SELECT (SELECT "launch year" FROM table_204_431 WHERE "yacht" = 'morna') = (SELECT "launch year" FROM table_204_431 WHERE "yacht" = 'toyota aurion')
SELECT (SELECT "launch year" FROM "table_204_431" WHERE "yacht" = 'morna') = (SELECT "launch year" FROM "table_204_431" WHERE "yacht" = 'toyota aurion')
