noun
jib
JIB/dʒɪb/
A triangular sail set forward of a mast.
The jib fills with wind as the boat turns.

Etymology
The projecting crane arm borrows the nautical name. The sail-name's deeper origin is uncertain, but that does not separate these later uses.
In context
the shivered remnants of the jib and fore and main- top-sails were cut adrift from the spars
