sea-rate

The Sailor's Word-Book

The going of a chronometer as established on board, instead of that supplied from the shore. This may be done by lunars. From motion and other causes their rates after embarkation are frequently useless, and rates for their new ever-changing position are indispensable. This rate is sometimes loosely deduced between two ports; but as the meridian distances are never satisfactorily known, even as to the spots of observation, they cannot be relied on but as comparative.
