Installation & Usage Guide

Installing SeaNav US on your Mac is straightforward, and the process has been optimized for both beginners and power users. Begin by visiting the official Pocket Mariner website and clicking the “Download SeaNav US” button. The download is served over a secure HTTPS connection, and the installer file is signed by Apple to prevent tampering. Once the .dmg file is saved, double‑click to mount the disk image, then drag the SeaNav US icon into your Applications folder. macOS may prompt you to confirm the application’s authenticity; simply click “Open” to proceed.

After installation, launch SeaNav US from the Launchpad or Applications directory. The first run triggers a brief license activation wizard where you enter the purchased serial key. Activation occurs online, verifying your entitlement and unlocking the full feature set. Once activated, the program presents a welcome screen with a quick‑start tutorial that walks you through selecting a chart region, connecting a GPS receiver, and creating your first route.

The main interface consists of a central map view flanked by toolbars for chart layers, navigation controls, and a sidebar for waypoint management. To begin navigating, select the “Chart Library” button, choose a region (e.g., “Pacific Northwest”), and load the corresponding vector chart. Connect your GPS device via USB or Bluetooth; SeaNav US automatically detects NMEA data streams and displays your vessel’s position as a bright, pulsing icon. Use the “Route Planner” to click on the map and drop waypoints, then click “Calculate Route” to generate an optimized path that respects depth contours and traffic separation schemes.

For advanced usage, explore the “Weather” menu to overlay radar and wind data, or the “Tides & Currents” panel to schedule arrivals based on predicted water levels. The application also includes a “Safety Alerts” window that monitors your position against known hazards and issues audible warnings when approaching danger zones. All settings are saved automatically, and you can export routes for use on other devices or share them with crew members via email.
