We can use the formula distance = rate x time. Let t be the time in hours. Then the distance travelled by the first boat is 7t and the distance travelled by the second boat is 6t. The total distance between them is 7t + 6t = 13t. We want this distance to be 52 miles, so:

13t = 52
t = 4

Therefore, they will be 52 miles apart in 4 hours. The correct answer is choice C.
