MaritimeHub is an offline navigation assistant for mariners and deck officers. It works offline, except for Weather Online, and combines navigation calculators, maps, references and professional maritime tools in one app. Navigation Tools: • ETA Calculator — ETA from current device time or manual departure time. • Required Speed — required average speed for a selected ETA. • Multi-WP ETA — route ETA for multiple waypoints. • Leg Summary — passage analysis: time, average speed, SLIP and more. • Noon Report — Noon / BOSP / EOSP reports. • True Wind — true wind calculation. • Anchor Watch — anchor chain length, swing radius and GPS-based anchor circle monitoring. • CPA Calculator — CPA / TCPA and close-quarters parameters. • Squat Effect — squat calculation underway. • Density Correction — draft correction for water density. • Trim Correction — draft correction due to trim. • Draft Survey — displacement / cargo / constant calculation. • Opposite Draft — hidden side draft and heel/list calculations. • Magnetic Variation — adjust charted variation to voyage year. • Compass Error — gyro / magnetic compass correction, Star Finder, GPS position autofill. • Compass Comparison — compare gyro and magnetic compass headings. • Celestial Navigation — vessel position by three celestial bodies. • Point to Point — course and distance: Rhumb Line / Great Circle. • Coords Converter — DD / DM / DMS coordinate converter. • Unit Converter — maritime and engineering unit conversions. • ECDIS Contours — Shallow / Safety / Deep contour calculations. • GPS Monitor — live GPS position, speed, course, trip distance, average speed. • Roll Meter — live heel, roll period and GM calculation. • Roll & GM — roll period and metacentric height calculations. • Bunker Calculation — voyage bunker planning. • Fuel Interpolation — calculate ROB or fuel consumption at an intermediate event using time-based interpolation. • Blind Distance — blind area under the bow and propeller immersion. • Propeller Distance — distance run by propeller RPM and time. • Simplified ECDIS — simplified ECDIS simulator. References & Maps: • CATZOC — depth uncertainty calculation by CATZOC category. • Sun Times — sunrise, sunset, twilight, time zones + GPS autofill. • Moon Phases — moon phase reference. • Meteo Scales — Beaufort scale and weather reference. • Cargo Ventilation — cargo ventilation assessment. • Dew Point / Humidity — dew point and relative humidity. • NAVTEX Stations — interactive NAVTEX station map + GPS vessel position. • e-NP & ADRS Areas — e-NP, ADRS, ATT and ADLL areas with GPS position. • ECA, PSSA & Special Areas — interactive environmental, particularly sensitive and special area maps. • Routeing & Security Charts Areas — weather routeing and security chart coverage. • NAVAREA Regions — interactive NAVAREA map + GPS position. • Load Line Zones — Load Line zones + GPS position. • IALA — IALA buoyage system Region A/B + map. • Route Checker — check a planned route against e-NP, NAVAREA, NAVTEX, IALA, ADRS, ECA, Special Areas, PSSA, Load Lines, Routeing and Security Charts. • GMDSS Advisor — estimate VHF/MF/HF radio range and find practical MF/HF DSC test stations. • ICS — International Code of Signals. • Ports — ports database (~7,244) with coordinates and UN/LOCODE. • Country Flags — national flags. • World Time — world time zones, including DST. • Tidal Curve — intermediate tide height calculation. • Online Weather — online weather by PassageWeather.com. • GRIB Builder — build weather overlay requests for ECDIS. • Morse Code. • COLREG 72 — COLREG 72 with illustrations and annexes. • Earnings — salary calculator: Basic / Overtime / Leave Pay and more. All calculators support print / export to PDF or directly to a printer. MaritimeHub is a practical all-in-one toolkit for navigation, calculations and maritime reference at sea.
