OpenSeaMap vs Marinate

OpenSeaMap is a worldwide Opensource-project for creating a free nautical chart. Founded in 2009 the project gained a lot of attention lately adding more and more nautical information for free. Not even lights and other nautical infos are provided, but also more and more info layers like weather data, information about harbours and so on. As an add on to the OpenStreetMap this provides all missing info for nautical activities. OpenSeaMap is part of OpenStreetMap and uses the same database. FEATURES: - Free worldwide sea chart (incl. HD chart graphics) - Search for geolocations worldwide - Chartplotting with continuous tracking - Waypoints can easily be created, edited, deleted & exported - Mark locations in the chart - Zoom chart optically to fit your preferred reading size - Enter coordinates directly to be displayed in the chart - Offline caching of up to 1 million map tiles - Cleanup of chart cache data at any time To ensure future development and support of the OpenSeaMap app we encourage you to buy the In-App-Product "PRO". This will help keeping new updates and features coming. DISCLAIMER: OpenSeaMap is part of the OpenStreetMap and uses the same database. As an experienced navigator you should NEVER rely your descisions on one source of information alone. Please keep in mind that the OpenSeaMap can not replace official sea charts on bord of your boat. Please use the OpenSeaMap app only in conjunction with official sea charts and conforming to national and international regulations. Please recognize that no depth information is provided by this product. IMPORTANT: The continued use of the GPS can significantly decrease the battery level.

Marinate is the chartplotter that works when nothing else does, no signal, no marina wifi, thirty miles offshore. Download your cruising area before you slip the lines and the whole app keeps working: charts, routes, depth shading, reference tables. Nothing phones home mid-passage. No account, no sign-up. Open it and you are navigating. WORLDWIDE CHARTS, NOT CHART PACKS Every coast on earth is included. No region to buy, no chartbook to add, no upgrade when you cruise somewhere new: the Aegean this summer and the Caribbean next winter on the same subscription. • Seamarks, buoys, lights, depth contours and soundings as vectors, sharp at any zoom • A fraction of the storage image tiles need • Download by area or along a route corridor 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 and the phone in your bunk. If the boat drifts outside the circle it raises a continuous siren, not a single polite notification. We spent the most time on this, because a dragging anchor at 3 a.m. is when an app either earns its place or does not. SAFETY, NOT UPSELL Man overboard is one tap: a marker, the frozen position, and range and bearing back to it. MOB and the anchor drag alarm are free forever. NEW TO CHART SYMBOLS? Tap any buoy, beacon or light and Marinate says what it is in plain language: which side to leave it, which side to pass, what Fl.G.4s means. DEPTH YOU CAN READ AT A GLANCE • Global depth shading and contours: the blue gradient showing the bottom rise long before a sounding does, worldwide and offline • Seabed relief shading for the shape of the ground beneath you • Optional NOAA overlay in US waters, high-resolution survey depth in European seas SATELLITE AND HYBRID Satellite imagery of the whole planet, plus 10-metre coastal imagery for reading an anchorage before you commit: the sandy patch, the weed, the reef edge. Hybrid mode lays roads and place names over it. 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 to swap with any other chartplotter MARINAS AND WHAT IS ASHORE Search marinas and harbours by name or near you, details kept offline: berths, fuel, water, contact. Search around your anchorage too: fuel, chandlery, pharmacy, supermarket, bus stop, by walking distance. A REFERENCE THAT KNOWS THE SEA Collision regulations in plain language with diagrams, code flags A to Z, day shapes, night lights, sound signals, IALA buoyage, emergency card. All offline, in your language. WEATHER, TRAFFIC AND FISHING • Live rain radar, so you see a squall coming and reef before it arrives. Free, no account • Wind forecast, pressure isobars, tides and currents • Shipping lanes and restricted areas you can tap to see what is restricted and why • AIS traffic (with a free aisstream.io key) • SignalK connects the boat's instruments (depth, wind, speed) with a shallow-water alarm • Sea-surface temperature and plankton layers: fish hunt the fronts and plankton edges, so look where the colour changes FOUR LANGUAGES English, Hebrew, French and Spanish, including the reference tables and the collision rules, not just the buttons. FREE AND PREMIUM Free forever: charts, GPS, routes, tracks, markers, MOB, anchor alarm, rain radar and one offline area. Premium adds depth shading and contours, satellite and official chart overlays, wind and pressure, sea temperature and plankton, AIS, SignalK, unlimited offline downloads and the extended forecast. 14-day free trial, with special launch pricing, 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. Terms of Use: https://getmarinate.com/terms.html
