We are part owners in a shared ownership boat and were based at Gayton 2 yrs ago. Marina staff very helpful with full facilities. Trips done by ourselves and other owners:
Leicester Ring
Birmingham
Stratford on Avon
The South Oxford
The Nene and Gt Ooze (2 weeks to get to Bedford, then do a remote changeover with another owner to return the boat)
Short cruises to Welford, Rugby
Length of time depends on how many hours a day you want to cruise
