Avoiding Collisions
The International Regulations for Preventing Collisions at Sea (Col Regs) are a globally recognised set of rules which help to stop vessels on the high seas from colliding with one another .

Anyone responsible for a vessel, from a small sailing boat to an ocean going supertanker, must be able to quickly identify other vessels around them day or night, whatever the visibility. They need to be able to quickly interpret the light signals, sound signals and shapes that help identify the type and size of a vessel, the direction in which it is travelling, who has right of way, and what action should be taken to prevent a possible collision. This is not always easy, especially in crowded coastal waters and harbours. 

Note to U.S. users
The International Regulations for Preventing Collisions at Sea apply to all vessels on the high seas. For vessels navigating the U.S. inland waters, the Inland Navigation Rules apply. The U.S. Inland Rules and the International Rules are broadly similar but there are a number of important differences. Following consultation with U.S. Coastguard officers, Safe Skipper Apps have produced the app Navigation Rules: Inland - for Boating and Sailing which explains the U.S. Inland Rules in detail.

### 1/5 — This is poor value

*2020-05-30*

I must admit did not read the details of this app so partly my fault, I had thought it was a full revision type plan as was £5 and recommended on the Sunsail website, but no it is a very limited guide to only collision stuff. Really poor value for money!!!!

### 2/5 — Sailing school should do better

*2019-10-14*

The information is there, which is great. But every app has the information. It's an app from a sailing school, so I expected a better learning experience. Every light, sound, signal, or day sign has the picture and description together. So, no way to do flashcard type learning. There are tests, but the app connects to a website and all testing has to be done on line. As an app from a school and costing money, I expected flashcarsrds, separated pictures from descriptions, and in-app quizes. All that's here can be found on free apps. I don't recommend spending the money on this and wish I would not have.

### 5/5 — Recommended

*2017-12-05*

Packed with useful information about the Colregs. Good clear graphics and explanations. Test yourself is challenging but helping me with my dayskipper course.

### 5/5 — Good

*2017-11-29*

Fast lookup of rules and regs, safety info. Ideal quick reference as well.

### 2/5 — You can get this information for free.

*2017-08-17*

Don't buy

**Developer response:** Thank you for your feedback. We've taken this essential information, rules & regulations and made it into an app format that allows easy, quick reference, as well as adding unique specially designed explanatory graphics to make the rules really clear. Yes, the basic rules are available elsewhere (for free!) but not in app format that you can easily take with you when out on the water.

### 5/5 — Very useful App

*2017-07-27*

A really useful App that helps both learners and experienced sailors learn about navigation, lights, shapes and Collision Regs.
