Race to Dakar

Discussion in 'Racing, Motorsports, and Track Days' started by Takamii, Jul 5, 2010.

  1. I have been watching the race to Dakar with Charlie Borman

    being a layman in respect to these rally type events I was wondering if anyone could explian to me how they do the navigation ?

    They have that toilet roll of paper with instructions

    Do they have a counter on the bike then they move that roll manually in its special display case to do their navigation ?
  2. Yep, the toilet roll has distances on it, which is then compared with a odometer. The rolls are turned via push button & electric motor these days. (That's a very simplistic overview of how it works).

    You can still get manual rollers, matter of fact I'll be in the market for one soon, but not many riders use them these days.

    If you want more in-depth answers, check out the advrider forum.

  3. The 'roll of paper' route chart was allegedly invented by Denis Jenkinon who was Sir Stirling Moss' navigator in the 1955 Mille Miglia.....
  4. Actually the concept goes back much further - I've seen a Murray River Chart dated 1870. They were in common use by paddle steamers here and in the US.

    The one I'm familiar with was hand drawn on oilcloth and was about 300mm wide on a roll to leave space for lots of annotations (rivers change constantly).
  5. Leonardo Da Vinci invented them in 1501. Part of his work for the Medici family had him designing canals to provide trafficable waterways and drainage of swaps. He also proposed an invention that run two wheels on a rail on the edge of the canal that was either towed by a horse or could be dragged by the current He proposed mounting his longe mappa on the front of this invention so the driver could navigate effectively.
  6. That man just gets more amazing the more you know about him. Where did he find the time?
  7. you have to be so specific in this forum

    The 'roll of paper' route chart was allegedly invented FOR MOTORSPORT USE by Denis Jenkinon who was Sir Stirling Moss' navigator in the 1955 Mille Miglia.....

    happy now??

    Leonardo never drove in the Mille Miglia
