Finnish ropax and cruise ferry owner Viking Line is experiencing heavy and growing demand for freight transport during the pandemic.
The company said volumes have remained high despite "exceptional circumstances".
It was surprised when the Easter holiday period proved to be busy, and demand has grown even further since then, it added.
The company is trying to safeguard the security of supply in Finland.
The emphasis is on guaranteeing imports of food and medicine, the company said.
"The volume of freight traffic has been heavy," Viking Line added.
Viking Line freight director Harri Tamminen said ships have reached 100% cargo capacity on several occasions.
Our staff has done an especially good job loading the cargo," he said.
He added the market shows no concrete indications of any volume reductions in the near future.
Five vessels on freight duty
Five Finnish-flagged ships are carrying cargo for the company currently.
"We have been able to optimise the schedule to be followed during this exceptional period, both in terms of timetables and traffic frequency, through good co-operation with our customers and by taking into account the transport needs of the market," said Tamminen.
At the end of March, Viking Line cancelled its 2019 dividend as the coronavirus pandemic hit passenger operations.
It had been due to pay out €0.45 ($0.51) per share for 2019, up from a €0.20 payout for the prior year.
Based on its 10.8m outstanding shares, this would save it $5.5m.
Earlier that month, Viking Line tore up the profit guidance it had given just the week before.
In its annual results, the shipowner said it had expected stable passenger numbers and higher sales per guest this year.
The company was at that point expecting operating income for 2020 to be on a par with 2019.
The Jan Hanses-led owner of seven cruise ferries posted $6.6m in net profit last year, against $8.8m during 2018.
Revenue came in at $496m, down slightly from $498m in 2018, and expenses declined from $499m to $479m.
