Ok I found them. For one way to or from Kahului, it was $59 per adult, $49 per child (mine was two at the time), $49 per senior, and $75 for acar under 8-ft. tall and 17-ft. long.
Never got a chance to use it... it was killed before I got a chance.
The per head price alone was covered by not needing to rent a damn car.
Just looked into going off island for a week end. Just the wife and I for our 5 year anniversary.
200 dollars a head for plane tickets (400) from maui to kauai
120 dollars for a rental car (60 dollars a day for two days)
120 dollars for a decent place to stay for the night.
So for a simple weekend overnight away in my home state, looking at 640... not including food, beverages and entertainment.
Superferry would have saved me $$$
we ended up driving to Napili, renting a condo for the night.
