⚓ Harbour Capstan: Rope Friction, Wraps and Holding a Ship with One Hand

A dockhand holds a mooring line wrapped round a bollard or capstan: the Euler-Eytelwein law T_load = T_hold·e^(μθ) sets how many wraps stop a wind- and current-loaded ship, with slip onset, stick-slip, frictional heating, rope creep, breaking load and a windlass with pawl.
