Captained by the 55-year-old James Ferguson, the vessel left Stranraer's railway loading pier at 07:45 hrs with 44 tons of cargo, 128 passengers and 51 crew. Captain Ferguson had served as master on various ferries on the same route for 17 years. A gale warning was in force but he made the decision to put to sea. Loch Ryan is a sheltered inlet and the immediate force of the wind and sea was not apparent, but it was noted that spray was breaking over the stern doors. A "guillotine door" had been fitted, because of a previously identified problem with spray and waves hitting the stern doors, but it was rarely used, because it took too long to raise and lower. This would have provided extra protection for the sliding stern doors. On this occasion it was not lowered.
