Sail With Dan is your essential helm instrumentation for coastal sailing. Speed, course, wind, and your next tack are all visible on a single screen. Built for real sailors, the app provides data exclusively in knots—no tourist units. The app does not use hidden paywalls for basic tools. A single subscription unlocks the complete feature set immediately. WHAT YOU GET Helm Instruments: Live SOG and COG from your phone’s GPS, alongside a dedicated magnetic compass page. Drift Calculation: A single, clear angle (Heading vs. COG) showing the combined effect of wind and current directly at the helm. Apparent Wind (AWA/AWS): A classic i60-style apparent wind instrument and wind dial for quick readability. Marine Weather: 7-day wind and wave forecasts powered by professional models (ECMWF, ICON, ARPEGE, GFS, and regional high-resolution models). Compare models side-by-side with the data source always clearly identified. GOTO & Passage Planning: Plan first, sail later. Whether you are sailing dead upwind, downwind, or under engine, the app automatically draws the optimal beat, gybe, or rhumb line. Smart Shore Check: Automatically prevents planned tacks from being drawn across land boundaries. (Note: does not detect rocks, shoals, or marine traffic). Coastal Distance Boundaries: Visual reference bars at 3, 6, or 12 NM from the OSM shoreline (for spatial awareness, not a legal baseline). Chart Tools: A two-tap chart ruler to instantly measure rhumb-line miles and bearings, plus interactive map objects (tap a buoy or charted area to see its name). Safety Features: An anchor watch alarm to wake you if the boat drags, and a one-tap Man Overboard (MOB) button to instantly mark your last GPS fix and guide you back. Tracks & Logbook: Record your tracks, export them as GPX/KML, and maintain a daily logbook. Includes a private catch log for your fishing trips. Night Mode: A red-on-black interface to preserve your night vision in the cockpit. Languages: Fully supported in English and Italian.

NOT FOR PRIMARY NAVIGATION This application is an aid for situational awareness only. It is not a substitute for official paper or approved electronic navigation charts, a visual lookout, or a dedicated echo sounder. Depth and seabed data (for Europe) are generated via mathematical models, not direct surveys, and must absolutely not be used for shallow-water navigation. You are solely responsible for the safe navigation of your vessel. Technical Note: An internet connection is required to download new map tiles and fetch updated weather forecasts. Recently viewed sea areas remain cached on your phone for offline use.
