Select classes may be added throughout the season.
Green: Light to Moderate Winds. No Restrictions.
Yellow: Moderate Winds. Restrictions on beginner sailors; on-the-water testing may be available.
Red: Moderate to Strong Winds. Restrictions may be in use, and advanced testing may be available.
You can find out what the flag is by calling the dock phone (617-523-9763) or by visiting the CBI website.
The Restrictions are used when the winds become stronger than what may be safe for a particular rig, boat, or rating. They are for your safety, so please respect them.
This is when a member with a Mercury Yellow Rating or higher volunteers to take you out for instruction. Simply come to the Dockhouse with your membership card, and tell the staff that you would like to be added to the queue. When a member comes down to sign out a boat and if s/he is willing to give instruction, we will call your name over the loud-speaker.
Mercury Green Test: Any time when the program is open.
Green Test: Green ratings for any boat other than a mercury are given automatically upon completion of the requisite class.
Yellow Test: On a Yellow or Red Flag day when conditions permit (around 9-14 K).
Red Test: On a Red Flag day when the winds are approaching whitecaps.
Kayak: Any day when the program is open.
Sailors have two options to practice for their tests.
Each test has an accompanying class to help prepare sailors for that test; Jib class prepares for the Mercury Red test where Mainsail class prepares for the Mercury Yellow test. In these classes, your instructor will give you ample time to practice your skills.
If you wish to practice outside of class time, certain restrictions will allow you to practice in wind you are not yet rated for. Usually, this means going out with a reefed sail or a keel mercury. Always check with the dockhouse before going out for practice. Usually the dockstaff will make accommodations that will allow you to practice safely.
Once you have passed the Mercury yellow test (or any higher rating), you can bring guests aboard! The number of guests is limited to boat capacity. For kayaking, you are allowed one guest with you in a double kayak, once you have done your kayak check-out. Guest privileges are available for purchase at any point of your membership for $25.
Guests should complete and turn in a Guest Application (also available online here) and obtain their complimentary guest card at the front desk. This card is valid for the entire sailing season, and must be given to the dockhouse with the member’s card when checking out a boat. If lost or forgotten, the office can issue you a complimentary replacement. Guest applications can be filled out at the front office, or ahead of time on the CBI website.
Registering your guests online in advance allows you to skip the Front Office paperwork. It’s easy to do and takes less than a minute! Just have your guest bring their ID and show the Front Office, and they’ll receive a guest card.
Yes! As long as guests are accompanied by a parent or guardian, you may take out your guest on any boat with the capacity. Parents/guardians must sign a waiver for children 10-17. For guests under the age of 10, guests are restricted to keel boats.
Mercury Green Rating: To go sailing on your own, you need to take an Orientation class, a Rigging class, and a Shore School class in order to pass the Rigging test and a verbal test to earn your Mercury green rating (formerly known as Solo Rating). This will allow you to sail in a Cape Cod Mercury sailboat on green flag days.
Mercury Yellow Rating: To be able to take guests out sailing and to sail on yellow flag days, you will need to pass your Mercury Yellow test (formerly known as Helmsman Test). You may take the Mainsail class or take informal instruction to prepare for your Mercury Yellow test. For more information, visit the Resources section.
Mercury Red Rating: To be able to sail on red flag days, you will need to pass your Mercury Red test (formerly known as Jib Test). You may take the Jib 1 and 2 classes to prepare for your Mercury Red test.
Advanced Ratings are available and require you to take the Advanced Classes for a nominal fee of $35. Visit the Classes section for more information.
