Final answer:
Before launching into Maryland waters, your trailer should be located in a designated preparation area where you can clean and inspect your vessel and equipment to prevent environmental contamination.
Step-by-step explanation:
The location of your trailer while preparing to launch your vessel is important for ensuring both safety and environmental protection. To prevent the spread of invasive species and pollutants, it is important to take certain actions before launching into Maryland waters. These actions include removing all visible plants, animals, mud, and debris from the boat hull, propeller, anchor, and trailer; draining and rinsing live wells, bilge areas, and coolers; and rinsing all fishing equipment, boats, trailers, and SCUBA gear with a hard spray from a garden hose. This preparation should be done in a designated area, away from the water, to avoid contaminating the ecosystem.
