I will be driving the Bulimba-Teneriffe ferry for the next week which has a reasonably challenging park on the inside of the pontoon. There is only a 20m gap between the terminal pontoon and an upstream jetty which, due to a back eddy during a flood tide and during the ebb tide, requires a reverse entry. Single engine monohulls don’t reverse in a straight line due to the torque of the propellor, so it requires you to “walk” the boat backwards and correct the direction every two boat lengths. I have done this shift about two dozen times now and it adds an interesting manoeuvring dimension each time.
