They differ so much because you don't have the whole story. And you're not alone, so to bastardize a line from Paul Harvey, "And here's the rest of the story..."
Yes, Bob sold the boat exactly the way I described. The buyer was a very rich man who had made his fortune with a fleet of Alaskan King Crab fishing boats. When he bought the boat, he was very excited. He even told Bob and Jody that whatever they didn't want to take off the boat (placemats from Tonga, plates from Greece, etc.) he would love to have as he was going to start cruising right away.
The Lost Soul has a 160hp 6 cyl engine (can't remember what kind, either a Ford Lehman or a Perkins). During the test sail, Bob explained to the guy that they cruised under power at about 1,500 rpm. He added that they ran the engine up to 1,800 rpm for short periods, but no more than that. When they buyer went on his first trip, he told his hired Captain that he knew "these engines and they cruise at 2,000 rpm". So he instructed the captain to do so, and they ran it for 6 or 8 hours at that speed. Not exactly sure what happened, but the engine overheated and "broke". So the guy had it completely rebuilt. Nice to have lots of money, eh? They took it out again, and he told the captain to take her up to 2,000 rpm again. After many hours, it "broke" again. He called Bob and said he was fed up with sailing and would sell the boat. And this all took place in about 45 days or so. This really peeved Jody, as they left a bunch of the aforementioned cruising items, simply because the guy was so enthusiastic about cruising aboard the Lost Soul, and they liked him. Needless to say, both Bob and Jody are disappointed in the way things went.
They really thought they were giving the Lost Soul a good new owner who would care for her and cruise her around the world for years.
I don't know if Bob is helping him sell the boat or not, but the "for sale" ad you see in the magazine is for the current owner, not Bob and Jody.
And now you know, "the rest of the story..."
