Social & Competitive Sailing

Community Boating offers racing almost every day of the week! Racing is a fun and challenging way to get more out of the sport. It provides an opportunity to reinforce and build your sailing skills while becoming part of a friendly and competitive community. Hone your boat handling through competition and learn racing rules and strategies through classes. See our different racing opportunities below and learn how get involved, whether you’re a seasoned vet or completely new to sailboat racing.

Friday Night Informal Racing

CBI staff 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.

Learn To Race

Tiller Club volunteers teach classes and clinics designed to introduce sailors to the competitive sport, and to expand the horizons of experienced racers.

Learn to Race Class Series

Our Learn To Race class series is designed to demystify sailboat racing for the intermediate sailor with little or no racing experience. The course is taught in three 90-minute chalk talks — Intro to Racing, Basic Racing Rules, and Basic Racing Strategy.

While all three lessons are on land, the instructor will also provide details on several opportunities to put your new skills to the test on the water, including those below and at

Who: Members with Mercury Yellow rating (Jib class suggested)
When: See schedule and sign up in advance through the Online Member Portal

Novice Racing Clinics

For first time racers, this companion clinic will help put new skills and knowledge from the Learn-to-Race classes into practice. Learn through practice starts, races with on-the-water support, and a debrief afterwards. Tiller Club members will help introduce first-time racers to the sport, directing them to understand the course, locate the marks, and comprehend the starting sequence in order to get around the course properly their first couple times.

Who: Members with Mercury Yellow Rating who have taken LTR part 1

Intermediate & Advanced Instruction

CBI volunteer instructors run intermediate race practices geared towards regular CBI racers.

High Performance Racing

We’re a friendly group of CBI members interested in the speed and excitement of sailing and racing 420’s and Lasers. Our group is dedicated to improving our sailing skills, while having fun on the water through informal racing. Most weeks, we run several short races with no score-keeping, so boats may join at any point in the evening.

Who: Whether you were a college all-American or just learned the racing rules through CBI’s Learn To Race class series, you’re welcome to sail with us. A 420 or Laser rating is required to skipper. Crew may have any rating, but must match up with a skipper.
When: Monday evenings starting after 17:00. We head out to race as soon as a few boats are rigged and a course is set. Racing ends 30 minutes before sunset.
Where: CBI main dock, rain or shine. If arriving late, meet us on the racecourse.

Contact & Updates

To see important updates, ask questions, or match up with a crew/skipper, join our CBI High Performance Racing google group. Or subscribe by sending a blank email to [email protected].

Note that Google Groups allows you to control the frequency of emails as there is often a high volume on summer Sundays/Mondays.

Women’s Racing and Sailing

The mission of Women’s Sailing and Racing is to advance the sailing skills of women at CBI through racing and practice in a challenging, supportive, and social environment. We welcome women at all levels of experience interested in participating in recreational or competitive sailing and skill development.

Social Sailing on Tuesdays: Women of all skill levels are welcome Tuesdays. It’s an opportunity to meet friends, expand your sailing skills and share the joy of sailing.

Racing on Thursdays: Our racing is informal and focused on skill development. Experience with a jib and/or a yellow rating is ideal to start to crew. The first time you join us for racing, please select a day where you have the flag-rating. We either pair up on the dock or on Slack so you do not need to bring crew.

To stay up to date join our Google Group or our Slack channels (email front office for access, [email protected]).

Co-able Keelboat Racing

An inclusive group of CBI members interested in the teamwork and power of sailing and racing Sonars and Ideal 18’s. We’re dedicated to improving our sailing skills and building camaraderie, while having fun on the water through informal racing.

Co-able Keelboat Racing is organized by CBI staff every Wednesday Night starting in May, and will race on Sonars and Ideal 18s. Sailors include members from both the Adult Program and Universal Access Program. We hold a competitors’ meeting at 17:30 to brief sailors about the course, rules, and answer questions. We return to the dock approximately 30 minutes before sunset and hold a debrief on shore.

All are welcome to attend; UAP members should RSVP below:


Intermediate Racing Practice

Intermediate Racing Practices mailing list will be used to organize informal sessions where experienced racers can practice and improve their racing skills. While there is no regular schedule, anyone on the list can propose and organize a practice. These might involve a few boats or many boats and work on various skills depending on the interests of the organizers and participants. Advanced racers may sometimes volunteer to provide formal or informal coaching at these practices.

The general expectation is that skippers in the practices should:

  • Know the racing rules
  • Have skippered in at least a few Tiller Club, Women’s Racing, or Friday Night races
  • Have Mercury red rating
  • Crew should have some racing experience but need not have red ratings nor rules expertise

Organizers of particular sessions may tailor these requirements depending on the goals of the practice. Sign up for the email list:

Windsurf & SUP Racing

The CBI Windsurfing Community is a diverse group of people, who share a love for water sports; world class windsurfers and beginners having fun and learning from each other. We race the BIC One Design 293 with a 7.8 rig, but you can go with a smaller sail if you feel more comfortable (or more competitive).

Who: All windsurfers with a yellow rating are welcome, whether you’re a pro or just learning the racing rules through CBI’s Learn To Race class series.
When: Every Tuesday at 17:30 (rigging starts earlier). We will run several races, and go until sunset
Where: Meet at the windsurf shed. Don`t forget to check out at the dockhouse before rigging.

-One of many excellent quizzes to improve and test your knowledge of the Racing Rules of Sailing

-Part of a wonderful series on mainsail tuning and shape

-Roll tacking timing and footwork. Finish on close-hauled and with the rudder straight!
The best one for CBI members to emulate is at 1:53 (light wind)
Really nice focus on initiation, patience, footwork, and tiller hand. See the heel of the aft foot at 3:59! (moderate wind)
For the Mercury it’s more about patience and smoothness than the muscle and speed displayed on these small collegiate dinghies.
Laser roll tacking requires quite a bit more physicality than the 420 or Mercury
