Why is it important to dry boats before moving to a different water body?

Drying boats before moving to a different water body is crucial primarily to avoid transporting Aquatic Invasive Species (AIS) to new locations. AIS can have devastating effects on local ecosystems, as they often outcompete native species for resources and can disrupt biological communities. When boats are moved from one body of water to another without being properly dried, they can carry microscopic organisms, plant fragments, or other invasive species that hitch a ride in the water that may be left in the boat, compartments, or on the hull. By ensuring that all equipment is dry, boaters protect ecosystems from the introduction of these harmful species, which is vital for maintaining biodiversity and the health of aquatic environments.

While reducing the weight of the boat or preventing rust and damage might have practical implications, these factors do not address the most critical environmental issue at hand. Similarly, maintaining the aesthetic appearance of the boat is less significant compared to the ecological impact of AIS. Preventing the spread of invasive species is the primary reason for the practice of drying boats before moving them, making it the most important consideration.
