Master COLREGS night lights

$1.99 · Designed for iPad

Learn COLREGS night lights with interactive 3D views, quizzes and clear rule explanations. 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.
