Hi I am new to boating and bought a 40 foot narrowboat a month ago. I had a survey done which showed it needed a few jobs such as blackening, new anodes, new rubbing strips. The boat was taken to a marina workshop to have the work done, I received a phone call Monday from the marina to say the work had been done and the boat went in the water Monday. I received another call this morning to say the boat had been found listing with a foot of water inside, I went to see the boat straight away and found the furnishings inside all waterlogged such as the bed, settee, carpets etc. I was told it was just one of them things and that the welder must have gone through a pitting underneath and not realised. The Marina said they will sort it out but what things do I have to look out for, any advice greatly appreciated.
