Douglas Sea Scale - The Scale

The Scale

The Douglas Sea Scale, also called the International Sea and Swell Scale, was devised in the 1920s by Captain H.P. Douglas, who later became Vice Admiral Sir Percy Douglas and Hydrographer of the Royal Navy. Its purpose is to estimate the roughness of the sea for navigation. The scale has two codes: one code is for estimating the sea state, the other code is for describing the swell of the sea.

Famous quotes containing the word scale:

    I own I never really warmed
    To the reformer or reformed.
    And yet conversion has its place
    Not halfway down the scale of grace.
    Robert Frost (1874–1963)

    There is something in us, somehow, that, in the most degraded condition, we snatch at a chance to deceive ourselves into a fancied superiority to others, whom we suppose lower in the scale than ourselves.
    Herman Melville (1819–1891)
