  • Water craft leash
    Patent number: 9067654
    Abstract: A leash for a recreational water craft has a body attachment section and a rope. The rope has a more elastic rope section and a less elastic rope section connected end to end. The more elastic and less elastic rope sections are tethered through outer ends to the body attachment section. The less elastic rope section is longer than the more elastic rope section in a non-stretched state and is tethered to the craft in use through a craft rope sliding element. The less elastic rope section has a blocking element preventing passage through the craft rope sliding element. When the body attachment section is pulled away from the craft, the more elastic rope section expands, allowing the less elastic rope section to slip through the craft rope sliding element.
