Tutorials/Water ladder

The "Water Ladder" is a structure to facilitate quick climbing in a strictly vertical manner. The accessible portion of this structure is a 1x1 shaft, but if created above ground would require 3x3 blocks of horizontal space.

The Ladder is essentially two shafts separated by a wall. At the top of the second shaft, a water source block is placed. The ladders are placed, much as they usually would be, every other block. However the placement here is important; the first ladder must be placed in front of the hole leading to the water source block.

For every two blocks dug down, dig two blocks over and then one up to connect the water shaft. Place ladders in front of all of these openings to stop the water from flowing out into the ladder shaft.

When completed, the water permits the user to climb faster than if just climbing ladders. It has been noted that this phenomenon can be achieved by placing signs in front of the water outlets as well, but if the water ever is stopped, you can't climb signs back out.

Another reason to use ladders rather than signs is resource effeciency. It costs 7 sticks to make one ladder, equal to 3.5 planks, while a sign is comprised of 6.5 planks. Ladders also stack in your inventory, so you can carry more of them, or have room for other gear.

There are a couple videos on YouTube featuring the speed of a water ladder and also the creation of one.
