will have a
secondary workboat role, transporting
personnel and light cargo as far as the outer
anchorage. To suit this, it was equipped with
an open-backed wheelhouse, the glass of
which is glued in place. This is the usual
system on aluminium vessels, but it is the
first time it has been used on a plastic vessel.
Aft of the wheelhouse the aim was to
provide maximum clear deck space; this is
capable of accepting up to six pallets with a
total load of over three tonnes.
The design philosophy was to produce
the simplest possible vessels that would do
the job, making the maximum use of plastic.
Handrails use the material, and so do the
bitts that are also lifting points. Even the
central tow post is plastic. The maintenance
cradles are plastic as well, and these double
as transport cradles. They can be used to
launch the vessels off a flatbed trailer and,
since they float, are easily retrieved. The
vessels’ beam was held to 3.5 metres to
minimise legal restrictions on towing.
The greatest attraction of HDPE to an
owner is the minimal maintenance it
requires, resulting in low whole-of-life costs.
26 November 2009 AUSMARINE
The material is coloured rather than being
colour coated so paint has no part to play.
Corrosion and fatigue cracking are not going
to happen, and normal wear and tear is
generally less than with aluminium. In
moderate impacts the HDPE flexes rather
than bending, and wear from abrasion is low
due to the material’s slipperiness (HDPE is
used for fendering strips on aluminium
vessels because of that property).
Power is supplied by 278kW Yanmar
engines driving Hamilton Waterjets.
Polyline built them special exhaust systems
to suit operations in the high temperatures
Port Hedland specialises in. The bilge
pumps were given extra capacity to convert
the deck wash into a fire pump when
needed. To suit that role, the deck wash
hose has extra length and is carried on a
reel. The bilge manifold is conveniently
under the adjacent coaming.
On trials the Yanmars produced a
bollard pull of 1,870kg, and a top speed of
29.2 knots for a likely cruising speed of 20
knots. They proved extremely fuel efficient,
each burning only 100 litres over the first
seven hours at an average speed of 22
knots, giving a range of over 900nm.
Manoeuvrability was excellent, aided by a
large diameter, specially-fabricated wheel.
Trials were run on a moderate to rough
day, giving the craft the opportunity to
demonstrate typical HDPE behaviour. The
material’s properties meant the ride was
considerably softer than hull form alone
could account for, and the noise generated
by the hull was negligible. Engine noise too
was low, reducing one of the factors in
operator fatigue. Hull form presumably was
responsible for the almost total lack of spray.
