68. Visibility becomes variable in patchy fog and you maintain 5 knots speed. At 0610 you sight Montauk Point Light bearing 239°pgc. At 0630 you sight Watch Hill Point Light bearing 333°pgc. What is the position of your 0630 running fix?

The correct answer is determined by advancing the 0610 Montauk Point Light line of position based on the vessel's speed and run, then intersecting it with the 0630 Watch Hill Point Light line of position, resulting in a position of LAT 4108.3'N, LONG 7145.4'W.
