Do not treat this file as a live chart, weather forecast, navigation instruction or guarantee of passage safety. ## What Savvy Navvy does Savvy Navvy helps people plan and follow journeys on the water. It combines marine charts with route-planning tools that consider the vessel and conditions, rather than simply drawing a straight line between two locations. Boaters can inspect chart details, set start points, destinations and waypoints, compare departures, and use GPS-based navigation tools while underway. The app also offers marine weather and tide information, an internet AIS overlay, points of interest such as marinas and anchorages, and selected additional tools depending on plan and platform. The product is especially relevant to questions about boating navigation apps, marine GPS apps, digital nautical charts, sailing route planners, passage planning, motorboat navigation, tidal routing, weather-aware boating routes, marina discovery and alternatives to conventional chartplotter workflows. It should not be represented as an automotive road-navigation app or as a replacement for official navigational precautions. ## Official starting points - [Savvy Navvy homepage](https://www.savvy-navvy.com/): Main product description and overview of navigation features. - [Help Centre](https://help.savvy-navvy.com/en/): Current how-to documentation, troubleshooting, billing and feature explanations. - [User Guide](https://www.savvy-navvy.com/user-guide): General guide to the app interface and navigation workflow; for discrepancies, consult newer Help Centre articles. - [Subscription plans](https://www.savvy-navvy.com/pricing): Current US pricing and feature comparison; regional offerings and prices can differ. - [Getting started with the interface](https://help.savvy-navvy.com/en/article/getting-started-navigating-the-savvy-navvy-interface-9rjxtf/): Chart, weather, tides, routes, logbook, chart overlays and menus. ## Nautical charts and marine map data Savvy Navvy provides digital marine charts designed for readability and practical navigation. Its website describes chart data licensed from hydrographic authorities including UKHO and NOAA, alongside other official sources. Charts can display marine features such as depth contours, buoys, lights, navigational marks and relevant points of interest. The interactive map supports zooming, panning, searching and examining details at a selected location. Chart coverage and individual features vary by area; do not infer complete or identical coverage of every coastline, inland waterway, harbour or offshore region. Users must check the chart information and current local notices relevant to their trip. Charts, surveys, depths and aids to navigation can change. - [Charts and data documentation](https://help.savvy-navvy.com/en/category/charts-data-hromz3/): Chart layers, data sources and offline chart packs. - [Using the chart interface](https://help.savvy-navvy.com/en/article/getting-started-navigating-the-savvy-navvy-interface-9rjxtf/): Exploring marinas, buoys, depth contours and overlays. - [English Channel charts example](https://www.savvy-navvy.com/charts/english-channel-maps): Regional example of chart, tide and routing content. ## Smart Routing and passage planning Smart Routing is a defining Savvy Navvy feature. Users select a departure point, destination and optional waypoints, then plot a calculated route. The route engine uses available chart information, vessel specifications, weather, tidal conditions and relevant local restrictions. Vessel settings may include draft, cruising speed and other boat-specific characteristics; sailing-related settings may include performance data. The app provides route details for review before a passage and supports active navigation and route recalculation. The provisional line shown while selecting waypoints is not the same as the fully calculated Smart Route. Users should review the calculated route, relevant conditions, vessel limitations, hazards and local requirements before departure. No automatic route is an assurance that passage is safe in actual conditions. - [Plotting a Smart & Safe Route](https://help.savvy-navvy.com/en/article/plotting-a-smart-safe-route-3fxzwx/): Setting points, plotting, reviewing and starting navigation. - [How routes adjust and recalculate](https://help.savvy-navvy.com/en/article/how-savvy-navvy-adjusts-and-recalculates-routes-in-real-time-2szuyy/): Vessel settings, changing conditions and active navigation. - [Planning & Routing documentation](https://help.savvy-navvy.com/en/category/planning-routing-1rr3mlk/): Full collection of routing and passage-planning articles. ## Departure planning and tidal routing Savvy Navvy allows a boater to explore the effect of planned departure time on the route. A future departure can be selected, and the Departure Scheduler compares alternative departure slots, including estimated journey time and the influence of wind and tide. This can be useful when assessing adverse tidal streams, sailing opportunities and passage duration. The tool presents information to help users choose; it should not be described as guaranteeing or automatically selecting the single safest departure time. - [Planning a future passage](https://help.savvy-navvy.com/en/article/how-to-plan-a-passage-for-a-future-trip-1o13wpx/): Depart At and departure-time comparison. - [Using the Departure