This is an introductory class but is not a course for beginning sailors. To sign up for the course, sailors must have previously sailed in Intermediate Widgeons or Intermediate and Racing Optimists for a minimum of four weeks (the four weeks can be cumulative over multiple seasons). 420s are performance boats. Due to their size and speed, they are not ideal for small or lightweight students. Sailors who have not yet sailed at BSS should contact the program administrator to discuss their experience before signing up.
