Seaspan Doris (IMO 6801925) - Vancouver Harbour- c1980 - Mr DOT photo ©
In other photos this vessel is categorized as a 'passenger vessel'. I don't believe that it has ever carried paying passenger. It spent its career moving freight (truck trailers & rail cars between the Canadian mainland (British Columbia) & Vancouver Island. It has a semi enclosed main deck and an elevator accessed upper freight deck. She is now laid up & likely to be disposed of soon.
