CHESTER booked their place in the last 32 of the FA Trophy after a comfortable first round win in Humberside.
Striker Michael Wilde broke the deadlock in the 38th minute when he stabbed home from close range after home keeper Steve Wilson parried a Matty McNeil shot.
McNeil made it 2-0 in first half stoppage time when he swept home an eight yard shot from Wilde's low left wing cross.
And Wilde smashed home Chester's third goal from Antoni Sarcevic's corner three minutes after the break.
Matty McGinn saw his 54th minute penalty saved by Wilson after Sarcevic had been floored in the area.
And Ferriby reduced their arrears four minutes later when Paul Harsley converted a penalty awarded after Gary Bradshaw had been fouled by Alex Brown.
But Sarcevic made it 4-1 on the hour when he powered home an angled shot under the body of Wilson.
And Iain Howard wrapped up the tie with Chester's fifth goal in the 72nd minute after Wilde's right wing cross had been dummied by McNeil.
