I'm still trying to find a definitive answer on whether US ships in the Age of Sail rigged their running rigging on the mizzen mast like England or the rest of the world. I stumbled on this text while searching. I'll admit that 99% of this is over my head, but it's clearly a major resource for anyone interested in the 'technology of the era'.
