Schema: CREATE TABLE table_name_80 (olympics_so_far INTEGER, class VARCHAR, sailors VARCHAR, first_og VARCHAR)
Question: What is the lowest value for Olympics, when Sailors is greater than 1, when First OG is after 1948, and when Class is "Flying Dutchman"?
SQL: SELECT MIN(olympics_so_far) FROM table_name_80 WHERE sailors > 1 AND first_og > 1948 AND class = "flying dutchman"
