    4. Navigation Chapter 9 Practice Cruise Homework

    5. Using VPP2, start planning the cruise from Straits of Juan de Fuca, (L 48° 24.0´ N, Lo 124° 45.0´ W) to Honolulu, HI. Create a new passage in VPP2 and enter your departure and destination waypoints Practice Cruise 5

    6. Practice Cruise 6

    7. Before you can investigate various optimized courses in VPP2, you need to create a Vessel Profile for Ocean Passage. Print copy and file in your Navigator’s Notebook. Practice Cruise 7

    9. Practice Cruise

    10. Run several iterations of VPP2’s Optimization Routine for the month of June. Select one of your June optimized routes and edit the waypoints of your selected route to match the waypoints in the table on next slide. Print the “Passage Summary Report” for the June optimized routes, and file it in your Navigator’s notebook. Practice Cruise 10

    24. You plan to use Capn’s Trip Log feature with the GPS connected for an electronic log of the voyage. Run the simulation for five minutes at 100.0kn; at that point, slow the ship down to 5.0-10.0kn and change course to 270°T (to simulate reaching a waypoint and changing heading), and increase the speed back to 100.0kn. After an additional few minutes of running the simulation, click “Stop Logging” and print the resulting Trip Log for your Navigator’s notebook. Practice Cruise 27

    27. Display your route to Honolulu in Capn on a chart so that the entire route can be viewed. Print a copy of this route, and file in your Navigator’s notebook. Practice Cruise 30

    28. You plan to use celestial techniques frequently during this voyage. Your GPS position is L 47° 29.6´ N, Lo 125° 36.4´ W and your DR position is L 47° 32.4´ N, Lo 125° 37.0´ W. Winds are northwest at five knots and the knotmeter log reads 0062.3. At WT 14-00-16, you observe the moon UL at a sextant reading of 14°11.9´. At WT 14-01-12 you observe the sun LL with an hs of 59° 00.1´. Reduce both bodies using the NASR method and plot the resulting 2-body fix on a CLS plotting sheet. Practice Cruise 32
