I use my boat as a second home during the week as I work 80 miles or so from where my house is. Attempting to sell the house currently, which will change this arrangement and I'll live at home permanently, but I'll keep the boat if I can - we holiday on it every year (great holiday if you have dogs - dont like sending them to kennels), and its a great place to chill and get away from the rat race. Cost is about 3k/yr for licence and mooring, and maybe another 500 or so for maintenance (blacking, paining, fixing whatever breaks etc). Prices have indeed soared in the past few years.
Little update on the boat HiFi - swapped the 92 for a 102 I picked up from a fellow fishie a few weeks back, and now have a decent DAC I picked up locally - a SMSL DO100 - lots more detail than the £9 apple dongle I was using (although the apple dongle has a more solid low end - perhaps need to try a different USB cable as its just a free one that came with an external SSD I'm using). The 102 will eventually meet a 140 and hicap to replace the Nait 3 at home, and the arcams will be a bedroom system if and whenever we move house. In the meantime, I'm gonna enjoy this cluttered but great sounding lounge on the boat! The home set-up suffers from background noise, as our house is on the high street... here, it is pretty silent - just an occasional tweet from a bird. So the dark quiet bits are really black. Gonna need to buy a house in the middle of nowhere - love this extra drama that I hadnt realised road noise was removing!
