Don't worry - the Severn's a pussy!
We're off down to Gloucester on Sunday, so keep an eye open for "Old Deuteronomy"!
They'll give you an information sheet at Upper Lode lock if you haven't done this bit of the river before.
As the lock is on restricted times, you may find that there is a queue. You need to call the lock keeper at preset (and well-signposted points) on the approaches to Gloucester, so he will be able to tell you about other traffic and whether it's likely you're going to have to wait.
The important thing is to remember to keep to the left and slow down as you come round the final corner on the approach to the lock. Ideally at this point you should see a pair of open lock gates and a green light!
Have a boathook and mooring line ready on the stern in case there's a queue and you need to pick up one of the chains that hang down the wall.
There is always a bit of current in this channel, so be prepared to reverse fairly hard to get alongside the wall if you need to. Moor up stern first. Do not use a center line!
When you're lining up to enter the lock, keep to the left, as the current tends to run left-to-right across the lock entrance.
Now the good bit. The channel down from Upper Parting into Gloucester is without doubt one of the most miserable bits of river that I know. It's in a deep muddy cutting with nothing of even the remotest interest in sight. If you are feeling depressed, don't go there! You don't really approach Gloucester, you sort of "sneak in" through the back door. Apart from passing under a few big road and railway bridges, you'd never know you were approaching a large city.
But it's all worthwhile just for the experience in Gloucester lock, when all the old warehouses are gradually revealed in their full glory as the boat rises in the lock. Somehow it always reminds me of way the old cinema organs used to appear, as if by magic. I never tire of it, and I hope you enjoy it as much as I do.
Have a good trip!
