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.

Fri, Sep 4, 2026, 5:30pm - 7:30pm

Members organize several short races most Fridays after work. Racing is informal, so boats can join at any point in the evening. A social atmosphere blending camaraderie, fun, sailing, and competition; meet new people and broaden your sailing horizons.

Who: All skill levels welcome; whether you’re a national champ or are just learning you’re encouraged to sail with us.
When: Rig anytime and head out to race as soon as a few boats are ready and a course is set — usually about 17:30. Racing ends at sunset, so come out even if you free up a bit later.
Where: Meet on the water. Look for a cluster of Mercuries, the nearby committee boat flying flags & sounding horns, and big red tetrahedrons.
What: You can race mainsail, sloop or spinnaker, solo or with friends, keel or centerboard, as long as it’s a Mercury.

See our blog below for updates, rules & racing tips, watermelon announcements, and hilarity. Sign up for email updates so you don’t miss a post; typically weekly or less:

Sat, Sep 5, 2026, 4:00pm - 6:00pm

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.

Members organize several short races most Fridays after work. Racing is informal, so boats can join at any point in the evening. A social atmosphere blending camaraderie, fun, sailing, and competition; meet new people and broaden your sailing horizons.

Who: All skill levels welcome; whether you’re a national champ or are just learning you’re encouraged to sail with us.
When: Rig anytime and head out to race as soon as a few boats are ready and a course is set — usually about 17:30. Racing ends at sunset, so come out even if you free up a bit later.
Where: Meet on the water. Look for a cluster of Mercuries, the nearby committee boat flying flags & sounding horns, and big red tetrahedrons.
What: You can race mainsail, sloop or spinnaker, solo or with friends, keel or centerboard, as long as it’s a Mercury.

See our blog below for updates, rules & racing tips, watermelon announcements, and hilarity. Sign up for email updates so you don’t miss a post; typically weekly or less:

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.

Members organize several short races most Fridays after work. Racing is informal, so boats can join at any point in the evening. A social atmosphere blending camaraderie, fun, sailing, and competition; meet new people and broaden your sailing horizons.

Who: All skill levels welcome; whether you’re a national champ or are just learning you’re encouraged to sail with us.
When: Rig anytime and head out to race as soon as a few boats are ready and a course is set — usually about 17:30. Racing ends at sunset, so come out even if you free up a bit later.
Where: Meet on the water. Look for a cluster of Mercuries, the nearby committee boat flying flags & sounding horns, and big red tetrahedrons.
What: You can race mainsail, sloop or spinnaker, solo or with friends, keel or centerboard, as long as it’s a Mercury.

See our blog below for updates, rules & racing tips, watermelon announcements, and hilarity. Sign up for email updates so you don’t miss a post; typically weekly or less:

Sat, Sep 19, 2026, 4:00pm - 6:00pm

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.

Who: All skill levels welcome; whether you’re a national champ or are just learning you’re encouraged to sail with us.
When: Rig anytime and head out to race as soon as a few boats are ready and a course is set — usually about 17:30. Racing ends at sunset, so come out even if you free up a bit later.
Where: Meet on the water. Look for a cluster of Mercuries, the nearby committee boat flying flags & sounding horns, and big red tetrahedrons.
What: You can race mainsail, sloop or spinnaker, solo or with friends, keel or centerboard, as long as it’s a Mercury.

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.

Members organize several short races most Fridays after work. Racing is informal, so boats can join at any point in the evening. A social atmosphere blending camaraderie, fun, sailing, and competition; meet new people and broaden your sailing horizons.

Who: All skill levels welcome; whether you’re a national champ or are just learning you’re encouraged to sail with us.
When: Rig anytime and head out to race as soon as a few boats are ready and a course is set — usually about 17:30. Racing ends at sunset, so come out even if you free up a bit later.
Where: Meet on the water. Look for a cluster of Mercuries, the nearby committee boat flying flags & sounding horns, and big red tetrahedrons.
What: You can race mainsail, sloop or spinnaker, solo or with friends, keel or centerboard, as long as it’s a Mercury.
