If you are responsible for a vessel at sea, no matter how small or large, you must be able to recognise different types of navigation marks, day or night, and know what they mean.

This Buoys & Lights app will help improve your overall boating skills and safety on the water.

Buoys & Lights is designed to help all recreational and professional seafarers learn and understand the world buoyage systems which are organised by the International Association of Lighthouse Authorities (IALA).

There are two systems in use, IALA A and IALA B and they are both explained fully in this app.

There are 4 main sections in this boating safety app:

1. Buoyage: A graphic reference guide with 70 illustrations and captions which explain the different types of buoy, their uses, appearance, permutations and light characteristics.

2. Lights: A graphic reference guide with 12 illustrations and captions which explain the different types of light and their characteristics, used by beacons and lighthouses.

3. IALA Rules: The International Association of Lighthouse Authorities (IALA) rules are reproduced in full.

4. Test Yourself: Two quiz sections with a series of multiple choice questions - over 40 graphic representations of buoys and lights helps you check your knowledge.

We've worked hard to uphold the highest standards of accuracy in this app and want you to enjoy this app in several ways:

- As an easy reference and revision tool
- As a powerful visual aide-memoire
- As an accurate source of safety information tested by marine experts
- As a way to constantly improve your knowledge and recall via the 'test yourself" section
- As a tool to assist you on sailing and boating courses
