What this video covers
A yacht captain uses a suite of mobile applications on an iPhone to assist with weather forecasting, passage planning, and marina logistics while sailing in Croatia.0:06 WeatherTrack serves as the primary tool for downloading and interpreting GRIB files, which provide wind, swell, and pressure data.1:29 The captain supplements this with Windy for its visual interface and wind speed interpretations, and YR for general weather trends.5:07 For logistics, MySea and ACI Marinas facilitate berth research and bookings, while RYA Books provides a reference for collision regulations and navigation lights.8:33 Marine Traffic tracks AIS signals from nearby vessels to assist with situational awareness, though the captain emphasizes that it does not replace a visual lookout.11:58 Navionics Boating provides chart data and course plotting, though the captain warns that digital depth and datum information must be verified against paper charts and real-time soundings.13:20 These tools function as assistive devices rather than replacements for traditional navigation and constant vigilance.17:55
