In the UK there's not particularly stigma attached to it, but I would be careful to research the economics of it -- how much a month will you be paying to rent whatever mooring you have, how much (time and money) will upkeep and maintenance of the boat cost you, what's the initial expense of the boat and how much are you losing on a probably-depreciating asset, do you need to pay to dispose of sewerage, and so on... Do the cool things in life, but look carefully before you leap so you know what you're getting into and don't hit a brick wall of disillusionment.
