Boat electrics, done to the standard.
Modern yachts are no longer 12V batteries and a bilge pump. They're integrated networks of power and data, and they need to be designed, installed and fault-found as a system. ABYC-certified marine electrical work for cruising and racing boats on the east coast of Ireland, from Dermot Tynan and Kalopa Robotics Limited.

What we work on
From a single intermittent fault to a full winter refit of the electrical system.
Lithium (LiFePO4) power
Insurers and surveyors are rightly strict about lithium. LiFePO4 systems designed and installed to ABYC E-13, documented, and safe to leave unattended.
- System audit and load analysis
- BMS, DC-DC and alternator protection
- Victron, Mastervolt and similar ecosystems
- Lead-acid to lithium conversions
NMEA 2000 & instrument networks
When the instruments stop talking to each other the fault is rarely the display. It's the network. Root-cause diagnosis rather than swapping parts until something works.
- NMEA 2000 / 0183 backbone design and repair
- Intermittent data drops and conflicts
- AIS, autopilot, plotter and VHF integration
- Wi-Fi bridging and remote monitoring
Solar & off-grid power
Live at anchor without running the engine or a generator. Charging systems sized and installed to actually keep up with the fridge, the autopilot and the laptop.
- Solar array sizing and MPPT integration
- Inverter/chargers and shore power isolation
- Battery monitoring and alerting
- Galvanic isolation and bonding
Also: general DC/AC fault-finding, rewiring and panel upgrades, pre-purchase electrical surveys, and tidying up the “previous owner” wiring.
Engineering discipline, applied to boats
The marine electrical work here is carried out by Dermot Tynan, a lifelong sailor, ABYC member and certified marine electrical technician, through Kalopa Robotics Limited. Kalopa is a Dublin engineering company that designs autonomous sailing vessels, which is a fairly unforgiving test of whether an electrical system can look after itself offshore.
Behind that sits decades of building and running large-scale systems where failure wasn't an option. The same discipline goes into every boat we work on: fault-tolerant power architectures, clean data networks and proper documentation, so that what's on the boat matches what's on the drawing.
- ABYC certified Installations to the same standards insurers and surveyors reference.
- Root cause, not parts-swapping Systematic fault-finding so the problem stays fixed.
- Documented hand-over Wiring diagrams, settings and a written description of what was done.
- Tracked from first call to sign-off Every job gets a ticket; you'll always know where it stands.
Let's talk about your boat
Whether it's a fault that needs tracing or a refit you want engineered properly from the start, get in touch. A short description of the boat and the problem is enough to begin.
