- it is the sudden release of static energy stored in the stretched line when it breaks. the end of the line snapback, striking anything in their path w/ tremendous force
the entire area of mooring decks should be considered a snapback zone.
general principle of line
very short lengths
- breastline athwartship restraint
- spriings longitudinal restraint
- very short lengths should be avoided as possible bec. such line will take a greater proportion of the total load when movement of the ship occurs
