A line launcher for launching a line spool provided with a length of line thereon toward a devised target comprising: a projectile or propelling means, generally a blank cartridge chamberable into a conventional marine flare pistol; a tubular housing with the line spool container therein; a lead ballasted end cap; a bored fore end cap; and an air spaced within the housing. One end of the line projects from the housing through the bored end cap and may be secure to a heavier line. Upon launching the device by discharge of the pistol, the line continuously uncoils from the line spool until it reaches the point of impact. A secure line is then provided between the point of impact and the securing point.
