It's close to that time of year when the "bus" is parked and charts/trip planning dance in my head. For this exercise I've taken a screen shot of popular kayaking destination Stonington. I hope some may find this a useful exercise, though no substitute for one-on-one chart-and-compass work. Feel free to submit your own practice questions for this "chartlet", perhaps adding answers as I have. Likely easiest to work through by printing out (choose "grayscale printing" to save your color inks). 1. 1. An early morning start from Duck Harbor, IAH, has put your group in good position to meet another paddling group at Green I. quarry, for lunch and a swim on this hot July day. After leaving Harbor I. in a northerly direction, an unexpected fog bank rolls in, and your group finds itself “at sea” as to your location. Your non-mapping, primitive Garmin hand-held displays “68.38.367W 44.07.153N”. Approximate the position of your group on the chart, then pinpoint your precise location after doing the math. 2. 2. You have not loaded waypoints for the quarry into your GPS, so you will calculate the waypoints, using the tip of the cove on Green Island’s SE shore. 3. 3. After a restful and playful afternoon at the quarry, pre-sunset, it’s time to make for home base. Russ, a relatively green navigator, thinks he might have a devil of a time locating our camp on Hell’s Half Acre. He’s asked you for help finding the shortest route back “home”. Walk him through the process, including bearings, features, aids to navigation, and ETA. 4. 4. The next day, a few in the group decide to visit MITA’s recently-added George Head I.. As you round the southern shore of Coot I., someone claims to make out Wreck I. behind Bare-Yes or No? From here, one should be able (good visibility/?binoculars) to point out (Yes, No Maybe)?: Sprout, John, Buckle/Spruce, near Potato, far Potato, George Head, Little George Head. Round, St Helena (duh-look for the smoking volcano). 5. 5. Triangulation exercise: E of John I. you take bearings of 84 and 05 degrees, magnetic to RN “4” and “2”, respectively. Where are you on chart? What is your GPS waypoint? Radio your location to Coast Guard, using back bearings. 6. 6. What distinguishing intrinsic feature(s) might separate Devil and Camp from your position in exercise 5 above? navexer#3.pdf Answers: Nav exercise 3 answers.docx gary
