everything I know within 40Km of Warwick can be found at cresby.com > "Found Here" but just to get you started I have centred it on Warwick. Notably Banbury FC (Wed) is on the Oxford Canal less than 100 yards from it. Black Diamond (Fri) is in Brum but where you moor safely I cannot say, Gas street Basin is not too bad, a decent walk though.
The Gamecock in Tam'th (actually Polesworth) is fairly near the canal .8 mile according to Google, moor near Marker St bridge see Pub (Fri if I remember) but not sure if it still runs. But I suspect this is where they are now and they are also near the Coventry Canal.
With any of these it is best to check anyway.

Maybe see you at Warwick Folk Festival? You will spot me - say hello.
