Here are the rest of my results for Silicon Sea Leg 57. 4. ETA Cape Horn = Mar 26 0230 Z, Mar 25 2230 ZT. I divided the 297 miles measured on plotting sheet by 11.1 kt speed (10.3 kt plus .8 kt current practically on our stern). Since the current was stated, I assumed we were supposed to use it. 5. Distance from 2342 Z fix to Cape Horn = 297 nm. 6. Compass course = 100. 7. TC & dist to decision waypoint = 76 deg, 146 nm. Constructed a new plotting sheet for this question. 8. Compass course = 66. The problem says drift is "0.8 Kts/day". I assumed this meant 0.8 kts. My E-6B says we should angle 2 deg right to correct for that much current. Subtract the total compass error of 12 E to obtain answer.
