Radar, Collision Avoidance, and Night Navigation – Virtual Class

Jan 11–12, Mar 1–2, May 3–4, Oct 18–19 | 6:30–8:00 PM | $75
Learn to interpret the images your radar is displaying with video radar exercises from our simulator. This class includes an introduction to true and relative motion, range, bearing, and what that means to you and your vessel. You will also learn how to mark targets and track other vessels. Then, build on your basic radar skills with simulated navigation exercises in fog and darkness. Use vectors, bearing lines, and range rings to navigate safely. You will learn to recognize other vessels, aids to navigation, harbor entrances, and hazards at night. The class features video from our state-of-the-art maritime simulator, which accurately demonstrates the lights of Puget Sound and the vessels you might encounter. This class is offered via Zoom.

Charts and Dead Reckoning – Virtual Class

Jan 18–19, Mar 8–9, May 10–11, Sept 6–7, Nov 8–9 | 6:30–8:00 PM | $75
Navigation without a GPS! You’ll learn to use latitude, longitude, compass bearings, transits, and your paper charts to know where you are. This is an introduction to the traditional art of dead reckoning. This class is offered via Zoom.

Charting 201: More Charts and Dead Reckoning – Virtual Class

Jan 27–28 & Feb 3–4; Mar 17, 18, 24, 25; May 19, 20, 26, 27; Oct 6, 7, 13, 14; Dec 1, 2, 8, 9 | 6:30–7:30 PM | $75
A deeper dive into the world of using paper charts and dead reckoning to navigate safely. This class will involve more advanced charting problems, as well as a little homework between classes. We will include set and drift into our dead reckoning calculations, and learn more about variation, deviation, and compass error. You’ll have more chances to practice your skills with a compass, chart, dividers, and parallel rules—because the reality is that the most risky scenario is when your electronics go out!

No Impact Docking – Virtual Class

Feb 8–9, Mar 15–16, May 17–18, Jul 12–13, Oct 25–26 | 6:30–8:00 PM | $75
How to dock without fear (or damages)! No yelling! No leaping! We’ll see slides, handouts, and tips for successful docking strategies for keelboats and trawlers, and how to practice them. We’ll learn how to use prop walk, winds, and spring lines to your advantage…the finer points of docking without bow thrusters or twin screws. This class is offered via Zoom.

Tides & Currents in the Salish Sea – Virtual Class

Jan 25–26, Mar 29–30, Jun 15–16, Jul 26–27, Oct 4–5 | 6:30–8:00 PM | $75
Tides and currents are a huge part of boating in the Salish Sea. Knowing the forces at work, the resources available and the boat skills needed to safely operate is paramount to a successful on-the-water adventure. Kayak, inflatable, sailboat, or powerboat—all are affected by the rise and fall of the tide. Whether a day trip on Port Townsend Bay or a trip up the Inside Passage, this class will help you with safe boat-trip planning. This class is offered via Zoom.

Lights, sounds, right of way: know the rules! Who has right of way? Where’s the channel? By the end of this class, you’ll understand the maneuvering rules, lights, sound signals, and buoys that allow us to navigate safely around hazards and other vessels. This class is offered via Zoom.

Feb 15–16, Apr 12–13, Jun 21–22, Sept 27–28, Nov 15–16 | 6:30–8:00 PM | $75
This is an introduction to the many electronic tools and instruments that can help us navigate safely: Depth Sounders, GPS, Chart Plotters, AIS, Radar and VHF radios. The class features a discussion of the common errors associated with each system and what they can and can not tell you. Includes video from our Simulator, and a chance to practice mayday calls. This class is offered via Zoom.

Anchoring & Anchorages – Virtual Class

Feb 22–23, Apr 19–20, Jun 28–29, Aug 9–10, Nov 1–2 | 6:30–8:00 PM | $75
