Colregs Boating Rules Of The Road
The International Regulations for Preventing Collisions at Sea (COLREGs) are a set of rules designed to prevent collisions between vessels. They are essentially the ā€œrules of the roadā€ for boats. Some key concepts within the COLREGs include:

Avoiding personal dangers at sea

In order to stay safe at sea, we need to know the risks we are facing and to be aware of any personal dangers we could possibly encounter. Here are six of the most common potential dangers individual crew members should be aware of.

Steel and Aluminium Hulls

The two metals used for hull construction are steel and aluminium. These are both very strong materials and will last a long time as long as they are cared for, which primarily means protecting steel boats from rust and aluminium boats from electrolytic action.

Diesel engine winterisation

An inactive boat engine needs to be protected from corrosion during the winter, caused by the rising humidity levels through the cold months and the salty coastal air.
