Its important to have this clear in your mind before heading afloat. Conversely, when we leave a harbour they will be on the opposite side of our boat. On the way into a harbour we will keep the red marks to the left (port) side of our boat. Port is left and associated with the colour red. ![]() I have put the term ‘Port’ in brackets as this can sometimes confuse which side we pass the mark. Red (Port) Lateral Marks (IALA Region A area – “UK”) If numbered, then the numbers increase as you enter the harbour so the lower the number the closer you are to open water. As you head into less populated or shallower areas the marks will reduce in size until you finally meet withies (sticks in the ground usually made of willow).īuoyage and Navigation marks may have numbers or names upon them. Generally, where bigger ships go, bigger buoyage is used. In some places, buoys may be posts or sticks in the ground. ![]() They will mark the sides of our channel and encourage us to stick in the middle.īuoys are anchored to the seabed.

On their site is an interesting document about the history of the systems including permitted sizes, shapes etc. More information if you are boating elsewhere can be found on the Trinity House Website. We will be dealing with the IALA Region A system. There are two systems of buoyage depending on where you are. This blog assumes we are boating in the UK. As seen during the Training Talk, no one topic can cover everything you need to go to sea! References:īefore we discuss colours and shapes of marks we must determine where in the world we are boating. The talks are intended as refresher sessions for some and a springboard into training for others. We are running our Free Training Talks throughout lockdown – please contact us if you would like a link to join us online. Why are buoys at certain locations and what are they telling us? Dom covered this topic during our ‘lockdown’ Training Talks earlier this week. In this blog we will be looking at ‘Buoyage and Navigation Marks’. What do all those buoys and markers mean? ![]()
