Navigation Problems USCG Question #53 (Set 2)

If the pitch of the propeller is 19.4 feet, and the revolutions per day are 96,713, calculate the day's run allowing 6% positive slip.

Official USCG Answer & Rule Citation

Correct Answer: Option A — 290.1 miles

Multiply propeller pitch (19.4 ft) by total daily revolutions (96,713) and divide by 6076.1 to find theoretical distance. Apply 6% positive slip by multiplying by 1.06, resulting in a true day's run of 290.1 miles.
