Depth, ground type, 608 shipwrecks and satellite imagery — built from the INFOMAR national survey of 700,000 km² of Irish waters. All offline, so it works with no signal, anywhere you go. Add GPS plotting, tracks, routes, MOB and marks, and the seabed and your boat sit on the same screen. Stop guessing what's beneath you.
One survey, three ways to carry it: the phone in your pocket, a tablet at the helm, or the desktop on the wheelhouse PC.
Always in your pocket — deck, tender, shore, or instant backup if the helm screen dies.
A bigger screen mounted at the helm of RIBs, day-boats and yachts.
The wheelhouse PC on bigger and commercial boats — runs alongside your existing plotter.
Same charts, every screen
Every layer from the INFOMAR survey, bundled offline on the device you already own — no signal needed at sea.
INFOMAR Survey Data
INFOMAR is the most detailed seabed survey of Ireland ever made — twenty years of sonar data from the Geological Survey and Marine Institute. Depth. Ground type. Contour lines down to the metre. It's the best marine data available for these waters, and Maranox puts it on the screen you use at sea.
Colour-coded depth and contour lines around the full Irish coast. The kind of detail a yacht skipper uses to avoid a bar and an angler uses to find a drop-off — same data, both jobs.
Not just how deep — what the bottom is made of. Mud, sand, gravel, rock, or mixed. Matters whether you're shooting gear, anchoring for the night, planning a dive, or picking a wreck. And it's already on the chart for the whole Irish coast — no sounder, no surveying, not just where you've already been.
Slide between sediment colours and depth contours. See where sand meets rock, where the ground drops off, where the good tows are. All in one view.
Download the charts once on Wi-Fi. At sea, everything loads from your device — no internet, no buffering, no signal needed. Use the phone app on deck or the desktop app in the wheelhouse.
Shipwrecks & Diving
Geological Survey Ireland catalogued every known wreck in Irish waters. Maranox puts them all on the chart — with the seabed data a dive skipper actually needs to plan the dive.
Wreck position over INFOMAR bathymetry — see the depth, the contours around it, and the terrain the wreck sits on.
Rock, sand, mud or mixed — the sediment layer shows what's around the wreck so you know what visibility and conditions to expect.
Drop marks on your favourite spots — reefs, walls, scenic dives, drift routes. Saved on your phone, always there.
All 608 wrecks are bundled in the app. Seabed charts download once. Works 50 miles offshore.
