Nav Computer Bypass

Using the Nav-Computer Route Astrogation Bypass (N-CRAB) requires three astrogation rolls. The first is programming into the N-CRAB a duplicate of the original course (one difficulty level lower than the original course difficulty). The second roll is to chart a course from an upcoming point in the course to the new destination (the difficulty can vary dramatically, from Very Easy to Heroic). The final roll is to properly feed the course through the N- CRAB into the nav computer (this roll is one difficulty level lower than the second roll). Missing the first or second roll simply means that the N-CRAB will not function. Failing the third roll by any amount causes a mishap as described in the Rulebook. The whole programming procedure takes one-tenth the time of the new hyperspace travel route. Unfortunately, the N-CRAB has a tendency to interfere with a ship's nav computer. The nav computer must be "cleaned" via programming (a Moderate astrogation or computer programming/repair roll). For a second use of the N-CRAB without cleaning, all astrogation difficulties are one difficulty higher. For the third use, all difficulties are two levels higher. Additional uses incur higher penalties (difficulties above Heroic are rated as Heroic+10, Heroic+20, Heroic+30 and do forth).
