Jib 1 is our first class that goes into the advanced knowledge required to sail in heavy wind. You’ll learn how to effectively use a jib sail, perform man overboard rescues, and maneuver in the demanding conditions required for the Mercury red test. The Jib class is the heart of our Mercury sailing curriculum, and is designed to create competent sailors who are prepared for red test conditions. After learning how the jib sail works and how to rig it, you and another crew member will get on the water to try out your new knowledge. Your instructor will cover how to rig and trim the jib, how to coordinate your weight placement in the boat, and the procedure for man-overboard rescues. The instructor will join you on the water and coach you from a powerboat, so that each move you make is that of a solid and capable sailor. The Jib 1 class is typically taken several times before completing the test. Each time you take the class you will learn more from your classmates and instructors, and get extra practice for the demands of the test.

Jib 2 teaches the finer points of advanced boathandling and crew coordination. In this class, you will learn to sail without a rudder! Rudderless sailing, while not required for the red test, gives a sailor a deeper understanding of the forces at work when a boat is under sail. This class is focused specifically on sailing a boat using only the sails and your own weight; no rudder required. You’ll learn how sail trim and heel affect how a boat moves, so that you can make your turns better, tacks smoother, and gybes safer. Any sailor who has taken Jib 1, and wants to greatly increase their sailing knowledge, should take this class.

Jib 1 is our first class that goes into the advanced knowledge required to sail in heavy wind. You’ll learn how to effectively use a jib sail, perform man overboard rescues, and maneuver in the demanding conditions required for the Mercury red test. The Jib class is the heart of our Mercury sailing curriculum, and is designed to create competent sailors who are prepared for red test conditions. After learning how the jib sail works and how to rig it, you and another crew member will get on the water to try out your new knowledge. Your instructor will cover how to rig and trim the jib, how to coordinate your weight placement in the boat, and the procedure for man-overboard rescues. The instructor will join you on the water and coach you from a powerboat, so that each move you make is that of a solid and capable sailor. The Jib 1 class is typically taken several times before completing the test. Each time you take the class you will learn more from your classmates and instructors, and get extra practice for the demands of the test.
With demonstrations and boat simulators, Shore School explains all the theory you’ll need to start sailing. An experienced instructor will guide you through the basics of reading wind, trimming sails, steering a boat, and more. We’ll cover everything you need to know to get out and back to the dock safely, and you’ll even get a chance to practice these skills in our simulator located on the dock. and When you have completed this class, you’ll be prepared to take the Mercury green test!

Jib 2 teaches the finer points of advanced boathandling and crew coordination. In this class, you will learn to sail without a rudder! Rudderless sailing, while not required for the red test, gives a sailor a deeper understanding of the forces at work when a boat is under sail. This class is focused specifically on sailing a boat using only the sails and your own weight; no rudder required. You’ll learn how sail trim and heel affect how a boat moves, so that you can make your turns better, tacks smoother, and gybes safer. Any sailor who has taken Jib 1, and wants to greatly increase their sailing knowledge, should take this class.

Join our series of three evening classes designed to demystify the sport of sailboat racing and get you ready to compete — no experience required! Racing is a fun way to improve your sailing skills, get on the water more often, and meet a friendly group of CBI sailors. The three sessions — Introduction to Racing, Basic Racing Rules, and Basic Racing Strategy — will be offered on consecutive weekday evenings (see calendar) and will repeat throughout the season. The first meeting covers the basics of race courses, including starts, some beginner speed tips, a refresher on basic rules of the road, and what to expect of racing as a pastime, sport and social event. Lesson two dives deeper into the rules of racing, and how to avoid tricky, slow or contentious situations on the water. The final class includes speed tips, strategy, and ways to practice your craft.All three lessons are on land, but a companion clinic will be held during and/or after the course period to help put these new skills into practice. Mercury Yellow is required to register for this class. Registration can be completed through your Member Portal or in person at CBI.

Your instructor will cover how to rig and trim the jib, how to coordinate your weight placement in the boat, and the procedure for man-overboard rescues. The instructor will join you on the water and coach you from a powerboat, so that each move you make is that of a solid and capable sailor. The Jib 1 class is typically taken several times before completing the test.

Join our series of three evening classes designed to demystify the sport of sailboat racing and get you ready to compete — no experience required! Racing is a fun way to improve your sailing skills, get on the water more often, and meet a friendly group of CBI sailors. The three sessions — Introduction to Racing, Basic Racing Rules, and Basic Racing Strategy — will be offered on consecutive weekday evenings (see calendar) and will repeat throughout the season. The first meeting covers the basics of race courses, including starts, some beginner speed tips, a refresher on basic rules of the road, and what to expect of racing as a pastime, sport and social event. Lesson two dives deeper into the rules of racing, and how to avoid tricky, slow or contentious situations on the water. The final class includes speed tips, strategy, and ways to practice your craft.All three lessons are on land, but a companion clinic will be held during and/or after the course period to help put these new skills into practice. Mercury Yellow is required to register for this class. Registration can be completed through your Member Portal or in person at CBI.
