We’re back after a much needed break and looking forward to getting stuck into some great projects.

Here’s a solar upgrade we completed a couple of months ago aboard this brand new Island Gypsy. We installed 1,425W of Jinko solar panels with a Victron SmartSolar MPPT 150/60, fully integrated into the vessel’s existing Victron monitoring system.

More charging from the sun and less reliance on shore power, ready for more time out on the water.

Bookings are filling fast, so if you’ve been thinking about upgrading your boat or getting a few electrical issues sorted before summer, give us a call. We’d be happy to help.

After a busy few months, SeaSpark Electrical is taking a well-earned break while I head up to the Gulf for a fishing trip with my son.

I’ll be back and available from 6 October. I may be a little slower responding to calls and messages while I’m away, but I’ll get back to everyone when I can.

Thanks for your understanding!

Raymarine electronics upgrade completed aboard Slick Cat, a 40 ft Fusion power catamaran

The two ageing Raymarine E120 displays were removed and replaced with dual Raymarine Axiom 2 Pro 12 RVM HybridTouch multifunction displays, along with a new Raymarine radar and transducer.

The existing autopilot was also integrated into the upgraded network, bringing the vessel’s navigation, radar, sonar and autopilot together in one clean, modern system.

A massive improvement in screen clarity, functionality and ease of use, and a much cleaner-looking helm.

A serious helm upgrade for this vessel

The older Raymarine setup was replaced with twin Garmin GPSMAP 1253xsv multifunction displays, a new Garmin radar, GSD 24 sounder module and Fusion entertainment system, while also integrating the vessel’s existing autopilot into the new displays.

To finish it off, we installed a custom-made acrylic dash for a clean, sleek appearance.

The result is a completely modernised helm, with navigation, radar, sonar, entertainment and autopilot control available from either display.

A great week working aboard the beautiful Selene 59 Calypso.

As part of ongoing improvements to the vessel’s 24V Victron lithium power system, we completed a substantial solar upgrade to increase charging performance and off-grid capability.

• Increased solar capacity from 720W to 2145W
• Supplied and installed new Victron MPPT charge controllers
• Expanded the vessel’s existing 24V Victron lithium power system with over 1.4kW of additional solar generation
• Reconfigured, tested and commissioned the complete solar charging system

The additional solar capacity will significantly improve energy independence and reduce reliance on engine and generator charging while cruising.

Always a privilege to work on vessels of this calibre and deliver reliable, high performance power solutions for extended cruising.

This beautiful Hanse 385 suffered a direct lightning strike during the storms earlier this year, leaving some electronics completely inoperative while others lost communication across the vessel’s legacy SimNet network.

Following extensive fault finding, we replaced the damaged equipment and upgraded the vessel to a new NMEA 2000 network, including:

• B&G Zeus3S chartplotter
• B&G WS320 wireless wind system
• B&G Triton² displays
• B&G NAC 3 autopilot system
• B&G V60 VHF radio
• B&G NAIS 500 AIS transponder
• ZG100 GPS and heading sensor
• DST810 depth, speed and temperature transducer
• Complete NMEA 2000 backbone redesign

One of the most heavily affected areas was the masthead wind instrumentation and associated cabling. Upgrading to the wireless WS320 removed the mast data cable, simplifying the network and eliminating a direct connection between the masthead and the vessel’s NMEA 2000 system. While no vessel is lightning proof, reducing conductive pathways can help minimise the likelihood of network equipment being affected by future lightning events.

A great result for the owners and another yacht back on the water with a fully functional electronics suite.
