It can be very easy to confuse (or forget) what particular lights, marks and shapes mean - especially when you are stressed, or it is dark. With this handy Reeds Handbook, help is quickly at hand! The guide is laid out simply and clearly for ease of use, enabling crew, navigators, skippers and even casual day guests aboard to quickly identify, the lights, marks and shapes being displayed by other ships at night as well as during the day.

These lights, shapes and marks are applicable worldwide by maritime law, which makes this international handbook a valuable and popular addition to Reeds series of handbooks.

Information includes:

Cardinal buoys and channel markers.
Daytime shapes displayed by boats (e.g. for anchoring, towing, diving, dredging).
Lights displayed by ships at night (tugs, dredgers, pilot vessels, stationary vessels, fishing boats, yachts, motorboats) and from all aspects (front, side, astern).
Ships' sound signals (used in fog).
Signal flags and their navigational meanings (I am dragging my anchor; You are running into danger; I have a diver down).
