Roger Hill’s latest creation, “Bajaca”, is a twin hull boat built in Divinycell core material, which according to DIAB, is the next-generation stylish family yacht that offers top performance and great fuel efficiency, being light and sleek, it is said to virtually slice through the water, giving a smooth and stable ride.
“Bajaca” is an 18.7-metre power cat that DIAB says will comfortably house family and friends and be perfect for long range cruising and living. Designed by Roger Hill Yacht Design, New Zealand, it was commissioned 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.
Roger Hill has been drawing boats for almost 40 years and approximately 20 years ago, he started designing under his own name. His first boat was the 14.5m planning power cat “Life”. Since then, there has been a steady stream of interesting and varied projects. Given the project goals, it was clear to Roger that the clients needed a semi-displacement hull. Live aboard ability was critical so fuel capacity, water-making ability, power generation, and storage were priorities in the design. Noosa Marine, on the Sunshine Coast, north of Brisbane, Australia, was commissioned for the build, and construction began in June 2014.
Because of previous project experience and construction successes, Roger decided to base the design on ATL Composites DuFLEX composite panels with structural DIAB Divinycell H foam cores. DIAB says its Divinycell 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.
The hull bottoms, lower topsides, chines and engine bearers were cored with 30mm Divinycell H130. For all other structural areas, Roger chose Divinycell H80. Non-structural interior parts were made using lower density Divinycell H60 and H35 cores.
“Construction with DuFLEX makes it possible to achieve required weight, stiffness and stability and optimise fuel consumption without sacrificing comfort or performance,” says Roger Hill. “Using the DIAB foam-cored DuFLEX option saves approximately 2,000 kilograms over more conventional building methods.”
The production is now underway and “Bajaca” will most probably be in the water by late 2015.
