Final answer:
To minimize environmental effects when launching a rescue boat from a ship, it is best to head the ship into the wind or current.
Step-by-step explanation:
When launching a rescue boat from a ship to minimize environmental effects, it is best to head the ship into the wind or current. This helps to reduce the impact of the ship's propulsion on the surrounding water and marine life. By heading into the wind or current, the ship's movement is counteracted, allowing for a safer and more controlled launch of the rescue boat.
