Electronics goes boating Sanctuary Cove, south-east Queensland’s millionaire’s playground, comes alive for four days each year to host one of the world’s most luxurious boat shows. As we marvelled at the jaw-dropping opulence of the craft on display at the Sanctuary Cove International Boat Show, what really stood out was the level of advanced electronics now included in just about every one of siliconchip.com.au those boats. Here Kevin Poulter takes us through just some ofJuly it .2010  11 .. Gone are the days of limited instrumentation with hard-to-read dials and gauges. Now it’s all glass, with multi-function LCD panels giving everything from engine parameters, fuel usage, boat speed and electrics through to radar, sonar, navigation (including GPS) and even computer graphics and TV programs if you wish! V isitors from around Australia, indeed the world jet in to see a mouth-watering array of motor yachts and accessories from 424 exhibitors. Anything the mind can conceive for marine is presented to everyone with ‘salt in their veins’. The show’s general manager, Barry Jenkins, said there were close to 200 boats on the water: multi-million dollar super-yachts, sail boats, luxury cruisers and sport fishing boats. If placed bow to stern, these boats would stretch close to 3km. ‘On land, we estimate there were hundreds more boats, mainly trailerable,’ said Mr Jenkins. It’s difficult to describe the atmosphere, with thousands of visitors and small plus large boats many can only dream of, huge temporary halls dominated by electronic gizmos, helicopters ferrying visitors every few minutes – the whole area abuzz with excitement. Thanks to innovative control and harnessing of electrons, life on the water is becoming immensely safer, more relaxed and more fun. Remember when you went fishing and eventually found a great spot or reef where the best size fish were abundant? If close enough to shore, a few landmarks would be noted and visually triangulated for future fishing expeditions. In reality, the ‘guessing landmarks’ location method could be a kilometre or more inaccurate. Now for under $200, a hand-held GPS will locate the position any time within a few metres! And if you are unlucky enough to get into difficulties out at sea, then affordable equipment (EPIRBs, etc) will enable 12  Silicon Chip the Australian authorities to know where you are, again within metres, and the ‘cavalry’ will come to the rescue. At the show, a myriad of brands displayed lighting based on highly efficient LEDs, proven now to be so successful. I looked directly at one bank of LEDs and was so dazzled by their extraordinary lumens, I saw ‘spots’ in my eyes for quite a while afterwards. Electronic gear for marine use has one major difference to land – it must be able to withstand the highly corrosive elements, for example, marine entertainment cannot simply be a car stereo painted white. If you love electronics, the Sanctuary Cove Boat Show is the CES on water. There is a feast of all things electronic, such as: • A huge diversity of navigation and depth-sounders – some with the ability to display the engine’s instruments, selectable through a menu and/or via touchscreens • Broadband radar (that the US Military would not approve for sale to private boaties until a detection system was devised) • Autopilots • Thermal-imaging cameras for night vision • Pure sinewave inverters • LED lamps for above and below the waterline • Desalination systems • Cooking systems – full kitchens • BUS / CAN technology • Communications and on-board audio/video entertainment gear siliconchip.com.au Today’s power and sailing boats are the epitome of luxury and comfort, with equipment only dreamed of until a few years ago. And thanks to competition between (mainly) Chinese manufacturers forcing prices down, all this is becoming more and more affordable for even the average boat owner. • • • • Electronic anti-fouling and anti-corrosion All manner of instrumentation and fly-by-wire control Joystick control of stern-drive engines and side-thrusters Winches that raise and lower anchors at a flick of a switch (no longer the domain of motor yachts but expected by many trailer boat owners too) • Zoned air-conditioning and • Advanced refrigeration In today’s supersonic-pace world, nothing should surprise electronics users. While one company is saying ‘it can’t be done’, another is releasing the technology. iPad marine mount low as US$50 each. Given that the iPad was not released in Australia at the time, how was this Aussie coup achieved? An iPad was purchased in USA and the holder ‘mould’ machined on an Australian CNC machine. As a specialised product, demand will be a relatively small, so for around $250, every one sold will be custommachined on the CNC! When these holders are seen, consumers will adapt them for many other uses, in the home and other non-marine applications. The holder offers security and convenience – removing the iPad is a breeze, just unclip it and take it with you. www.shopoma.com.au For example, during the show, Apple’s iPad was a week away from arriving in Australia, yet a ‘world’s first’ iPad mount was displayed by a talented Queensland engineer, Gary Pacey. The Outback Marine Australia holder enables the iPad to be mounted on the boat’s bridge or bulkhead, as a back-up navigation aid plus access to all the features iPad offers, like messages, weather updates, video, music source and OMA’s custom holder for the new iPad which surfing the web. Maps can be as is individually CNC-machined to order. siliconchip.com.au Chinese value Most of all, the quality and finish of boat electronic installations often surpasses those in fabulous homes. If there is something you need to make your boat more attractive or functional – it’s available – and prices have plummeted. Traditional high-quality electronics manufacturers are finding strong competition from Chinese production, with prices as low as ten percent of similar European products.
