We have a Liverpool Boat, 2007, there is nothing wrong with the hull. It looks to me as if the boat was lined by Liverpool Boats. We have a fixed double where there is currently a sofa bed, that could be changed quite easily with the benefit of invaluable storage space underneath.
The boat is being sold through Shire Cruisers, in my experience Nigel Stevens is an honest, respected and knowledgeable person so ring him and ask about the BSS. Could be a good boat at a very reasonable price, any work needed could be done over time. Do have a survey done tho.
