Answer:
Turner is relieved the beach is empty; he hates being watched by the townspeople because he is the preacher's son.
Step-by-step explanation:
The fact that Turner was the son of preacher does not afford him so much freedom as he does not like to be watched by the people. This could be seen from the excerpt, where it is said that, if Turner saw just one person on shore, he would light out, This shows that Turner enjoys freedom, but he was living a restrained lifestyle due to his father's status.
