Trunk Deck Ship

A trunk deck ship is a type of merchant ship with a hull that was stepped inward in order to obtain more favourable treatment under canal toll rules then in effect. As those tolls were set by net tonnage, a measure of volume, and as the tonnage rules did not account for all of the cargo space of such vessels, they incurred lower tolls than more conventional ships of equivalent capacity. When the measurement rules were changed, the type was no longer built.

Famous quotes containing the words trunk, deck and/or ship:

    through the Sumner Tunnel,
    trunk by trunk through its sulphurous walls,
    tile by tile like a men’s urinal,
    slipping through
    like somebody else’s package.
    Anne Sexton (1928–1974)

    Positively I sit here, and look at Europe sink, first one deck disappearing, then another, and the whole ship slowly plunging bow-down into the abyss; until the nightmare gets to be howling. The Roman Empire was a trifle to it.
    Henry Brooks Adams (1838–1918)

    The ship goes on
    as though nothing else were happening.
    Generation after generation,
    I go her way.
    Anne Sexton (1928–1974)
