No it does not. The tide will be with you.

To be clear Kaedby lock can presently allow narrowboats to exit onto the Trent at close to high water (subject to sufficiently high tides) for a passage upstream on the Trent. Boats can enter Keadby lock at close to high water (also subject to sufficiently high tides) although arriving at high tide on the Trent is not likely to be considered feasible for a narrowboat travelling North on the River Trent. Narrowboats are able to travel upstream on the Trent out of Keadby and wait at the pontoon at Gainsborough for the next tide to carry them further upstream.

The Vazon bridge is the rail bridge . But the nearby road bridge is called Vazons bridge

Lumpy water boats may go on inland waterways so need insurance They may go in marinas that require insurance It is wise to have third party cover as a minimum even where insurance is not mandatory If accidental damage or total loss occurs the loss may be financially significant. As an example boats have been known to hit submerged objects and the costs involved in repairs can be significant.

A friend just had to have a survey on his salty water motorboat . Apparently it was a 25 year requirement. But he has owned the boat since 2014 and did not have a survey at that time. Another friend has not needed a survey for insurers on his 1998 boat but he did have it surveyed when he bought the boat about 3 years ago.

Thank you for the explanation.

Another line of enquiry might be to ask the surveyor who issued the existing certificate. Although the OP may not have that information if he bought the boat with its current valid BSS. I felt sure the last three (at least ) BSS certificates I have had have been pdf only sent by email . A quick search suggest the certificates became pdf in 2013. But I always print up a copy and I have a file on the boat for that sort of thing.

I suggest contacting C&RT with your certificate number which you can see from your C&RT account for the boat , and perhaps they will be able to send you an email with the certificate attached.

I would say it is not taking on water at present but it is possible the bow has been below the water a some point when river levels were higher .

Back to fenders - some of the lock sides can be abrasive concrete And the water flow quite turbulent . Going upstream the locks on the Trent (below Nottingham) are not such a gentle ride compared to most on the canals.

The great majority of all C&RT toilets are now closed to use by boaters etc in the sense that locks have been changed . This was announced last year and the closures started in November 2025. https://canalrivertrust.org.uk/boating/go-boating/boat-facilities-and-services/closed-facilities

The boat has been there many months and it seems the winter high water levels have left it grounded.

I have noticed the general absence of fenders on most narrowboats other than the rope type on the stern and bow . Some of the walls of the locks on the Trent are sheet piled and others are rough / abrasive concrete which must be quite good at paint removal. Most of the locks are quite turbulent when going up. Something to cushion the boat from impact and abrasion on the lock walls would seem to me a sensible precaution but of course it is not mandatory. At moorings you will have boats passing and making some wake so again the use of fenders is not a bad idea but not mandatory.

In the time available probably best to buy the chart from Newark marina . But they are available mail order , https://theboatingassociation.co.uk/product-category/charts/ Nothing to be nervous about if you follow the chart
