A paddle is used for steering a boat, while an oar is used for propelling it.
An oar is longer and used for rowing a boat by pushing against the water, while a paddle is shorter and used for kayaking or canoeing by pulling through the water.
The shaft of an oar is the long, straight section that connects the blade to the handle. It is designed to provide leverage and control while rowing, allowing the rower to effectively propel the boat forward.
