PATHR is modern marine navigation built to make boating simpler, safer, and more fun. Plan your day on the water with smart routing, real marine chart features, weather overlays, AIS awareness, harbor discovery, social sharing, trip tracking, and tools built around how boaters actually move. Whether you are planning a quick cruise, exploring a new harbor, checking conditions, or building a route around your vessel’s limits, PATHR helps bring the whole boating experience into one simple app. Smart Routing Built Around Your Boat PATHR supports both automatic and manual route planning, with routing that considers your vessel profile, including key specs like draft and operating limits. Instead of treating every boat the same, PATHR helps you plan routes that make sense for your vessel, your conditions, and your trip. Our routing experience is designed to help boaters move with more confidence by considering depth, hazards, navigable water, and practical route behavior, not just drawing a straight line from point A to point B. A Better Marine Map Experience PATHR combines high-resolution marine depth data, NOAA chart features, depth contours, aids to navigation, buoys, beacons, lights, wrecks, soundings, bridge clearance data, shoreline detail, and seabed overlays to help with anchoring decisions. The result is a map that feels intuitive, useful, and purpose-built for the water. Important marine information stays front and center without overwhelming the screen. Weather and AIS Awareness View weather overlays while planning and navigating so you can better understand what is happening around you. PATHR also supports AIS overlays, helping you maintain better awareness of nearby vessel traffic. With premium collision-awareness features, PATHR can help identify potential traffic conflicts and give boaters an added layer of situational awareness while underway. Manual Route Planning When You Want Control Prefer to build your own route? PATHR gives you manual routing tools so you can plan exactly where you want to go. Drop points, shape your route, and build a trip that matches your knowledge, comfort level, and local conditions. Explore Harbors and Share What You Find Discover new harbors, anchorages, marinas, and points of interest. Leave reviews, share helpful notes, and learn from other boaters who have been there before. Found a tricky entrance, a great dock-and-dine spot, a quiet anchorage, or something other boaters should know about? Add a map report and help improve the experience for everyone on the water. Social Boating, Built In Boating is better with your people. Add friends, see their location when they choose to share it, send routes, compare adventures, and stay connected on the water. Track your trips automatically and build your own boating logbook over time. Save your routes, review your history, and yes — brag a little. You earned it. The more you sail, cruise, explore, and contribute, the more you can unlock through badges, achievements, and community features. Track Every Trip PATHR records your boating history so you can look back at where you went, how far you traveled, and what you discovered along the way. Whether you are keeping a personal logbook or sharing highlights with friends, your time on the water becomes part of your story. Prop Test Tool Running an adjustable propeller or dialing in your boat’s setup? PATHR includes a prop test feature to help you capture performance data and better understand how your vessel behaves. Built for Real Boaters PATHR is designed for boaters who want powerful tools without the clunky, outdated experience marine software has had for too long. We are building a smarter, cleaner, more connected way to plan, route, explore, and share time on the water. From trip planning to route building, from harbor discovery to social sharing, from weather awareness to vessel-specific routing, PATHR brings the boating experience together in one app. Boating, simplified.
