Plan from shore · Worldwide positions

Trip planner.
Three map views.

Switch between three map views, then match the position format and units used aboard. Salinity accepts decimal degrees, degrees with decimal minutes, or degrees-minutes-seconds, in either latitude-first or longitude-first order. Positions remain WGS 84 underneath. Hold for half a second to place each point, undo, edit, check nearby context, and export GPX.

This browser draft stays in this browser and can export GPX. Positions are stored as WGS 84 and route bearings marked °T are calculated as true bearings; Salinity does not silently substitute magnetic variation or another datum. The planner offers three map views: a full-cover NOAA Marine chart, USGS Satellite imagery, and NOAA BlueTopo Relief shading. Account and app mark synchronization, regulation checks, fuel forecasts and collaborative editing are not part of the planner. These map views, the regional ETOPO estimate, and nearby tide-station data are reference aids—not certified navigation charts or safe-clearance data.
