I have also been very happy with my 1999 50ft Liverpool trad narrowboat. Owned the last 13 years and just re-painted the outside for the 2nd time. It was fitted out by the first owner and is a nice boat. Only mechanical replacement has been the PRM 80 gearbox with a new PRM 85. Beta 35 engine. Paid 25k for it and was immaculate. Updated the layout and systems myself over the years to include:
Walk through bathroom, Solid fuel woodwarm fireview stove with gravity rads, Webasto TTC. 3kw Victron inverter charger, Solar panels, Wood flooring, Added immersion to calorifier, NASA battery monitor, Trojan T105 Batteries, Split charge relay. Re fitted galley with separate under counter 12 volt fridge and freezer. Full size domestic Washer dryer. Slimline dishwasher.
Will get it blacked next year and see how the 8 anodes are doing after 4 years.
James.
