Abstract
Abstract A yieldable mooring line for a boat comprises a coil spring with first and second spring key clevises connected to opposite ends of the spring and projecting therefrom. A chain at one end is connected to the first spring clevis. A line is removably anchored to the boat, and a snap-on is secured upon one end of the line which is removably connected to the other end of the chain. The second spring clevis is adapted for connection to a dock or piling.

Total Claims: 17
Claim 1
Independent Claim
212 words
A yieldable mooring arrangement for a boat comprising a coiled spring having a longitudinal axis; a boat; a first and second spring key clevis connected to opposite ends of said spring upon said axis and projecting therefrom; a chain at one end connected only to the first clevis; a line removably anchored to said boat; a snap-on secured upon one end of said line and removably connected only to the other end of said chain; said second spring key clevis connected to a dock or piling; each of said first and second spring, key clevises being swively retained upon said axis within the respective ends of said spring and rotatable relative to said spring thus allowing relative rotation between said dock or piling, said spring and said chain; each of said spring key clevises being of general S-shape with the extreme ends of the S-shape being bent inwardly to almost contact the body of the S-shape resulting in an 8-shape having two loop ends, with one said loop end thereof projected into and retained within the end of said spring; and the coil ends of said spring being of decreasing diameter forming a throated opening at opposite ends of said spring; said one looped end being oversized relative to said throated opening.
