TISC Junior Sailing Program runs rain or shine. If conditions are deemed unsafe, classes will be canceled and parent will be notified by text through the Dial my Call.

Prior to, or on the first day of Program, parents will complete a “Dismissal Form” for their child. This form will contain a list of the names of approved adults who are able to pick up the student from program. This form also allows for a notation regarding the student’s ability to take public transportation home by themselves. At the end of each day, students are signed-out and dismissed either to an approved adult or are allowed to walk to public transportation.

TISC offers a wide range of adult classes on a variety of boats including Adult Dinghy, Basic Keelboat 1, Skills  Days, Advanced Keelboat, and private lessons. Information on all of these classes is available through our Adult page.

Prior sailing experience is generally not required unless specified in the course description (i.e. Advanced Keelboat or Skills Days).

To register for an adult sailing class please visit our Adult page or contact TISC via email at programs@tisailing.org.

Community sailing at TISC is open to everyone who is interested. TISC also welcomes toddler’s and young children to participate at the parent’s discretion given compliance to all safety procedures and direct parent supervision.

Imagine the independence a child feels the first time at the helm of a sailboat. Experiential learning is extremely important for building self-confidence and encouraging a child’s critical thinking. At the Treasure Island Sailing Center we provide the opportunity for children to learn these valuable lessons while cultivating a love for the sport of sailing. If you are a lifelong sailor or if you have dreamed of sailing on the bay you can appreciate the fantastic experiences a youngster will have by participating in our classes. You can contribute here!
