The sail-plan consists of elliptical sails made flat with bamboo inserts, permitting them to sail well on any point of sail. The junk is easy to sail, and reasonably fast. The rigging is very simple, because bamboo is very strong, and thus fewer ropes are needed. Classic junks were built of teak with multiple water-tight compartments, accessed by separate hatches and ladders. The largest junks were built for world exploration in the 1200s, and exceeded 150 meters in length.
Because junk cars are a source for scrap metal spare parts, they're often sold to a junk yard, where they are typically stacked (or strewn) about a large enclosure, sometimes guarded by a "junkyard dog".
Junk characters in electronic text can be caused by transmission errors (line noise) and often appear as groups of "strange" letters like punctuation or accented letters.
Junk is a song written by Paul McCartney which was featured in his first solo album McCartney.
