Hello all,
thank you for the enthusiastic reply's to this question. It is really a pleasure to see to many like minded people enjoying this lifestyle as much as I do!
My family and I are liveaboards, based on the Avon in Stratford-Upon-Avon. We are looking at building and fitting out a new boat (we did the same with this one, it was a huge amount of fun, so much so that I want to do it again), and have subsequently put our boat up for sale. We have accepted an offer from a gentlemen wanting to take the boat to London, hence my question.
Having live in Stratford, we have cruised the Avon when time allowed. It is a big boat, but navigation is just about possible. As others have mentioned the locks at Evesham and Chadbury, are the only really difficult ones. Evesham is actually shorter, however it has a triangle cut out of the cill, to stick your rudder or bow in. Chadbury lock does not have this. We require a bit of rain to bring the river level up to get through. Obviously not ideal but for us it has not mattered much due to our particular life style. For us the boat is 99% house.
For reference the locks do vary dramatically on the Avon, the Upper Avon locks are generally much larger, some of them having been completely rebuilt, compared to the Lower Avon locks which were restored. Seems a bit odd as Stratford is the navigation limit for widebeams. The Rober Aickman Lock in Harvington is indeed the largest, by a long way, I heard a roumer that during the restoration a pair of hotel widebeams wanted to cruise that stretch and managed to wangle the building of a double widebeam lock to help there operation, I don't know the truth of this though?
Going to back to my original question; We have not yet taken the boat past the Avon, and if this sale is to go through, then the new owner would be looking at saving on the transport costs and making the journey to the Regent Canal via water as previously explained., So to conclude, this shouldn't be a problem?
