Description
COLREGs shouldn’t feel like memorising a textbook at 2am.
This app helps you learn and retain the Collision Regulations by combining the official COLREGs wording with interactive visual trainers and knowledge checks that make the rules click in real situations.
What you’ll get
- Official COLREGs text for fast, reliable reference when you need the exact wording
- Interactive learning tools that turn tricky topics into simple visual exercises:
- Navigation lights & day shapes (with time-of-day and visibility/fog scenarios)
- Light sectors & arcs (so you actually remember what “112.5° / 135° / 225°” looks like)
- Narrow channels guidance (keep to starboard—see it, don’t just read it)
- Traffic Separation Schemes (practice crossing angles close to 90°)
- Overtaking recognition (overtaking sector made clear)
- “Action to avoid collision” practice (bold, early alterations made obvious)
- RAM / restricted operations patterns (e.g., dredging with obstruction)
- Knowledge checks & quiz prompts to lock in what you’ve learned and spot weak areas quickly
- Designed for quick sessions—ideal for revision, refreshers, and building confidence before being assessed
- Works great offline for study anywhere
Ideal for
- Students and exam candidates (sailing, power, commercial)
- Skippers wanting a fast COLREGs refresher
- Anyone who prefers learning by doing rather than rereading rule paragraphs
