During a few days we have been working on a 58 m Amels built in 2006. The project has been short and, in principle, not quite glamorous; but it’s a necessary job that is too often overlooked: overhauling and testing of the electronic equipment on board.

Sketch of the yacht

Before the summer season begins (when the boat will be most intensively used) you will surely inspect the engine, the batteries, safety and live saving appliances… Everything must be in perfect condition. But what about electronics? We trust them for any navigation issue, hence we should not forget them when it comes to inspection.

That is why we, at Medenisa, carry out the operation tests and overhauling of the electronic equipment on board. The main goal is to check the whole installation of each piece of equipment: from the antenna downwards to any device, including cabling and connection boxes. Any element has to be checked, to assess that it’s working properly, and that signals reach it as they should. And we have to make sure that, after pressing the ON button, everything is working properly, that is, the equipment does its duty and the screens are displaying what they should.

These tests are specially important if the equipment is going to be removed from its location (e.g. to be taken to the technical service, or to be repositioned, or if the area where it’s placed is going to be painted). Then we can be sure that the equipment was working before it was removed.

What if you don’t carry out the test? Imagine you remove the equipment, and when it’s refitted back in place it’s not working. First you loose a few hours reconnecting again and again, and making sure you did everything OK. If you are lucky, it just shake you up a bit and the equipment will be back again working soon. But what if it doesn’t? It will be impossible to say if it was already out of order before dismantling it, or if it suffered some damaged during removal, handling, storing or reassembling. For sure the issue will arise arguments, annoyance and, at last, some money lost.

Here you can see the main working area in this kind of project: the Top Deck (so often called the Monkey Deck) and the mast for lights and antennas

For the specific superyacht we are talking about, we tested and overhauled all the electronic equipment on board. Most of them can be seen in the picture below:

  • Domes: antennas for Inmarsat and satellite TV
  • Radars
  • Cameras: CCTV and surveillance (thermographic)
  • Antennas: VHF, SSB (Single Side Band), GPS, AIS, terrestrial TV, Navtex
  • Wind equipment
  • Navigation lights and search lights were overhauled as well

So remember, don’t forget to carry out these tests and overhauling at least once a year!
