Bridges: love them? or loathe them? Personally I love a good bridge, and I don’t only mean the type found on board ship either. One of my dreams was to photograph a ship going under a bridge, and that is a problem on it’s own because there are not too many navigable bridges in my area. The one exception is the Itchen Bridge
, which has a height of 28 metres.
(1500×576). The Itchen Bridge
I have seen a number of ships on the Itchen River and I expect there are a few limitations to taking a largeish vessel under the bridge without running into it. For maximum clearance you should go under at low tide, but then your vessel must not be heavily laden or you would run aground. You could go through at high tide too, but then you must be down on your marks, you also need to aim for the middle of the centre span. Oh, and it does not help if your vessel is higher than 28 metres.
I watched my handy vessel movements website for a number of weeks, trying to find a chance to catch a ship going under the bridge, and that came on the 20th of July when a dredger; Sand Harrier, was due to transit from American/Burnley Wharf to Southampton Water. I was due to go shipwatching at Weston that afternoon and hoped to be back in time to see this happen.
On my way to Weston I spotted the vessel alongside, and just hoped that I would be back in time, or that she did not sail early.
Shipwatching from Weston can be fun, but somedays there are certain ferries that are determined to ruin the photography. Once I was completed I headed up to the bridge. Sand Harrier had not passed me at Weston so she was still upriver, but anything could happen between my leaving where I was at Weston, and arriving on the bridge. By the time I got to the bridge she had not sailed, but by the looks of she was about ready to go.
It is not a long distance to sail, although you do have to be careful of small craft or the odd kayak that may be oblivious to what is bearing down on them. You also need to steer towards the centre span of the bridge almost immediately after clearing the channel. Interestingly enough the vessel is able to turn at the berth, and she does so without the help of a tug.
What a moment it was. The funnel gases and sound and sheer thrill of seeing something like this for the first time! I was so enthralled I forgot to press the shutter on the video camera. But, I did manage to get some video
of the event.
And then she was on her way towards Southampton Water, and I was on my way home. A happy puppy indeed. However, I needed to do this again. On 22 August I made an interesting discovery (which I should have noticed the first time around). Sand Harrier has a hinged mast! I feel cheated!!
Anyway, this is what she looks like from ground level. As you can see she is riding quite high, and the tide was out too, so she did not have a problem going under the bridge at all. I also managed to capture this sequence on video.
A further opportunity came a few days later when the dredger Arco Dee was due to transit from the same place and I was ready and waiting 30 minutes before sailing time.
The same circumstances were involved with relation to harbour traffic, tide, draft and weather.
And then she was past. This time around I did much better with the video
but did loose a bit as I had to cross the street and the traffic was hectic.
Satisfied? not really. I now needed to see this from the bottom of the bridge. As luck would have it the trailing suction dredger City of Chichester was due to transit. But the weather was gross, and the images were really not up to scratch, so I stuck around waiting for the next opportunity which happened on 15 August.
It was a late afternoon, same ship, but better weather. For some reason I shot mostly video, but do have a screen cap that will help.
It was difficult to know how much clearance there was between the tip of her mast and the bottom of the span, But by the looks of it there was quite a bit. The tide was high too.
And finally, the clincher.
As stated previously though, it really does depend on tide, draft, ship height and that you are in the centre of the span. I expect there may be leading marks out Weston Area or possibly at Hythe for guidance and I must check up next time I am there.
And that concluded three very interesting ship transits under the Itchen bridge. I now feel kind of lost, having completed my observations. The video is available on YouTube too, as are the video’s shot from above. Come to think of it, I haven’t managed to get this dredger from above yet……
