The Hawaii Superferry operator will hold a free community preview on board the Alakai from 11:30 a.m. to 4 p.m. tomorrow.

Because of harbor security, anyone planning to attend must register in advance on the www.HawaiiSuperferry.com Web site.

The names of all people in the party must be registered, with no additions accepted on-site. Adults must have photo identification.

Parking will be available at the harbor; look for gate signs on Kawaihae Road.

Hawaii Superferry will start service Tuesday with travel between Maui, Kaua'i and O'ahu. Big Island service will start in 2009.
