At the near end of the Speccy Tour 2005 mike_myers uploaded a recording for this game including a bug that we had to DQ in the Tour, and here at Regulation Play.
The bug is that if you do a bad crossing, and your money gets into minus, then it goes below 0 and award you around 100.000 points. This is not allowed. Should you make a crossing/sailing where you go in minus (non-profit), then the game is over, and your final score is the score you had after the previous successful sailing. To see a recording with that bug, visit our Disallowed Bugs page.
