I would call this a traverse board. We have seen a few examples of this type of instrument on this list before. On a ship it would be used for dead reckoning, which has also been discussed on this board in the past. I am sure that there may be other names that this instrument would go by, so if I am wrong let me know.

As you can see on the picture, it represents the compass' rose, and in each direction, the branches of the rose are drilled by small holes, where wooden pins can fit. There is also (not really visible on the picture) another area where pins can fit, to represent the speed of the boat. 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 have a good idea of the dead reckoning, reading it like that: 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? Thanks in advance, - Olivier
