double, to

The Sailor's Word-Book

To cover a ship with an extra planking, usually of 4 inches, either internally or externally, when through age or otherwise she has become loosened; the process strengthens her without driving out the former fastenings. Doubling, however, is a term applied only where the plank thus used is not less than 2 inches thick.


To double a cape. (See doubling a cape.)
