About Nav Lights - SailVoyager
At night at sea you see lights, not boats. Nav Lights tells you what they are and what to do.
WHICH VESSEL IS IT?
Add the lights you see, one above the other, and whether you can see her red, her green or both sidelights. The app tells you what vessel it is, which side you are looking at, where she is heading and who must give way, with the COLREGs rule and her day shape.
• Power-driven vessels of every length, sailing vessels and vessels under oars
• Towing, being towed and pushing
• Trawlers and other fishing vessels
• Not under command, restricted in ability to manoeuvre, dredgers and minesweepers
• Constrained by draught, pilot vessels, at anchor and aground
When the same lights could belong to several vessels, it shows you all of them.
WHICH BUOY OR LIGHT IS IT?
Type the light as shown on the chart, for example Fl(2) R 6s or Q(6)+LFl 15s, and see the buoy with its topmark, the light flashing with its real rhythm and which side to pass. It reads international and Spanish chart notation.
• Port and starboard lateral marks and preferred channel marks
• North, south, east and west cardinal marks
• Isolated danger, safe water, special marks and emergency wreck marks
• IALA regions A and B
FLASH TIMER
Can you see a light blinking and do not know what it is? Hold the button while it is on and release it when it goes off. The app measures the flashes, groups and period and tells you which mark it is.
MADE FOR THE BOAT
• Red night mode to keep your night vision
• Works offline: no signal needed
• No account, no ads and no data collected
• In English, Spanish and French
FOR YOUR EXAMS
Lights, day shapes and buoyage come up in every boating and sailing exam. Practising with real cases is the best way to get them right.
One-off payment, no subscription. Made by SailVoyager, the online nautical school.
This app is an aid to identify lights and marks. It does not replace a proper lookout, official nautical charts or the COLREGs.
