Lazy Skipper

Lazy Skipper is an offline handbook and toolkit for sailing skippers and Day Skipper students. Everything works without signal: on the water, in the marina, in the exam room. HANDBOOK • VHF & distress: MAYDAY, PAN-PAN and SÉCURITÉ scripts line by line, with your vessel and position filled in; DSC, false alert, MAYDAY RELAY, channels, prowords, all Annex IV distress signals. • Yacht anatomy: an interactive 3D sloop. Tap any part to learn its name and what it is for. • Buoys & marks: IALA regions A and B with topmarks, lights and what-to-do diagrams. • Lights, sounds & rules: 39 COLREG light configurations with night views, sound signals with playback, rules of the road explained by situation. • Chart symbols: a guide to the symbols that matter to a yacht, plus the full US Chart No. 1 index. • Knots with step-by-step figures, ICS flags, NATO phonetics and Morse. • Weather: Beaufort and Douglas scales with illustrations, synoptic charts, tides and streams, winds of the world, forecasts by radio. TOOLS • Under-keel and under-bridge clearance, anchor rode length, with diagrams that move with your numbers. • Light builder: place the lights you see at night and the app names the vessel. • Morse and maritime alphabet translator with audio. • Magnetic variation from the compass rose to today, with course conversion. CHECKLISTS Yacht check-in and check-out, overnight, morning departure, under way, crew briefing, with a critical-only mode. Ukrainian and English. Free. No accounts, no ads, no tracking.
