The company said a date for commencing service to and from Kaua'i has not yet been determined.

"We have already begun community outreach efforts on Kaua'i." said Hawaii Superferry CEO John Garibaldi. "We will make our decision about when we commence our Kauai service once that process is completed."

The Superferry was forced to halt service to Maui after the state Supreme Court ruled that the state needed to conduct a study of ferry-related environmental impacts.

The court sided with environmentalists who argued the ferry could be harmful to whales and could transport invasive plant and animal species between islands.

The state Legislature revised state law in a special session that paved the way for the ferry to resume service.

"We appreciate the support we've received from everyone who shares the vision of uniting our islands and families by sea," said Garibaldi.

The Superferry will leave Honolulu daily at 6:30 a.m. and arrive in Kahului at 9:30 a.m. It will depart Kahului at 11 a.m. and arrive in Honolulu at 2 p.m.

The Superferry said after its initial $29 fare it will offer $39 one-way fares beginning Dec. 21 and through March 12, 2008.

The company said reservations will open at 6:00 a.m. tomorrow. These special inaugural fares will only be available on an advance-purchase basis and reservations must be made online through www.HawaiiSuperferry.com or through the call center at 877-HI-FERRY (877-443-3779). The call center is open daily from 6 a.m. to 7 p.m. HST.

The company said a reduced passenger vehicle fare will also be offered at $55 each way. Motorcycles, scooters, and mopeds are $35. All promotional fares are subject to applicable Hawai'i taxes and fees. The fuel surcharge has been waived for these promotional fares.
