Horizon Lines Inc. and Pasha Hawaii Transport Lines said yesterday they are increasing their fuel surcharge between Hawaii and the mainland by 4.75 percentage points to 26.5 percent from 21.75 percent.

The increases, which match the one announced last week by rival Matson Navigation Co., will be effective Feb. 27, the same day as Matson. It is the shippers’ first increase in about a year.

Horizon, the state’s second-largest ocean shipper behind Matson, also increased its fuel surcharge for service between the mainland and Guam/Commonwealth of the Northern Mariana Islands to 28 percent from 23.25 percent, matching Matson. Both increases also are effective Feb. 27.

Pasha, which transports vehicles between Hawaii and San Diego, received state Public Utilities Commission approval last October to begin limited interisland cargo service in a decision that was challenged by incumbent Young Brothers Ltd. Pasha has yet to announce a start date.
