The speed of sound waves in solids is faster than it is in gases.
Explanation:
The sound which is produce due to hitting of metal bar with a drumstick reaches to the ears in short time because sound is a longitudinal wave which requires or needs medium for its propagation from one place to another and in solids the particles of medium are close to each other as compared to air so the sound travels faster in solid materials as compared liquid and gases and takes less time to reach my ears.

In the situation given in the question, it is stated that manatees can not hear low-pitched sounds of the slow boats and therefore this could cause more collisions and deaths.
The answer that can cast doubt on the conclusion, if true, is that the hyacinth that the manatees feed on grows best in water that is still, so it would make sense for the boats the slow down even though the risk of a collision with a manatee increases.
I hope this answer helps.
