In total contrast to Lincoln, which has minimal facilities for visiting boaters, Nottingham has excellent moorings. As well as those on the Trent, near Trent Bridge, there is an almost unbroken line of mooring possibilities stretching from the city centre for over a mile to Castle Marina on the Nottingham Canal. Boaters have a choice of tying up within metres of the railway station and shopping centre at Carrington Street bridge or, if this is too noisy (and the presence of a number of large canalside pubs and clubs suggests that it might be, at least at weekends),you can find somewhere quieter near Castle Marina.
These moorings really do have (almost) everything. A pleasant tree-lined location; mooring rings or bollards to tie to; a busy towpath with plenty of passers-by but no loiterers to give that all-important feeling of security; two pubs (one with toilets accessible without going anywhere near the bar - always a consideration for boaters!); a supermarket (with more toilets!); deep water, which means that when boats do pass at speed (and they do!) you are not disturbed and a short and pleasant walk along the towpath - or a quick ride on the frequent 13/14 bus - to the city centre. Best of all, apart from a very short stretch of 48hr mooring the maximum stay allowed is 14 days.
The one thing they don't have is access to water or elsan disposal, but at least that keeps the local "continuous moorers" away!
On my way down to Boston in June I paid nearly £150 to leave Starcross in Castle Marina for seventeen nights (with a discount on the nightly rate of £10.50). I have no complaints, but having now seen the moorings on the towpath outside I'd have been just as happy to leave her there free of charge (and moving on three days earlier, obviously!).
