For Sale: Knot Log

[SkiprJohn]

Back in the "good ole" days before GPS we used to have to determine our speed and distance covered from one celestial sight to another and to do many calculations even while dead reckoning along the shoreline.

Here's the instrument we used to use for that purpose. It measures distance through the water by spinning the little propeller on a tether behind your boat. You too can become an "oldtimer."

$150 plus shipping please.

I'm interested John, as long as that ratty looking paper tells me how to use it and there's no requirement I actually do.

I'll PM you.

They work very well, and are pretty darn close to perfect and thats used against the GPS position in 24 hrs just my 2 cents Ive got one that worn out 2 props lol and if he don't buy it I will I don't need the instructions LOL

[Wotname]

Don't fight over it, I've got one that is available for sale if more than one CFer wants SkiprJohn's unit. Same as pictured. I had been thinking about posting it for sale but as yet never got around to it!

[SkiprJohn]

That ratty old piece of paper is the original instructions for the unit and tells you all you need to know but might fall apart whilst being read. Its got a lot of sea miles on it.
Got your email and will contact you soon.
kind regards,

A nice guy I met on another forum just sent me a KnotStick. I haven't used it yet but it gets great reviews. Knotstick Sailboat Speedometers

[SkiprJohn]

The knotstick is pretty good at measuring your speed for the moment. The knot log is for measuring distance. If you take your readings hourly then you can determine your speed. The knot log is for long distances and I had one going for 1500 miles very accurately read our distance for dead reckoning.
kind regards,

Knot log is sold. Thanks for looking.
