We moor on the CRT moorings on the Beeston cut. There are facilities though they are often out of use. It's a handy 15 minutes walk to the station. However, you'd be very lucky to get a 69 foot mooring, they're usually shorter.
We moored at crts bishop's meadow for a while but it's very noisy at the town end as its opposite a bus garage with maintenance and buses manoeuvring all night. There's water there but nothing else.
There's visitor moorings all along the roadside at beeston. Also visitor moorings at Sainsbury's, very handy for the town centre though can be noisy, or outside castle marina where the marina used to charge £5 a night, don't know what the arrangement is now but don't think able to use their facilities for that. It usually seems to be full there. There's also visitor moorings on the embankment in Nottingham, an easy bus journey into town.
Recently, on Facebook, someone advertised a mooring on the Trent by ladybay bridge, I don't have details but might be worth an ask.
