Hello! Does anyone have any information concerning this Co.? The Colonial Line was a branch of the Colonial Navigation Co.,which is still in operation with different types of vessels. During the 1930s the Colonial Line provide passenger/car tranport service between NYC and Providence,Rhode Island with rail connections to Boston. I am researching this company and the vessels it owned before and after WW2. The ships SS Comet,SS Arrow, and SS Meteor were some of the ships of the line.
