We have two bollards for you and both happen to be predominately black in colour with a white top. If we take a look the picture (above) we can see a relatively modern looking bollard cylindrical in shape together with three ridges and the traditional domed shaped top.
If we look at the bollard (below) you'll notice it is chunkier in shape and we see can see the ridged area working for it stops a rope from slipping upwards and off the bollard. A very good way to secure a boat to a dockside with a decent piece of rope in my opinion. The bollard has a much larger body/circumference and it tapers inwards until it reaches the more pronounced ridge. After the ridge we see the body taper outwards and it's capped off nicely with a white coloured domed surface that carries the words 'St Katherine Docks' complete with crest/emblem.

We have found that some or should I say a few bollards in London were actual cannons and some of these cannons may well have found themselves aboard fighting ships of their day however there is another nautical link with the word bollard and this is to do with Tug Boats and the measurement of their torque or should I say pulling power.
Please do take a look at the Professional Mariner or do a quick search of the term 'bollard pull' and like me you might be a little surprised.
