About us
Sydney sailors, working on Sydney boats
7Seas Marine Electronics is based in Mosman and works on vessels across Sydney Harbour, Pittwater and offshore — from weekend cruisers to boats lining up on the start line.
Our approach
We install what we'd trust on our own boat
Marine electronics only earn their keep if they still work three years and a few hundred sea miles later. That's the standard we hold every installation to — proper cable runs, correctly rated fusing and breakers, connections that won't corrode, and calibration that's actually checked against real conditions, not just switched on and left.
We work directly with owners, skippers and boat builders, and we're just as comfortable retrofitting a 20-year-old cruiser as fitting out a new build or prepping a race boat for an offshore campaign.
What sets us apart
Technicians who are also sailors
We calibrate the same instruments we race and cruise with ourselves, which shapes every install we do.
On-water experience
From harbour racing to offshore passages, we understand how gear actually gets used underway — not just how it looks on a bench.
Multi-brand expertise
B&G, NKE, Victron, Orca, Vakaros and more — we're not tied to a single supplier, so recommendations fit your boat, not our stock room.
Safety-first workmanship
Every install is finished to a standard that will pass a safety or offshore category inspection — because we also carry out those inspections ourselves.
