Marine Electronics Humpty Doo

Boat wiring, batteries, solar, chartplotters, sounders and radios for Humpty Doo boats, installed for Top End salt and heat.

Workshop in Winnellie, on the boat at the marina, ramp or mooring. Free consultation and a written quote before any work.

Humpty Doo is rural — hobby farms, large sheds, water and bore systems, off-grid and partial-grid setups, and a fair number of small businesses run from home blocks. Repair work out here tends to be infrastructure: pumps, gates, controllers, inverters, and comms gear that has to keep running through the wet.
