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 ###
TABLE: CREATE TABLE table_53870 ( "Ship" text, "Built" real, "Entered service" real, "Route" text, "Gross tonnage" text, "Length" text, "Width" text, "Passengers" real, "Vessels" real, "Knots" real )

### Question ###
What is the most recent built year when the year of entering service was more recent than 2003, and the knots is less than 27?

### Accurate SQL ###

SELECT MAX("Built") FROM table_53870 WHERE "Entered service" > '2003' AND "Knots" < '27'
