According to the "Oxford Companion to Ships and the Sea" the definition is...
"Rope -- the name given in the maritime world to all cordage of over 2.5 centimeters (1 in.) in diameter, whether made from natural, or manmade, fibres, or wire. ..."

PS There were no listings under "Rope" specifying particular uses. Likely, the listing(s) would be under the word preceeding "Rope" in a multi-word name.
