  1. Not really North Shore, nor nautical, but these land-based exercises go a long way to improving your sense of "place" on the water, by recognizing features of your surroundings, and practicing plotting courses, while using your always-present-on-the-water orienteering compass.
  2. PART 1: April 20 9-2pmPART 2: May 19 10-3pmThe Rock, Paddle, Surf Kayak Coaching (RPS) Coastal Navigation course consists of two on-the-water sessions. The goal is to develop skills for safe and enjoyable kayak navigation along the coast (within five miles of land). Day 1 starts with an on-beach (weather dependent) discussion of tides, weather, wind, waves, swell, boat traffic, and wildlife. It continues with an introduction to the marine chart, and the use of a compass. The on-water segment is initially focused on “H2O Orienteering”, with the goal of using the environment, chart, and compass to determine location and direction. The topics include bearings, back bearings, topography, buoys, landmarks, and shore curvature. Rules of thumb related to the on-water estimation of distance and angles are discussed. Day 2 of the course involves moving on the water, including exploitation of transits, bearing compensation for wind and current (steering off), ferry angles, and parallax. Location: Both sessions will be in Boston Harbor. Registration covers both days. The course will be co-lead by Kevin Beckwith (British Canoeing Advanced Sea Kayak Leader and ACA Advanced OWI) and Bob Levine (British Canoeing Advanced Sea Kayak Leader and ACA OWI)PLEASE USE LINK BELOW TO REGISTER:http://www.salemkayak.com/reserve/coastal-navigationNote that Newbury Kayak rents drysuits and has navigation materials available.
  3. 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
  4. until
    Navigation Workshop April 24th - 1-5pm Gould Barn - 1 Howlett Street, Topsfield, MA Instructors: Phil and Lorrie Allen, Bob Levine, and Kevin Beckwith. This will be a hands on session (so less presenting and more doing) working with folks on everything from basic compass use and chart reading, to trip planning, calculating vectors, etc. The basic idea is to learn/review the material here and then practice on the water throughout the season. We will have charts from a variety of areas to explore. Attendees should plan on bringing a hiking compass and whatever other tools they may have / prefer to use.
