Roger Hill 19m Power Catamaran
Launched December 14 2015, the 18.7 metre Bajaca
designed by Roger Hill Yacht Design, New Zealand, was commissioned by a
Sunshine Coast businessman with a brief for up-to-date styling above the
waterline, self-contained facilities for extended cruising in remote
areas, and the ability to run at 25 knots if required.
those goals in mind, it was clear to Roger that a semi-displacement
hull form would meet the type of boating and performance the clients
were looking for. Live aboard ability was critical so fuel capacity,
water-making ability, power generation, and storage were priorities in
Noosa Marine was commissioned
for the build, and construction began in June 2014. Founded by Julian
Griffiths in 2008, Noosa Marine specialise in custom boat building
services and consult closely with the owners and designers to create a
craft that will suit their needs - a proven formula that will ensure an
outstanding result for this luxury project. Julian has an impressive
portfolio spanning 25 years and has used the DuFLEX System extensively
in many projects, most recently in the construction of the Schionning
Designs G Force 1800 KATO that was launched in May 2014.
of previous project experience and construction successes, Roger based
the design for construction with ATL Composites DuFLEX composite panels
with structural DIAB Divinycell foam cores.
The hull bottoms,
lower topsides, chines and engine bearers were cored with 30mm
Divinycell H130 and laminated with 2 layers of 850grm E-fibreglass
quadraxial. Divinycell H has a proven track record, and its unique IPN
chemical structure, yields impressive mechanical performance making it
ideal for applications subject to fatigue, slamming or impact loads.
panels, cored with Divinycell H80 and laminated with a variety of
fibreglass orientations, were manufactured for all other structural
areas, predominantly in flat panel form, but in some cases, with
unidirectional laminates for strip planking curved sections, to optimise
the engineering and performance in specific areas.
Featherlight panels have been supplied for the non-structural interior
parts, and are cored with lower density Divinycell H60 and H35 cores
laminated with a 600grm quadraxial E-Fibreglass to ensure uniform
stiffness, stability and lightweight. The interior panels will be
finished with a combination of timber veneers, decorative fabrics and
some painted sections.
Roger commented “Construction with DuFLEX
will ensure the required weight, stiffness and stability is achieved to
optimise the performance and fuel consumption without sacrificing
comfort or performance. Using the DIAB foam- cored DuFLEX option has
saved approximately 2,000 kgs over more conventional building methods”
To take full advantage of the DuFLEX Building System, Roger
worked with ATL engineers to supply the design as a CNC-routed kit to
reduce labour and keep wastage to a minimum, and a DuFLEX Z-Press was
supplied to Noosa Marine to join the panels and further speed up the
The design layout was developed closely with the
owners keeping the cabins as large as possible with full head room. The
main cabin/saloon area is open plan with the doors and windows sliding
away to allow entry to the cockpit with no step-over sills, and the
large dining space is easily served from the galley or the BBQ on the
The owner’s cabin is forward, featuring a large
ensuite bathroom, and takes the full width of the starboard hull. The
prime guest cabin also has its own ensuite and the other two secondary
guest cabins share a large, mid-ship bathroom that includes a full-size
domestic washing machine and separate dryer.
The design does not
have a conventional flybridge, but does have a sun-bathing area on the
cabin top where the tender is stored with a davit crane and a
surfboard/paddleboard rack. This cabin top area is also fitted with
large sliding hatches to maximise ventilations and light into the
forward area of the saloon.
The boat will comfortably house family
and friends, and the modern design, extensive entertaining both inside
and out, luxurious interior, and a cruising speed of 16 knots will make
it perfect for long range cruising and living.
