If so, any thoughts/recommendations?
No, but thanks for pointing them out. They are bound to wind up in my library (does anyone, besides me still have a room dedicated to books in their house?). The numbers I have been slinging around are absolutes. Of course a one knot wind will not propel a ship at one knot. There is a whole science devoted to sail efficiency. square rigged sails are at their most efficient (and more efficient than any other rig) when running before the wind. Bermuda rigged ships are more efficient tacking and jibing into the wind. But in the golden age of sail, all square rigged ships pretty much had the same sail efficiency, so, in a game like SOG, it's OK to ignore it. A Chinese junk could sail much closer to the wind than other square rigged vessels, which made them great pirate ships.
