Yes, it's highly likely; otherwise, some of us wouldn't have cars, boats, houses, or much else. House prices, exorbitant mooring and licence fees, the boat safety plan, and insurance costs make it harder than it has ever been, but if you never, ever pay money for anything that you can do yourself and spend time locating every last nut and bolt, you can accomplish a great deal. Believe it or not, when I first moved onto a boat, I used to find enormous lumps of poor quality rocky coal sitting at the bottom of railway embankments, too massive to move. Skips frequently have nice lumber, and auto spares abound in breakers yards.
