In this June 30, 2007, file photo, a surfer catches a wave at Kakaako Waterfront Park as the Hawaii Superferry approaches Aloha Towers in Honolulu. Hawaii officials are exploring what it would take to run a ferry between islands. But they're facing skepticism over costs and whether there's a ferry system residents would accept. But the idea is bringing back memories of the Superferry, an emotional and expensive failure in Hawaii history. Years ago protesters blocked the Superferry from docking in Kauai. And a court later ordered the ferry to stop running because the state didn't do a proper environmental review. (Photo by Marco Garcia/AP Photo)
