SEAiq Pilot is designed especially for use by river, channel, and harbor pilots. It includes support for charts in the S-57, S-63, iENC and BSB/KAP formats and use of external NMEA/AIS over WiFi. IMPORTANT: For non-pilots, we recommend SEAiq and SEAiq USA. This app is free to download. All features are available during a 7-day evaluation period. An in-app purchase is required to permanently upgrade the app, otherwise after the evaluation period only basic chart viewing is supported. Features unique to SEAiq Pilot include: * Support for official HO S-57/S-63 marine charts * Adheres to IHO S-52 chart display standards * Predicted vessel display (with ROT) * Docking aids displaying distance/velocity to wharf fenders * Vessel catalog * Supports WiFi based AIS plugs and Portable Pilot Units * NMEA/AIS record and playback * Waypoints, routes, ETA, XTD, speed limits * Route Meeting Point * Visual CPA * AIS "virtual boarding" * Mariners tools: VRM, EBL, Mariners Notes, Clearing Lines Continued use of GPS running in the background can dramatically decrease battery life.
