About
NauticCalc is a professional calculator for precise nautical navigation at sea. Designed for sailors, skippers and maritime crews, it helps you plan safe routes, correct courses and understand changing conditions. Use NauticCalc to convert between knots, kilometres per hour, metres per second, miles per hour and feet per second. Switch depth units between metres, fathoms and feet, and handle distance in nautical miles, metres and kilometres with confidence. Plan your voyage with accurate course calculations. Adjust compass headings for deviation and variation, and apply wind and current corrections to keep your vessel on track. Estimate arrival times using distance and speed so you can manage watch schedules and harbour approaches. Work with wind in Beaufort, kilometres per hour, metres per second and knots. Assess sea conditions, choose suitable sail plans and prepare for regatta or cruising passages. Combine speed, heading and drift to understand the effect of current on your track. NauticCalc supports everyday coastal sailing as well as longer offshore trips. Use it alongside your paper charts, electronic plotter and logbook to cross check bearings, positions and routes. Whether you sail a small boat or a large yacht, NauticCalc gives you clear, reliable calculations to support safe and efficient navigation.
