What is the purpose of Line 1?
Bow Line (when Mooring) Bra Line (when towing)
controls the vessels bow to the pier or alongside.
What is the purpose of Line 3?
Aft Spring (when Mooring) Backing Strap (when Tow)
When mooring this line can be used to take strain and open or close the vessels bow/quarter.
When towing alongside, this backing strap is the line that breaks the vessels momentum forward and tows the vessel aft when backing. opposing the tow strap.
