Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###

### 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'?
