1) Sitting on blocks, covered by weeds in someones' side yard.
2) Advertised on craigslist as 'handyman special, make offer'.
3) Sitting up in the yard at the local marina. The marina owner is always trying to 'give' it to his buddies.
I don't think many really get scrapped, there is always someone with a twinkle in his eye who will save a boat, however awful the condition it's in. He may never fix it up but it's just the idea of it that keeps the boat alive.
I took my .73 hydrasport bass boat and hacked it into pieces with a sawZall and made a dump trip. Tank went to the anual fire dept collection. Sold the outboard and with some work the trailer is an great utility trailer.
I have read that Maryland has a tough law about abandoning boats...some jail time and a heavy fine if you are the last owner. But they also have a program that if you let the State know that you have a boat to dispose of, they will bring the equipment and the wrecking crew to a a boat ramp agreeable to all parties and cut up and dispose of the boat at no cost to the owner.
There was a lot full of FG boats in Laplata. After being there for several years, they cut them up and put them in a huge chipper. Something to do with insurance, so I heard. Was some nice boats in there.
I've been at the landfill on more than one occasion when someone trailered a boat in, backed up, and pushed it off. it was quickly cut up by the guys that work there. Funny thing was they looked better than some you see for sale.
