Gloucester Harbour

It is strange to find a harbour so far from the sea, but then you really need to remember that the Severn is not a small river. Gloucester harbour is not a deep water port as I know it, but was built more as a harbour for barge and small vessel traffic. Unfortunately, like so many of these places the need for it became superfluous as the truck and better roads brought about a whole new way of moving goods from one place to another.  Even the railways were not immune to this new way, and Gloucester, like Tewkesbury and Cheltenham were all in the firing line of the Beeching axe

Today the harbour is a small boat and pleasure craft harbour, with a lot of narrow boats and yachts and small pleasure craft (aka floating gin palaces). However, the buildings remain, being converted into yuppie pads and trendy working areas or shops for those that are attracted to them.

Use the image above to get an idea of what this area looks like and realistically the easiest way to see the harbour is to use our fictional vessel: “Diverse Alarums” and start from where the River Severn splits and the left fork is the entrance to the locks that will enable us to enter the “Main Basin”

Do not be tempted to go to starboard because there be dragons. Seriously though, that part of the river may not be very navigable, as I saw trees drifting downstream along it. 

The lock also has a lifting vehicle bridge over it, as well as an associated control cabin. The road would take you to the back of the warehouses on the right bank of the Main Basin. I did not really explore that area too well though.

Assuming we were successful, the Diverse Alarums would exit into the “Main Basin” which has a number of interesting things in it.  The image of the basin below is looking towards the lock which would be in the top left hand corner.

Sailing down the basin, roughly midway there is a cut that is the entrance to the Victoria Dock. It is really just pleasure craft that are berthed there and is of no real interest to somebody like me who prefers working vessels. 

Going full astern to escape the the throng of very expensive craft we are safely back in the main basin. On the right hand side of the basin are two drydocks, and these are really fascinating places for somebody like me. I did a blog post about drydocks many moons ago and these two feature in that post. Today both docks were in use.

Just past the drydocks is what is known as the “Barge Arm”. It is occupied by a bucket dredger with the rather quaint name “SND no 4”

The building in the shot is home to the National Waterways Museum. I visited it in 2015 but I was not impressed. It seemed more geared towards young visitors instead of jaded oldies like myself. 

If we go astern again and turn back into the basin we will be presented by the Llanthony Bridge which is a lifting bridge. It is the third bridge at this site and was built in 1972. 

Exiting from this bridge the quay to our Starboard side is known as the Llanthony Quay and it was built in the early 1850s by the Gloucester & Dean Forest Railway Co., soon taken over by the GWR, to provide a means of supplying coal from the Forest of Dean as an export cargo.

Baker’s Quay would be on the port side and was constructed in the late 1830s by a group of local businessmen led by Samuel Baker at a time when the Canal Co. was heavily in debt and could not finance much needed additional quay-space.

The red vessel in the distance is the former Spurn Head lightship that used to be moored at the mouth of the Humber Estuary. She was decommissioned in 1985, she has served as the headquarters of a yacht club and as a tourist attraction in various locations. She was extensively restored and converted into a treatment centre for alternative medicine under the name “Sula” and at the moment she is up for sale. If only I had vast amounts of money….

The area opposite her on Baker’s Quay is not accessible and recently a warehouse burnt down there. There is some serious foliage on the one building, 

I did walk into this area but there was not much to see except for the sort of space that would make any urbex buff smile knowingly.

If we had continued along past the Sula and the old warehouse buildings we would be facing the High Orchard Bridge. I have not gone much further than the lightship though. Maybe another day? I did see a sign for a Telford Bridge so need to do some investigating of that. 

It is  bascule bridge but I have not seen it raised yet. Beyond that I have no idea. At one point I will go on a boat trip downriver and see how far it gets us. There is quite a lot of interesting stuff down river but at this point we will disembark from our well found tub because our tour around the harbour is complete. The Gloucesterdocks website covers most of this in much better detail than I can and is well worth the visit.

Ships and small craft.

There are not too many vessels that catch my eye here, but some are worth showing.

This beauty is called Johanna Lucretia, she is a topsail schooner and was built in 1945 in Belgium.

Severn Progress  is a tug and was built in 1931 by Charles Hill & Sons Ltd, Bristol. Her low profile is necessary to sail under low bridges.

Dry docked.

While rooting around amongst my pics I remembered that I had some interesting ones that I took in Gloucester in August 2015. I was hoping to get back to the city at some point, but then other things intervened and I never did (since rectified).
 
This post is about dry docks and ships, and it is really a series of images that I took way back in the 1980’s when we were in Durban and got the chance to go down into the Prince Edward Graving Dock. There were two vessels in the dock on that day and it was quite a thrill to walk underneath those tons of steel. The ships were Mobil Refiner (top image) and Regina D (lower image)

For those that are interested in these things, the principal dimensions of the dock are:

Overall docking length 352,04 m Length on keel blocks 327,66 m
Length on bottom 352,04 m Width at entrance top 33,52 m
Width at coping 42,21 m Inner Dock 138,68 m
Outer Dock 206,90 m Depth on Entrance MHWS 12,56 m
Depth on inner sill MHWS 13,17 m    
You really get a sense of scale when you get to see how big ships actually are, and these two were relatively small vessels compared to what is floating around nowadays.
 
Unfortunately my images are not great,  The problem with taking pics down there is that there are patches of deep shadow and patches of bright daylight which really messed with the camera (and operator). Then the conversion process from slide to jpg further degraded the images. But, it is a great memory.

Cape Town has the Sturrock and Robinson Dry dock, and Clinton Hattingh was kind enough to send me these images of the latter showing the keel blocks 

The Robinson Dry dock is the oldest operating dry dock of its kind in the world and dates back to 1882. The foundation stone for the dock was laid by Prince Alfred, second son of Queen Victoria.

Now wind forward to August 2015 and to Gloucester where there were two dry docks, and one was occupied by a sailing ship.

I don’t think that caisson has been opened in many years, although in 2017 I revisited Gloucester Harbour and that dock was occupied. 

The vessel is the Den Store Bjorn, built n 1902.

Of course there are a number of these drydocks around in the the UK, The most famous one in Southampton is the King George V,  and it was the place where the really big liners were overhauled. Many images exist of the dock with one of the Queens in it but sadly the caissons have been demolished and the dock is now used as a wet dock. What a waste!

Southampton also used to have the Trafalgar dry dock which is close to the Ocean Terminal, it too was used by many of the famous liners, including a number of Union-Castle ships. It has been cut in half and the one half has been filled in while the other is a rectangular pool of water.

These facilities were built for the ship repair industry that the city once had, but that trade has moved offshore to Europe and today these spaces are only really known to those who have an interest in ships of the past.

There are two other dry docks of interest in Portsmouth, both inhabited by famous ships.

The first is the dock where the Monitor M33 is on display.

and the drydock where HMS Victory has been for so many years.

And finally, there are two more dry docks that I would like to mention, both with preserved vessels in them. The first houses the Cutty Sark in Greenwich.

and the other houses the SS Great Britain in Bristol.

Both of these provide an interesting glimpse at the underside of ships, as well as the opportunity to marvel at their construction and how large they really are. 

When this post started out originally it was only really about the Durban trip, but it has grown into much more as I have experienced other similar docks, and what a fascinating journey it turned out to be.
