> In French, it's called "renard", that means "fox" in English.

> There is also (not really visible on the picture) another area where

> It was used as follow. The driver had an hourglass beside him, and
> everytime it was empty, it was to be turned upside down, a pin was added
> in the direction that had been followed during the previous watch, and
> another one to describe the speed the boat had during that watch.
> Than, after some time, the navigator came by the "renard", and could

>
>  From 00:00 to 04:00, traveled at 6 knots in the NNW.
>  From 04:00 to 08:00, traveled a 6.5 knots in the NW,
> etc

> Would anyone know how this instrumnet is called in English?
