The chart refers to waves of 4-6 meters at Force 7, but again those

Not necessarily so.

Force 7 over open water for a day or two will produce the real thing
with lots of breaking crests, nothing "swell" about them. Mix in a
little adverse current at the same time and you could produce some
really steep 4 to 6 meter waves. This happens fairly frequently in
the gulf stream between Florida and the Bahamas, especially in the
winter months.
