Design of electrical and electronic systems for new build and upgrade projects. Full documentation is provided which includes schematic, bills of material, installation notes and any programming files necessary. For upgrades and additions a comprehensive survey of existing systems is undertaken to ensure compatibility and safety.

Have us inspect your vessel's wiring and electrical equipment for safety and compliance with ABYC and NMEA standards to ensure safe, reliable and enjoyable boating. You can also call us when things go wrong, or just stop working, and we will diagnose the fault. Any corrective action required will be clearly explained and an estimate provided should you decide to ask us to carry out the work.

Some examples of Our Work


Complete Vessel Electrical Systems

Electrical and Electronic Design and Installation

We can provide the design and installation of all onboard electrical and electronic systems. Equipment from different vendors can be integrated to provide the seamless display and use of data on multiple platforms. Some of the systems integrated on this catamaran include NKE Marine Electronics instrumentation and autopilot, Ocean Data Systems UpsideUp anti-capsize system, Volvo Glass Cockpit MFD, Side Power bow thruster, Harken electric winches and Lewmar electric windlasses.


Authorized NKE Reseller and Installer

NKE Instrumentation and autopilots

Whether you have a performance cruising boat, or are a solo ocean racer, NKE instrumentation and autopilots supply unrivaled performance. We can advise on the best options to suit your application, and are experienced in interfacing the system to other NMEA 0183 and NMEA 2000 network components.

Solar Panels

Custom arrays to suit your requirements

We can design solar panel arrays to suit your energy requirements, space available and likely cruising grounds.


Charge Controllers and Protection Diodes

Blocking and bypass diodes for parallel and series connected panels

The electrical arrangement of the panels is dependent on battery chemistry, battery voltage and panel specifications. The configuration is optimized to mitigate shading effects and ensure as much charge as possible is transferred to the batteries under all conditions. Maximum Power Point Tracking (MPPT) controllers are used to maximize the transfer of energy to the batteries.

Custom Bus Bars and Power Distribution

Networked power monitoring

Bus bars can be custom designed to suit charge and load requirements, and the physical space available. Remote monitoring of current flow, state of charge and battery voltage for multiple battery banks.


Optimized Charging Schemes

Battery chemistry includes LiFePO4, FLA, AGM and Gel batteries

Different battery chemistries require different charge settings. We design systems that optimize the charging of multiple battery types from multiple sources, including solar, engine alternator and other battery banks of the same or different voltage and type. Monitoring and control over a network provides a central place to view the state of charge of all connected sources.
