The Northern California Yacht Clubs and PCISA host a series of races for High School teams from Northern California only. There are two tiers of regattas: "One-Days" (those for the more entry level teams/sailors that require only two kids from the same school). And "Divisional Regattas" (those for full teams of at least four sailors, which mimic the PCISA Regattas). 8th graders may sail for the school they intend to enroll in for 9th Grade as long as they are paired with a current student from that High School.
Pacific Coast Interscholastic Sailing Association (PCISA) schedules a series of CFJ races hosted by PCISA and ISSA, during the school year. Schools enter one team with an A and B Division and sailors rotate boats throughout the regatta. A full team is at least 4 sailors where at least 3 are from the same school. Only teams where all 4 sailors are from the same school can advance to the Pacific Coast Championship (PCC). The combined scores for the series qualifies a school for the PCC's, with the top 4 schools advancing to the ISSA National Championship. 8th Graders sail for the high school they intend to enroll in and may not sail in District Qualifiers and/or National Championships.
Bay Area Youth Sailing (BAYS) offers a series of races for junior sailors to represent PYSF and race in the following fleets: Opti Green, Opti Championship, Laser Full, Radial, 4.7, CFJ, C420, and 29er. These regattas occur over the Fall, Spring and Summer months. It is highly recommended that sailors compete in the regattas laid out in the schedule.
