You are on course 079°T, speed 11.2 knots. At 0904 you see a daymark bearing 078°T at a range of 4.6. If you change course at 0910 to leave the daymark abeam to starboard at 0.5 mile, at what time will the daymark be abeam?

Correct Answer: Option B — 0928

Using standard USCG piloting and running fix techniques, compute the vessel's run during the interval before the course change at 0910. Projecting the remaining track to achieve the 0.5 mile abeam clearance establishes the correct arrival time at 0928.
