Imagine you are walking up the stairs. Instead of stepping up, a door closes in front and behind you and raises you up to the height of the first step. The front door opens and you walk onto the step. Then it happens again, doors close and raise up to the height of the second step.
With a boat, they float into an area and get boxed in. The box is filled with water which makes the boat rise to the level of the next “step”. They then drive out at that level.
