## What is Ahoy?

Ahoy is a pocket field guide for sailors. Pull it out, check, and get back to the water.

The captain says a word you don't know. Lights appear on the horizon you can't identify. A buoy sits off the bow and you can't remember which side to pass. Ahoy answers in seconds.

WHAT'S INSIDE
• Ship Lights: identify vessels at night by their light pattern, shown from every angle as glowing schematic diagrams
• Signal Flags & Marine Alphabet: all 36 flags and their meanings, Alpha to Zulu
• Buoys: lateral, cardinal and other sea marks, with the shapes each mark can take
• Day Shapes: cones, balls and diamonds, and what they tell you about a vessel
• Beaufort Scale: real sea-state photos for every force from 0 to 12
• Clouds: read the sky with photo references and what each cloud means for your weather
• Sound Signals: blast patterns for good and restricted visibility
• Radio Help: ready-to-read VHF scripts for Mayday, hailing a vessel and radio checks
• Dictionary: searchable sailing jargon, from abeam to windward

MADE FOR REAL TRIPS
• Polish and English, following your device language
• No ads, no account needed
• IALA buoyage for your region

AHOY PRO
• A one-time purchase unlocks full offline access, so every reference works with no signal at sea
• Everything else stays free

FOR LEARNERS AND CREW
Whether you're preparing for a recreational licence or joining a friend's boat as crew, Ahoy gives you the confidence to be useful on deck. It won't pretend to replace a course.

Ahoy is reference material for recreational sailing, not a navigation tool. Always verify against official, up-to-date sources.
