Power or sail, Knight Marine Electronics Hamble has the knowledge and skills to install the latest navigation and electrical equipment on your boat. In the rapidly changing and innovative world of modern day electronic equipment Knight Marine Electronics ensure that they are fully informed and up-to-date with the latest equipment available.
Integrating your existing system with new equipment is not always a case of “plug and play”, but nor should it become a daunting task preventing you from upgrading or changing systems. Linking chart plotters to radar and autopilots, installing additional repeaters or concealing new cable runs are simple tasks for Knight Marine Electronics engineers.
Providing the power to feed these appliances often requires an upgrade in the battery bank, management, and charging systems. Installing a Mastervolt, Sterling or Victron charging system, wind, sea generators (WATT AND SEA), solar panels, or a combination of all of these is often the answer. Ask us the tech questions and we can provide a solution.


These days, racing and cruising yachts carry a wealth of tactical computer software on board, even in the most simple of systems, providing data such as wind speed and direction, course being steered, tacking angles, speed over the ground, distance to waypoints and marks, tide and tacking angles. Whether you rely on your electronics to help you to win regattas or to cruise quickly and safely to your next port of call, the feedback from your instruments will be at best inaccurate and at worst useless and potentially unsafe unless your electronics have been installed and calibrated correctly. Paul Knight, an experienced, competitive and successful racing sailor, and his team have the knowledge and expertise along with the specialist diagnostic equipment required to carry out a professional calibration on board your boat.

Maintenance and Repair


There may not be a need to throw away that old plotter, or get a new radar system. Your existing systems might just need some TLC and a repair, we will do our best to keep your existing systems running!

Partial and Complete re-wiring services

Sometimes your wiring suffers in the harsh environments we take our boats to, water, heat and other damage to wiring, circuit breakers and switches can lead to equipment failure and worse. From changing a fuse panel or switch to complete re-wiring we can do it using only high quality marine grade equipment.

Communications and Entertainment

Today's sailors expect some of the home comforts whilst living aboard; mobile and satellite phone, WiFi broadband connections and television are all commonplace these days. Irrespective of the size of craft, Knight Marine Electronics will be happy to advise on system selection and installation. Installations of heating systems by Webasto, Eberspächer, Spectra water-makers and microwave cookers often form part of the weekly workload. Knight Marine electronics will ensure that you have the right system for the job.

Let us compile comprehensive systems guides – particularly useful following crew hand over – and maintain your system records. We can also offer calibration and tuition services to ensure the very best end user experience.
