Drafting sites that should be given preference are those that:

Explanation:
Drafting from a water source works best when the pump and suction hose can be set up on stable, level ground that the apparatus can reach easily. A paved surface provides that stability, keeping the suction hose away from mud, debris, and soft ground that could cause hose kinks, air leaks, or loss of prime. It also allows the driver to position the pump securely and maintain the proper stance and hose angle for efficient priming and steady flow. Choosing a site that requires a long suction hose adds friction loss and increases the risk of air leaks and prime loss, making drafting less reliable. A site that demands a lot of lift forces water uphill, reducing pump efficiency and overall flow. And simply being away from bridges and boat ramps doesn’t inherently improve drafting performance and could introduce hazards or accessibility issues.
