Knot Log Clock is replicating a vintage 1930s taffrail log used by mariners to determine vessel speed while at sea. Pendulux has faithfully repurposed the taffrail log in solid cast and machined brass and aluminum. Fitted to an adjustable stanchion on a round wooden base, the time can be displayed at almost any latitude or longitude. The vintage dial is true to the original, which accurately conveyed knots per hour for safe navigation.
