Engineering
Cresta’s engineers, designers and builders use only the highest quality materials in its engineering components. Cresta employs best shipbuilding practice, and will go above and beyond many internationally recognised standards and regulatory requirements. Utilising innovative and state of the art technology, our engineers move into the world of 3D, so that they can get a real feel for all machinery spaces, service compartments and major components before they are fixed into any vessel. Engineering does not have to be complicated and intimidating for any owner, Cresta’s engineering is user friendly and leading edge.
Cresta Motor Yachts offers a wide range of options when it comes time to select your propulsion package. Be it a conventional shaft drive propulsion, ZF pod drive propulsion or IPS pod drive propulsion, Cresta works tirelessly to predict the performance each package will deliver your vessel, enabling the owner to make an informed decision. Cresta’s relationships with major engine manufactures Cummins, Volvo, MTU, CAT and MAN are mature and well established.
Minimising noise and vibration is paramount to an enhanced experience aboard any luxury motor yacht. All machinery and mechanical systems are resiliently mounted so as to minimise noise and vibration. All mufflers and exhaust tubes are custom made. They are shaped for effective sound reduction and minimal exhaust back pressure. Ultimately any exhaust package will be determined by the propulsion package. All designs direct exhaust fumes away from the vessel, discharging underwater where possible, to reduce the odour in the cockpit and mezzanine areas. We have even catered for placing the engine room fans on speed controllers so they are inaudible at low speeds.
Engine room ventilation offers a quality environment, capable of continuous operation at reasonable and ambient temperatures with minimal salt mist induction. Ventilation is fan forced with mist eliminators on intakes and outlets. Fans are powerful so as to keep the environment positively pressurised whilst at top speed. Keeping the visual aesthetics in mind the engineers and designers work together to create a visually appealing air intake on the hull sides.
All plumbing aboard Cresta vessels are of approved marine type, and use non corrosive materials for the intended purpose. All pipe work is neatly arranged and easily identifiable using colour coding and flow direction adhesive stickers. Throughout the vessel, hull fittings are fitted with clam shell strainers and comply with ISO 9093-1 and ISO 9093-2. Cresta vessel owners need not wait for hot water, the hot water circulation pump makes hot water instantaneous, taking the strain off your onboard desalination unit and the need to carry large volumes of water for longer journeys.
Each Cresta vessel that leaves the production yard is regionally specified. Producing luxury motor yachts for the global market requires engineering to be flexible and dynamic. For example, any local climate will increase or decrease the demands on air-conditioning, which directly affects the size of the generator. Warmer climates like Northern Australia, Singapore, Florida and The Middle East demand more BTUs in an air conditioning system. Cresta installs a fully automated chilled water circuit enabling the vessel to pump cool water around the boat (rather than gas) with each cabin independently controlled.
Engineering can make or break your vessel. Cresta performs the necessary due diligence and uses only the best engineering techniques to ensure that when you step aboard your vessel you can take solace in the fact all systems are of the highest quality and have been designed to comply and surpass internationally recognised standards and regulatory requirements. All part of Cresta’s indelible ethos, “Quality, Workmanship and Dependability since 1965”.
