Which factor affects coasting distance when stopping the boat?

The factor that affects coasting distance when stopping the boat is the weight of the boat. A heavier boat will require a longer distance to come to a stop compared to a lighter boat due to increased momentum. When a vessel is in motion, its weight plays a critical role in how quickly it can decelerate. Heavier boats have more inertia, which makes it necessary to apply more force to slow them down effectively. This means that even if the engine power is cut, the momentum will carry the boat further, increasing the stopping distance.

Other factors such as the direction of wind, size, and type of water can influence handling and maneuverability, but they do not directly affect the basic principles of inertia and momentum in the same way. For example, while wind might create resistance or assist in moving the boat, it doesn't fundamentally change how weight influences stopping distance. Therefore, the weight of the boat is the primary determinant when it comes to coasting distance.
