from
Bouvier's Law Dictionary, Revised 6th Ed (1856)
TOUCH AND STAY. These words are frequently introduced in policies of
insurance, giving the party insured the right to stop and stay at certain
designated points in the course of the voyage. A vessel which has the power
to touch and stay at a place in the course of the voyage, must confine
herself strictly to the terms of the liberty so given; for any attempt to
trade at such a port during such a stay, as by shipping or landing goods,
will amount to a species of deviation which will discharge the underwriters,
unless the ship have also liberty to trade, as well as to touch and stay at
such a place. 1 Marsh. Ins. 275; 1 Esp. R. 610; 5 Esp. R. 96.
