MaritimeHub analisi dell'app per 3 maggio

MaritimeHub is a complete offline navigation toolkit for mariners and deck officers. It works fully offline (except Weather Online) and combines essential calculators, tools, and reference pages in one app. Navigation Tools: • ETA from Now — ETA from current device time. • ETA from Set Time — ETA from a custom date / time. • Multi-WP ETA — full route ETA for multiple waypoints. • Leg Summary — passage analysis: time between dates, average speed, SLIP, and more. • Noon Report — reports: Noon / BOSP / EOSP and other formats in a consistent layout. • True Wind — true wind calculation. • Anchor Length — anchor chain length and swing radius estimation. • CPA Calculator — CPA / TCPA and related close-quarters parameters. • Squat Effect — squat calculation while underway. • Draft vs Density — draft correction for water density changes (DWA / density correction). • Trim Correction — draft correction due to trim (transfer to marks / perpendiculars). • Draft Survey — draft survey calculation (displacement / cargo / constant, depending on input). • Opposite Draft — opposite side draft / heel (list) related calculations. • Magnetic Variation — adjustment of Charted Magnetic Variation to the Voyage Year. • Coords Converter — Degrees / Degrees+Minutes / DMS converter. • Unit Converter — common maritime unit conversions (speed, length, pressure, etc.). • ECDIS Contours — Shallow / Safety / Deep contour calculations. • Point to Point — course & distance (Rhumb Line / Great Circle), intermediate points for Great Circle Route. • Compass Error — gyro / magnetic compass error & correction calculations, Star Finder, supports auto-filling latitude/longitude using the device GPS. • Celestial Navigation — determine the vessel’s position using three celestial bodies. • Navigation Mode — live GPS position, speed, course, trip distance, average speed. • Roll Meter — live heel monitoring + automatic roll period and metacentric height (GM) computation. • Blind Distance — blind distance under the bow + propeller immersion percentage. • Propeller Distance — distance run in nautical miles based on propeller RPM and elapsed time. • Roll & GM — roll period and / or GM (metacentric height) calculations. References: • CATZOC — depth accuracy / uncertainty calculation for any CATZOC category. • Sun Times — sunrise / sunset and twilight for any position & time zone + auto-filling latitude/longitude using the device GPS. • Moon Phases — moon phase reference. • Meteo Scales — Beaufort scales. • Cargo Ventilation card — assess when cargo ventilation is needed. • Dew Point / Humidity card — calculate dew point and relative humidity. • Navtex — Interactive map NAVTEX station coverage plus live vessel position from your device GPS (reference). • Navarea — Interactive map NAVAREA regions coverage plus live vessel position from your device GPS (reference). • Load Lines — Interactive map Load Line zones plus live vessel position from your device GPS (reference). • IALA — IALA buoyage system (Region A/B) + Interactive map plus live vessel position from your device GPS (reference). • ICS — International Code of Signals. • Ports — ports database (~11,600) with coordinates and UN/LOCODE. • Country Flags — national flags. • World Time — world time & time zones (including DST transitions). • Tide Height — intermediate tide height calculations. • Weather Online — online weather view (PassageWeather.com). • GRIB Builder - for requesting weather overlay data for ECDIS. • Morse Code. • Colreg 72 — COLREG 72 with illustrations/annexes. • Earnings — salary calculator (Basic / Overtime / Leave Pay, etc.). • All calculators support printing/export — to PDF or directly to a printer. MaritimeHub is a practical all-in-one navigation assistant built for professionals at sea.
