Thus, a "3-foot" wave is roughly six feet high (in actuality a height of ~1.8 m), i.e., head-high to a 6-foot (~180 cm) person; a "2-foot" wave is roughly four feet high (height of ~1.2 m), i.e., chest-high to such a person; and a "6- to 8-foot" wave would be 2 to approaching 3 times head-high to such a person (height of ~3.5 to 5 m).
