Why is a nautical mile different than a regular mile?
(Its length has varied considerably at different periods and in different localities; the legal mile is now 1,760 yards, or 5,280 feet.) Such a linear measurement cannot be used at sea, so the nautical mile is based on the length of one minute of arc (or 1/60 of a degree) of a great circle of Earth.

How do sailboats sail faster than the wind?
One force pushes the sailboat, and the other force pulls, or drags it forward. True wind always pushes a boat. If a boat sails absolutely perpendicular to true wind, so the sail is flat to the wind and being pushed from behind, then the boat can only go as fast as the wind—no faster.
