Historical information
The line throwing apparatus has been in use for several centuries, in a wide variety of forms. It initially started off as manually launched lines that had shorter ranges and were not very accurate. They faced problems on wind-powered boats and ships since they were dependent on wind speed, wind direction, and the operator accuracy.
Significance
Modern-day line throwing apparatus are powered using rockets, pneumatic systems, or slingshot mechanisms. They fall under two main categories of propulsion- pyrotechnic, and pneumatic. Pyrotechnic systems make use of an ignition that is used to launch the line, whereas pneumatic systems make use of built-up pressure. Pyrotechnic systems are volatile and can be extremely dangerous due to accidental ignition. In response to growing concerns about the safety of pyrotechnic systems, pneumatic based launchers were invented and widely implemented in the late 20th century.
