Towing Alongside over 50 Metres

Please note that it would be perfectly legal for an under-50 metre power boat to display the lights shown below.

However, the lights below are legal for an over-50 metre boat and are based on the “pushing” boat having two masthead lights forward, extra masthead light abaft and higher than the forward ones, port and starboard sidelights, and sternlight.

The boat being pushed alongside just has port and starboard sidelights and sternlight.

Please note that the “Over 50 metres” phrase refers to the length of the vessel doing the towing.

Memory Aids - you can move “ALONG” through this page too as its really pretty much the same as the two vessels (save for the lack of white on the vessel alongside!).
