Which technique can be used to assist with horizontal movement in water?

Sculling is a technique used to assist with horizontal movement in water by using the hands to create propulsion while keeping the body relatively still in the water. This technique involves a back-and-forth hand motion, allowing an individual to navigate through the water without a full swim stroke. Sculling is particularly effective for maintaining a position on the surface or for making subtle adjustments in direction and speed.

While swimming, finning, and floating are all relevant activities in the water, they do not specifically highlight the technique of horizontal movement through water in the same manner as sculling. Swimming generally involves full-body strokes to propel oneself, finning typically refers to the use of fins with a more traditional swimming technique to enhance speed, and floating is primarily about maintaining buoyancy rather than significant movement. In contrast, sculling is about using specific hand motions to facilitate controlled movement, making it the most appropriate choice for this question.
