What is a recommended practice for managing safety on open motorboats?

Ensuring that all passengers are seated is a fundamental safety practice when operating open motorboats. When passengers remain seated, it significantly reduces the risk of falling overboard, which can occur due to the boat’s movement, especially in rough waters or sharp turns. Being seated also helps maintain the boat's balance and stability, which is crucial for safe navigation.

In contrast, driving at high speeds can increase the likelihood of accidents and makes it more challenging to give attention to the safety of passengers. Limiting the number of passengers might be necessary for weight distribution or capacity reasons, but does not inherently enhance safety as effectively as having passengers seated. Lastly, operating a boat without a lookout neglects an essential practice for awareness of other vessels and conditions, which is vital for avoiding collisions and ensuring a safe boating experience.
