Just so you know, any fiberglass FJ more than two or three years old isn't going to win races. Like International 14s, but much less so in the FJ, the hulls fatigue and lost their shape under stress. Also, unless the standing rigging was taken down after every race, the hull will creep and lost its shape.
That doesn't happen to wooden boats. That's why most world-beater Int.
14s were cold-molded, laminated plywood -- at least, until 2000 or so, when I stopped keeping up with sailboat racing.
None of this matters, of course, if you're going to be day sailing and not racing. But it seriously depreciates the value of those boats. You should get a good price if the boat is old, no matter what its apparent shape, because its racing days are over. And unlike an old race horse, you can't put it out to stud. d8-)
Bunker oil it a much longer chain molecule than ordinary diesel making it much more viscous so is heated to about 100c to thin it down to use in a ships diesel engine. The longer the molecule chain the more energy as it has as the ratio of carbon to hydrogen increases. The residue or stuff left over when all the flammable fuels are taken off is tar used for road making, there is virtually no waste from crude oil.
When I was involved with diesel converted, sulfur laden digester gas engines at a wastewater treatment plant in the 80's, bearings (to say the least) couldn't be replaced fast enough despite ridiculously frequent oil changes, although I've read that that issue is now purportedly to have been resolved:
The Euros were too busy killing each other off in an assortment of wars to even get past the early stages of syphilis. Hard to tell you have a disease if you die before it can affect your life.
Largely because they did not use slaves to the extent they did in the South US. It wasn't much of an economic deal after they could no longer sell slaves.
We used slaves in the West Indies. Sugar cane. Jamaica.
It was the war of Northern Aggression. They did away with slavery to ruin the economy of the South. Nothing altruistic. Lincoln wanted to repatriate them to Africa.
