HONOLULU -- A Kauai judge on Friday rejected a request from a citizens group for a temporary restraining order to ban the Hawaii Superferry from docking at Nawiliwili Harbor.

A TRO is already in effect on Maui. A Maui judge will decide on Monday whether the ban will remain until the environmental review is finished.

The Hawaii Superferry on Thursday informed the court that it would sail to Maui's Kahului Harbor on Saturday to return passengers and their vehicles between the Valley Island and Oahu. The court granted the move in August.

Superferry officials, the Coast Guard, the Sierra Club and the state Department of Transportation stood together on Friday to make sure the vessel will be allowed to dock in Maui Saturday without incident.

They do not want a repeat of the protest on Kauai as demonstrators took to the water and blocked the vessel from docking.

They wanted to stress that Saturday's voyage is court approved.

"We have talked to the canoe clubs looked at the other commerce that's occurring within the port, and we have ensured ourselves and the water use that this would be a good time for that one run to be made to allow 60 people to retrieve vehicles from Maui and a lesser amount to bring their vehicles back," U.S.C.G. Adm. Sally Brice O'Hara said.

Ferry passengers on Oahu have been told to arrive at the docks no later than 10:30 a.m. on Saturday at Pier 19 in Honolulu. The vessel is scheduled to leave Honolulu at 11 a.m. and arrive on Maui at 2 p.m. It is expected to return to Oahu at about 6 p.m.

The Coast Guard said it has been told that one group has applied for a permit to demonstrate on land.

Maui police said they have heard from the Superferry and the Pacific Whale Foundation, but no one knows for sure what demonstration, if any, takes place.
