Water current has the most effect on what type of boat?

Water current has the most effect on smaller, lighter boats, such as canoes and kayaks. These vessels are more susceptible to being pushed off course by strong currents due to their lower weight and surface area. In contrast, larger and heavier boats, like cargo ships, are less affected as they have greater mass and momentum, allowing them to maintain course more effectively. Additionally, the design and hull shape of the boat can influence its sensitivity to water currents.
