Thank you for all the information.
I have looked into the other costs repair + survey + insurance etc. The boat prices are little grey zone to us, as we are not sure how much we could buy for boat. We know that most used boats need something to maintain obviously, however, we are ready for the challenge.
I have also noticed that some of the cruisers don't have a shower... ( who needs that anyway)
We have savings plus the loan we are trying to get at the moment, we are hoping up to 80k. It is very difficult to say, at the moment taking consideration of the current situation, and and even if I would look online for tips, I would not have the same experience to say what is good what is not really. - We learn from the hard way?
I have also looked into to new boat possibility, but I have not to look into the prices for new boats other than narrowboats.
