Trice up, to

Or to ‘truss up’, can be used in much the same way as a farmwife talks of trussing up a chicken. You can trice up almost anything with cord or rope, but in practice this old term lives on mainly in gaff-rigged boats which have loose-footed mainsails. Such craft will have a tricing line attached to the Tack of the sail, running through a block at the Gaff jaws, and down to the deck. The tack of the sail can thus be hauled up to reduce the sail area and spoil its shape so that the boat moves slowly. The sail is then half-way to being Scandalised.
