Yellow to port as you enter James Watt Dock

I can understand why it is not a red can buoy; that would confuse the main channel buoyage. It’s a difficult one, that’s why it’s yellow I suppose.
 
I’ve just moved there so the title caught my eye. I’ve only entered the Dock once and can’t say that I remember the yellow buoy. From memory, I think I followed the pilotage from the Almanac. Although someone had a bad day, thanks for posting to highlight Garvel reef.
 
Is not a yellow buoy defined as having 'no navigational significance'?

Ouch, Looks like a nice boat.

Not quite,
Its a Special Mark. It usually is significant. If not significant there would be no need for a buoy. A special mark is usually not directional Ie there is something special here. Go round it whichever way you like.

Occasionally a special mark is directional. Occasionally a special mark is also a lateral mark. One of the uses of a special mark. Can be to mark a deep water channel. In which case the Buoys are yellow but have a can or cone shape depending upon which lateral mark they are representing.

I am not familiar with James Watt Dock. Perhaps it could be replaced with a yellow lateral. Or a preferred channel mark if it may be confusing to users of the main channel.
If you think it should be changed.
Send in a report saying you had a near miss. Near grounding. Contributing factor. The purpose of Buoy was not clear.
The question to ask is whos in charge of the buoy? Clyde Ports or James Watt Dock?

Boats ground on this collapsed barrier often as JWD and Helensburgh lifeboat will attest. Two things might help. fixed beacons with cardinal top marks and an understanding of charts.
 
Do people not look at a chart or do a pilotage plan before entering an unfamiliar port? A glance at the chart and the big green area off to the north east of the yellow special purpose mark quickly gives its' function., and that certainly isn't to pass it on whatever side you like... JWD really isn't a difficult marina to enter or exit - just don't cut the corner!
 
I think if you're 'Polar Bound', mastering the complexities of entering James Watt Marina should be within your skill set. With or without a buoy of any colour.

I hope they ran aground around breakfast time, as I love having something interesting to look at outside the dining room window in the Premier Inn. Compensates for having to stay there sometimes.

“Often”? Frightening what sort of people are out there. One glance at a chart or plotter would easily avoid this.

I can't see why they could not use a small Southerly Cardinal. A Yellow buoy is so often just a racing buoy and must confuse.

I thought a cardinal was normal practice where two channels divide.

Yes. And I would have thought a West Cardinal would be a lot more helpful in that situation. Wonder what was the thought process, if any, leading to putting a plain yellow there.
And of course should always look at charts as well. But the whole point of painting buoys green and red, or using Cardinal markers, is to make things clear without having to remember or leap to a paper chart to remind the helmsman.
Plain yellow seems plain stupid for that location
 
Yellow buoy, west or south cardinal - any of them would require a quick glance at a chart to make sure what is ahead. I remember the 1st time I went into JWD, single-handed of course, and even I managed to check what was on the chart. Here's another yin that wasn't armoured against ice and sank in the middle of the harbour after refloating.
