Bij dit geautomatiseerd mechanische log stond de teller op de achtersteven van het schip terwijl de spiraal in het water kon draaien. Nu moest men het toestel niet meer uit het water halen om het af te lezen.

This log was used to record a ship's speed. This device would have a line and 'fish' or spinner attached to the rear. The spinner was then cast into the sea, and as it turned in the ship's wake, the revolutions were counted by the mechanical log to record the distance travelled and the speed.
This type was also used on the trainingship Mercator.
