If the boat wasn't rigged for sailing when you bought it, you might want to rig everything in the driveway. You will probably find something missing, or confusing.
Sailing a small boat well (and safely) requires being able to respond quickly to situations without having to think about it too much. It is difficult to practice these things without actually going out on the water in the boat. But, the first step is to learn as much as possible before, and between each sail.
