A ship-log records the distance travelled through the water. With the time in hours between the observations, it gives the ship’s speed in knots.

A very rare and complete yachting taffrail log. Hardly used. With clock, line, rotator, sinker weight and two shoes in a mahogany case. The log is fixed on a shoe at the stern of a ship. The recorder would have been connected with a line to the rotor at the end of the line. The governor wheel is fitted in an open end housing. The enamel face with two dials.
