Sailing Reference vs Maritime Master

Sailing Reference is the comprehensive reference guide for all of your nautical navigation needs. Ideal for beginner and seasoned sailors, the app contains information crucial to passing the various RYA Yachtmaster shorebased navigation and practical courses. All content is fully available offline so is not reliant upon a data connection at all. There are handy calculators for quickly estimating a course to steer, interpolating tidal stream data, calculating times and heights of tide at secondary ports, and estimating VHF radio transmission ranges. The in-depth reference section includes dozens of illustrated and detailed how-to guides covering: • Plotting a Course to Steer • Calculating Leeway • Calculating Set and Drift • Compass Deviation and Magnetic Variation • Estimated Positions • Interpolating Tidal Streams • Calculating Depth to Anchor • Bridge Clearances • Secondary Port Calculations • Buoyage and Beacons • Safety and Distress • VHF Radio • Weather and Shipping Forecasts • and Many More! For those who need to brush up on their knowledge of the COLREGs / IRPCS, load up the flashcards for a quick quiz. Included with the app are a set of “Rules of the Road” flashcards covering numerous collision scenarios. Additional flashcards covering vessel lights, day shapes, flags and sound signals are available to purchase in-app as a single add-on pack. For the racing community there's a handy race timer with a 5,4,1,0 countdown and lap timer. Also available are instructional animations illustrating how to tie a number of the most common nautical knots. Each knot is accompanied by a brief description outlining suitable applications. The Bowline Knot is included with the main application, with other knots available to purchase in-app as a bundled add-on.

Master COLREGS navigation lights at night with interactive 3D views and a focused quiz mode. Maritime Master – Nav Lights lets you explore realistic navigation light patterns in 3D and then test yourself on vessel type and aspect recognition. Rotate around the ship, see how the lights change with your bearing, and connect what you see to the COLREG rules that define each pattern. Explore COLREGS light patterns Browse a full set of navigation light configurations for power-driven vessels, vessels at anchor and aground, NUC, RAM, mine-clearance, dredgers, tugs and tows, fishing vessels, pilot vessels, air-cushion craft and WIG craft. View each pattern on a dark-hull 3D ship at night and drag to rotate around it to see the lights from dead ahead, bow, beam, quarter and astern. See a clear, plain-language COLREG rule overview for every pattern, linked to Rules 23, 24, 26, 27, 28, 29, 30 and 31. Check exactly which physical lights are fitted with a breakdown of masthead, sidelights, sternlight, towing light and all-round signal lights. Smart reference and search Group patterns by COLREG rule, by vessel size (over 50 m / under 50 m), or browse a simple A–Z list. Use the built-in search to find patterns by name, summary or rule number (for example “Rule 27”, “NUC”, “tug towing”, “fishing trawling”). Night Lights Quiz Practice recognising navigation lights in realistic 3D: each question shows a night view of the vessel from a specific aspect. Choose the correct combination of vessel type + aspect from multiple-choice answers. Use the binocular zoom button to temporarily zoom in on the lights. Get instant feedback: see your score update, and after each question review the correct answer (and your wrong answer when you miss it). Finish the quiz with a clean results screen showing total score and accuracy. Perfect for learners and refresher training Great revision for COLREGS / navigation lights questions in yachting and maritime exams. Helpful for skippers, students, cadets and watchkeepers who want to turn confusing night light patterns into something they recognise at a glance.
