Marinate is a chartplotter that works when nothing else does — no signal, no marina wifi, thirty miles offshore.
Download your cruising area before you leave the dock and the whole app keeps working: the chart, your routes, the depth contours, the reference tables. There is no account to create and no sign-up screen — open it and you are navigating.
★ OFFLINE VECTOR CHARTS
Seamarks, buoys, lights, depth contours and soundings, drawn as vectors so they stay sharp at any zoom and cost a fraction of the storage that image tiles do. Download by area or along a route corridor. Optional NOAA official chart overlay for US waters.
★ AN ANCHOR WATCH THAT ACTUALLY WAKES YOU
Set your anchor and a safety radius and Marinate watches your position in the background, with the screen off. If the boat drifts outside the circle it raises a continuous siren, not one polite notification. A dragging anchor at 3 a.m. is the moment an app either earns its place or does not.
★ SAFETY IS NOT AN UPSELL
Man overboard is one tap: marker dropped, position frozen, range and bearing back to it. The MOB button and the anchor drag alarm are free forever.
★ ROUTES, TRACKS AND MARKERS
Distance, bearing and ETA at your speed. Record and replay tracks. Markers for anchorages, hazards, dive sites and fishing marks, with photos. GPX import and export.
★ MARINA BOOK
Search marinas by name or near you, import them to your chart, keep the details offline.
★ A REFERENCE THAT KNOWS THE SEA
Collision regulations in plain language with diagrams, code flags A–Z, day shapes, night lights, sound signals, IALA buoyage and an emergency card — all offline, in your language.
★ WEATHER AND TRAFFIC
Live rain radar — see the squall coming and reef before it hits. Wind forecast and pressure isobars on the chart. Tides. AIS traffic. Shipping lanes and restricted areas. SignalK for boat instruments.
★ FOR FISHING
Satellite sea temperature and plankton (chlorophyll) layers with a real colour scale. Bait gathers on the plankton edges, fish hunt the temperature fronts — you are looking for where the colour changes. Plus high-resolution seabed depth in European waters, fishing markers with photos, and replayable tracks.
★ FOUR LANGUAGES
English, Hebrew, French and Spanish — including the reference and the rules, not just the buttons.
PREMIUM
The core app is free forever: chart, GPS, routes, tracks, markers, MOB, anchor alarm, rain radar and one offline area. Premium adds depth shading and contours, official and high-resolution chart overlays, wind and pressure, sea temperature and plankton, AIS, SignalK, unlimited offline downloads and the extended forecast. It starts with a 14-day free trial, cancel any time.
IMPORTANT
Marinate is an aid to navigation, not a replacement for official charts, a proper lookout or your own judgement. Carry the charts your flag state requires. Continued use of GPS in the background can decrease battery life.
Offline charts, an anchor alarm that wakes you, tides, radar and fishing maps.