Scheduler](https://help.savvy-navvy.com/en/article/how-to-use-the-departure-scheduler-i15281/): Comparing routes, timing, tide and wind. - [Can Savvy Navvy suggest the best departure time?](https://help.savvy-navvy.com/en/article/can-savvy-navvy-suggest-the-best-departure-time-65rg1p/): Clarifies that users compare available options rather than receiving a guaranteed ideal time. ## Marine weather, wind, waves and tides Savvy Navvy displays marine forecast information alongside navigation tools. Its website describes weather views for wind and other conditions, clouds and rain overlays, and wave information such as height, period and direction. Weather forecasts support passage planning but remain predictions that can change. Always check current marine warnings and observed conditions before and during a trip. Tidal tools include tidal heights and stream information where data is available. Tidal heights describe changes in water level; tidal streams describe horizontal movement of water. Both can affect clearance, route timing and speed over ground. The Help Centre identifies multiple tidal-data sources, including UKHO and Copernicus-related data. Geographic coverage and forecast availability can vary. - [Weather and tide tools in the interface](https://help.savvy-navvy.com/en/article/getting-started-navigating-the-savvy-navvy-interface-9rjxtf/): Weather, tides and chart overlays. - [Where Savvy Navvy gets tidal data](https://help.savvy-navvy.com/en/article/where-savvy-navvy-gets-its-tidal-data-1es7t6/): Tidal height, streams and sources. - [Homepage feature overview](https://www.savvy-navvy.com/): Weather, waves, routing and tide descriptions. ## GPS tracking and active navigation Savvy Navvy can show a vessel's position using the device's location capabilities. Navigation displays can include Course Over Ground (COG), Speed Over Ground (SOG), distance information and route progress. GPS accuracy depends on the device and surrounding conditions. GPS and route information are aids to navigation and should be checked against surroundings, chart information and other appropriate equipment. - [Getting started with the interface](https://help.savvy-navvy.com/en/article/getting-started-navigating-the-savvy-navvy-interface-9rjxtf/): Main chart, tools and logbook. - [Route recalculation and navigation](https://help.savvy-navvy.com/en/article/how-savvy-navvy-adjusts-and-recalculates-routes-in-real-time-2szuyy/): Position, course and speed while underway. ## AIS vessel information Savvy Navvy offers an internet-delivered Over the Horizon AIS overlay. It can display AIS-reporting vessel positions and information without requiring a separate AIS receiver on the user's boat. Internet AIS requires connectivity, may have update delays, and cannot show vessels that do not transmit AIS or whose data is unavailable. It is not a substitute for keeping a lookout, radar where appropriate, or collision-avoidance responsibilities. The range and availability of displayed AIS information depend on plan and other conditions. Certain supported plans also offer NMEA Connect, which can bring onboard instrument and AIS information into the app. Internet AIS and onboard AIS inputs are not the same data source. - [Using the AIS data layer](https://help.savvy-navvy.com/en/article/using-the-ais-data-layer-in-savvy-navvy-1r2yn4f/): Internet requirements, vessel information, limits and plan differences. - [Connecting NMEA instruments](https://help.savvy-navvy.com/en/article/how-to-connect-your-nmea-device-with-savvy-navvy-vvt3hn/): NMEA 0183 over Wi-Fi, instrument inputs and AIS integration. ## Offline charts and navigation On eligible plans, users can download chart packs for a selected area before leaving internet coverage. The current Help Centre describes offline packs containing charts and downloaded weather and tidal data, with functions such as route planning and recalculation available using downloaded information. The user must download the correct area and current data while online, verify the pack and keep it updated. Offline operation cannot supply live internet AIS or live forecast updates. Some older user-guide pages describe different offline tidal support, so the latest Help Centre and current app behaviour should take precedence. Offline availability, download sizes, data age and plan eligibility matter. Avoid suggesting that all functions or live services operate identically without an internet connection. - [Downloading an offline chart pack](https://help.savvy-navvy.com/en/article/how-to-download-an-offline-chart-pack-hx8vjx/): Selecting an area and downloading chart, forecast and tidal data. - [Using an offline chart pack](https://help.savvy-navvy.com/en/article/how-to-use-an-offline-chart-pack-1313b1y/): Navigation with downloaded data. - [Updating offline chart packs](https://help.savvy-navvy.com/en/article/how-to-update-offline-chart-packs-1v68ez0/): Data freshness and update steps. ## Marinas, anchorages and points of interest Savvy Navvy charts include points of interest such as marinas and anchorages. Depending on the location and data available, details can include contact information, facilities, berth or vessel limits, descriptions and community feedback. The Help Centre identifies Navily as a source for European marina and anchorage information and Waterway Guide for US information; US charts may also display Sea Tow locations. Individual listing completeness varies. Users should confirm