Bowmar provides integrated electrical and electronic systems for marine vessels from its Rivergate base, including power distribution, generators, batteries, navigation, communications, alarms and complete vessel system design.
Bowmar advertises Complete vessel electrical systems; DC wiring; generators; shore power; battery systems; electronics; communications; alarms; fire systems; design; compliance. Its workshop, marina base or principal operating location is Unit 9, 17 Rivergate Place, Murarrie QLD 4172. The practical service coverage is Brisbane, Rivergate and marine projects Australia-wide. This company is retained as a commercial marine specialist.
Its normal work may involve workboats, ferries, defence vessels, offshore assets or larger yachts, so the scale and documentation can be different from a small recreational call-out. That distinction is useful in YouSail because a sailor planning a major refit or survey-compliant project may need precisely this level of engineering capability.
Marine electrical systems operate in an unusually harsh environment. Salt, vibration, heat, confined spaces and persistent moisture can expose weak connections and poor installation work quickly. A competent marine electrical job should use appropriate cable, terminals, circuit protection and mounting methods, with cables supported and labelled so future fault finding does not become a guessing exercise.
Keep exploring
Owners should expect the electrician to look beyond the failed component when there are repeated blown fuses, low voltage, unexpected battery drain or intermittent electronics. The underlying issue may be voltage drop, corrosion, undersized cabling, poor crimping, a failing battery, incorrect charging or an overloaded distribution circuit.
Energy-system work should start with a real load and charging assessment. Lithium batteries, high-output alternators, inverter-chargers, DC-DC chargers and solar controllers can move large currents, so cable sizing, fusing, isolation, BMS limits, alternator temperature and fault protection matter as much as battery capacity. A good upgrade should document how shore power, engine charging, solar and emergency starting interact rather than simply adding a larger battery.
Mains AC work aboard a vessel requires particular care because shore power, generators, inverters, neutral-earth arrangements, galvanic isolation and bonding can create safety and corrosion issues that are not encountered in a simple 12-volt accessory installation. Owners should confirm that mains-voltage work is completed and certified by an appropriately licensed electrical contractor and that the installation suits the relevant Australian marine electrical requirements. Electronics installation is also an electrical-system task.
Chartplotters, radar, AIS, autopilot, instruments and engine gateways may share NMEA 2000, SeaTalkNG or NMEA 0183 networks and depend on clean power, correct termination and reliable data sources. A well-planned installation considers network architecture, voltage drop, antenna location, software compatibility and service access rather than treating each display as a stand-alone device.
For a fault-finding job, provide the vessel make and model, battery-bank voltage, symptoms, when the problem occurs, and photographs of switchboards, batteries and equipment labels where possible. For a refit, a useful quote should identify the major equipment, cable and protection changes, whether drawings or circuit schedules will be supplied, the testing and commissioning process, and any work that requires a licensed mains-voltage electrician.
If lithium is involved, ask how alternator protection, charging profiles, battery management, emergency isolation and start-battery interaction will be handled. If navigation electronics are involved, ask whether the existing network and sensors are compatible before purchasing new displays.
Systematically compare interfaces, communication protocols and power/ground characteristics, then bench-test or simulate before final installation — confirm physical connectors, NMEA (0183, 2000) and seatalk compatibility, autopilot control inputs, data sentence requirements, and electrical load/voltage behaviour.

Follow the basic COLREGs: keep a proper lookout, maintain safe speed and steering to avoid collisions, know which vessel ‘gives way’ and which ‘stands on’, use correct lights and sound signals, and keep clear of restricted waters and traffic lanes. Check local harbour rules and AMSA guidance for specifics.

Maybe — it depends. In NSW you often need registration and a boat operator licence for motorised vessels, but many small trailerable sailing dinghies without engines don’t require boat registration or a licence. Check the specific rules for your craft, trailer and engine.

A good float plan and a well-stocked emergency kit significantly improve your chances of a safe outcome when cruising remote parts of South Australia’s coastline. The float plan should give someone ashore all the information they need to find you and raise help if you don’t return; the emergency kit should allow you to stabilise the boat, care for injuries, signal for rescue and survive until help arrives.
