In this one, you can get new random trip times by hitting the "New Boats" button.
To change the times of the boats go to the input bar and enter your desired time for each boat. For example, if you want the times to be 3 hours and 4 hours enter TA=3, and hit enter, then type in TB=4 and hit enter. Note this is the time to cross [i]one-way[/i].
