No.

You will receive an on-screen booking reference number, which will be sent to you by email.

You will get your tickets when you arrive at the port but you have to present the booking reference number with a photo ID at that time.

I traveled with Norfokline a few weeks ago.

It operates as a ticket less company.

I made an online reservation and they sent an email confirmation containing the booking reference number and travel details.

But on the day of travel you will need to quote the booking reference number at the Norfolkline check-in booth.
