COLREG Made Easy

COLREG Made Easy is a complete, offline-first reference and study tool for the International Regulations for Preventing Collisions at Sea — built for deck officers, cadets, and anyone preparing for maritime exams (MCA, USCG, STCW, and equivalent national certifications).

WHAT'S INSIDE

• Situations — interactive give-way and stand-on scenarios, covering crossing, overtaking, head-on, and restricted-visibility encounters
• Lights & Day Shapes — visual reference for vessel identification by night and day, from both side-profile and end-on (bow/stern) viewpoints
• Sound & Light Signals — every signal pattern, with offline audio playback so you can study without a connection
• Full Rules Text — the complete regulations, searchable, organized by part and annex
• Quiz Mode — test yourself against realistic scenarios before you sit an exam or a company assessment

BUILT FOR LIFE AT SEA

Every audio file and reference screen works fully offline — no signal required. Study on watch, in your cabin, or between assignments, without worrying about connectivity.

FREE TO START

The three most common encounter types (head-on, crossing to port, crossing to starboard) are free, permanently. Unlock the full set of situations, lights, signals, and quiz content with a single one-time purchase — no subscription, no recurring charges.

WHO IT'S FOR

Deck officers, cadets, and watchkeepers who need a fast, reliable reference they can trust — whether refreshing knowledge before a Flag State exam or double-checking a rule during a watch.

Developed by a working Master Mariner, not adapted from a generic quiz template.
