He would never be sailing at that speed. Perhaps motoring, never sailing.

How many feet/second is a boat moving at 6 knots?
About 9. (1.5 feet/sec per knot.)

So, if I'm sailing 18 feet/second, I'm doing 12 knots?

Well, given the correction that 6 knots is nearer to 10 feet/sec, if you
were doing 20 feet/sec, then that would we 12 knots.
