We moved to Tattenhall in April from the Bridgewater. We don't live aboard and our home is in north Cheshire. We looked at all the marinas in the locality and thought Tattenhall best. The marina itself is very nice if a little breezy(!)and the facilities are super. The staff are very professional and pleasant and have always gone out of their way to help us.
As far as location goes, it is probably less restrictive than Overwater; you have to go up the whole Audlem flight if you want to head south! Swanley is restricted by being on the Llangollen. We havn't found the double width locks a problem as we are not single handed. We have a car so access is not a problem and the local scenery is beautiful. We have not tried the bus services but are assured they are good, and the park and ride into Chester is minutes from the canal at Christelton and works very well. Tattenhall village is a bit of a hike but we did it in about 20 mins on foot and has a good variety of shops and eating and drinking places.
The fact that you are not cheek by jowl with other boats was a great attraction and you can select a mooring you like. Another plus, which clinched it for us, is that you get a free lift out if you pay a years mooring! We had our boat blacked at the workshop,they did the job inside because the weather was poor and made a good job of it. They welded on a new fender eye without asking or charging and told us where to get the matt black paint for the gunwhales at a sensible price! They are boaters, after all.
Altogether very satisfied.