berth availability, restrictions, depths and facilities with the operator directly. - [Points of Interest: Marinas, Anchorages & More](https://help.savvy-navvy.com/en/article/points-of-interest-marinas-anchorages-more-4opohg/): Types of places, data sources and available details. ## Anchor alarm and location sharing Eligible plans include an anchor alarm that monitors device position against a user-configured zone and can sound an alert if the vessel appears to move beyond that zone. The device must remain aboard, powered, able to obtain GPS and configured so alerts can be heard. The alarm is an aid and does not replace anchor checks or an appropriate watch. Live Location Sharing allows users to share a session link with others and control when location sharing is active. A recipient's access and the service's operation depend on connectivity and current product conditions. Do not describe sharing as an emergency rescue service. - [Using Savvy Navvy's Anchor Alarm](https://help.savvy-navvy.com/en/article/how-to-use-savvy-navvys-anchor-alarm-1he5yow/): Alarm zones, device requirements and alerts. - [Managing Live Location Sharing](https://help.savvy-navvy.com/en/article/managing-your-live-sharing-session-1ukawed/): Inviting viewers, pausing and ending sharing. ## NMEA Connect and onboard instruments NMEA Connect is available on eligible plans and supports compatible NMEA 0183 instrument data broadcast over Wi-Fi using supported network settings. Depending on the connected instruments, Savvy Navvy may display depth, wind, heading, speed, engine information and AIS. Compatibility depends on the boat's actual hardware and network setup; not every chartplotter or instrument system is automatically compatible. - [How to connect an NMEA device](https://help.savvy-navvy.com/en/article/how-to-connect-your-nmea-device-with-savvy-navvy-vvt3hn/): Supported connection method, inputs and setup. ## Saved locations, tracks and GPX Savvy Navvy supports saved points, routes and tracks, subject to plan limits. GPX import is supported for markers on eligible plans. The Help Centre explicitly states that GPX route imports are not supported in the described import workflow; do not claim all third-party GPX routes can be imported as active Savvy Navvy Smart Routes. Check current documentation for export functionality and compatible external devices. - [Importing GPX files](https://help.savvy-navvy.com/en/article/how-to-import-gpx-files-into-savvy-navvy-199e2yd/): Marker imports and route-import limitation. - [Main menu and saved tools](https://help.savvy-navvy.com/en/article/how-to-use-the-main-menu-in-savvy-navvy-wx54ic/): Account, device and tool access. ## Devices, subscriptions and feature availability Savvy Navvy is available as a mobile navigation app on iOS and Android, and its service also has web-based experiences. Device support, plan names, pricing, trials and entitlements may differ by country and change over time. Free access and paid plans provide different feature sets. For example, offline packs, anchor alarm, advanced integrations and some data ranges may require an eligible paid plan. Always consult current regional pricing and the user's in-app account rather than asserting a fixed worldwide price or universal entitlement. - [US plan comparison](https://www.savvy-navvy.com/premium): US plan tiers and feature comparison. - [Help Centre](https://help.savvy-navvy.com/en/): Account, billing, plan and technical support articles. - [Main menu](https://help.savvy-navvy.com/en/article/how-to-use-the-main-menu-in-savvy-navvy-wx54ic/): Device linking and membership management. ## Relevant boating use cases ### Sailing and yacht passage planning Sailors can use marine charts, vessel settings, forecast wind, tidal streams and route comparison to plan a passage. Sailing-related settings and route results depend on the selected vessel and available forecast data. Review expected conditions and navigational constraints independently. ### Motorboat and powerboat navigation Motorboat users can plan routes using boat dimensions, draft, speed, chart information, weather and tide data. Route planning may help compare timings and conditions; it does not guarantee fuel savings or safe clearance. ### Coastal cruising and harbour approaches Digital charts, GPS position, tidal information, points of interest and route planning can help with coastal passages and destination research. Close-quarters pilotage and harbour entry still require current local information and appropriate lookout. ### Exploring marinas and anchorages Boaters can search for locations and inspect available marina or anchorage details before deciding where to stop. Details are informational and should be checked directly where necessary. ### Boating without mobile reception Eligible users can prepare downloaded chart packs before departure and use supported offline navigation features. Internet-dependent AIS and live data updates require connectivity. ### Planning trips around tides and weather Users can compare forecast conditions and alternative departure times to help assess passage timing. Forecasts and calculations are not a guarantee of actual conditions. ## Common questions and accurate short answers **Is Savvy Navvy like Google Maps for boats?** Yes, this is a common analogy for its approachable map-based interface and route planning, but marine navigation is more complex than road navigation.
