Learn how to confidently use radar, AIS, and chartplotters together to navigate safely, avoid collisions, and make informed decisions in busy waterways and low-visibility conditions.

Live Q&A
This online class on radar and AIS will help sailors understand the complete electronic picture when navigating among other vessels. You’ll learn from Captains Ben and Teresa Carey on how radar and AIS complement each other, what each system can and cannot detect, and how to interpret overlapping information into one coherent understanding of the traffic around you. We’ll also discuss reduced visibility. Fog and darkness demand more than electronics—you'll learn to integrate radar, AIS, chartplotters, sound signals, and disciplined lookout practices into a complete strategy for navigating safely when you can't see your surroundings. We’ll share real-world experiences from Coast Guard reports on near misses and our real-world experience managing traffic and limited-visibility conditions during our coastal sailing trips, our recent transatlantic crossing, and our current cruise in the Mediterranean.

Online class overview

Learn to navigate with confidence using radar, AIS, and chartplotters in this practical online class with Captains Teresa Carey and Ben Eriksen Carey. Discover how these essential navigation tools work together to improve situational awareness, identify surrounding vessel traffic, and prevent collisions. Through real-world experiences and practical examples, you’ll learn to interpret radar and AIS information, recognize electronic blind spots, and apply effective navigation strategies in fog, darkness, and busy waterways. Whether you’re a coastal cruiser or offshore sailor, you’ll gain the skills to make informed decisions and navigate safely when visibility is limited.

Who is this online class for?

This online class is for sailors who are considering purchasing a radar and/or AIS or who already have them and want to use them with confidence. This online class is ideal for coastal cruisers, offshore passage-makers, charter boat sailors, and anyone who has looked at a radar screen and wondered what they’re actually looking at. Whether you’re preparing for your first night passage or you’ve crossed oceans, we’ll give you practical frameworks for interpreting what your electronics are telling you—and knowing when to trust them and when to question them. You’ll leave with a clear mental checklist for collision avoidance and low-visibility navigation that you can apply to your next sail.
