Nice large ferry. Snack bar and nice seating inside and out. $8.75 each way. $15 parking at Palmer st. Make sure you go to a parking area first. Plenty of shuttles.

Took the fast speed ferry to Nantucket with a group of 5 people. Service and staff were great, Best deal is the Steamship Authority is 20% cheaper than HY-Line out of Hyannis. Only issue is the parking. Happy sailing. Pete

Took their high speed ferry to Nantucket. It was a very large ship, had snacks and drinks, alcohol too, available for purchase. The trip was fast, about 1 hour and very smooth. The seats are very comfortable. Staff is friendly.

Have used the Fast Ferry for numerous trips to Nantucket. Always a great experience. You can enjoy the boat ride or simply sit and read for the full trip.

I love these vessels. You get to the islands quickly so you can spend more time there than getting there. The boats are comfortable and smooth with food and drinks.
