So, you’re looking at that little gray lady in the distance and trying to figure out how to actually get there. Honestly, if you just Google "ferry from Cape Cod to Nantucket," you'll get a wall of schedules that look like a math textbook. It's confusing. You’ve got fast boats, slow boats, car boats, and the seasonal ones that only run when the sun is out.
Most people just click the first link they see. Huge mistake. Depending on whether you're bringing a dog, a bike, or a literal SUV, the "best" ferry changes completely.
The Hyannis Showdown: Steamship vs. Hy-Line
Basically, if you’re leaving from Cape Cod, you’re almost certainly leaving from Hyannis. This is the hub. You’ve got two main players here: the Steamship Authority and Hy-Line Cruises. They are about a ten-minute walk from each other, but they feel like different worlds.
The Steamship Authority is the "official" one. They run the big, heavy-duty ships that carry cars. If you want to take your Jeep to the island—which, by the way, requires a reservation you usually have to make in January—this is your only option. They also have a high-speed passenger-only ferry called the M/V Iyanough. It gets you there in about an hour.
Then there’s Hy-Line. They’re the "fancy" choice, sorta. They only do passengers (no cars). Their high-speed ferries take the same hour, but they offer things like "Captain’s View" seating where you get pre-assigned seats and a better view.

Here is the real talk on pricing for 2026:
A round-trip on the fast ferry is going to run you about $90 to $95. If you’re a budget traveler, the Steamship Authority’s "slow boat" (the traditional ferry) is your best friend. It’s roughly $45 round-trip. The catch? It takes two hours and 15 minutes. It’s a long haul, but honestly, on a sunny day with a beer in your hand on the top deck? It’s kind of the best part of the trip.
The Parking Nightmare Nobody Mentions
You cannot just roll up to the dock 10 minutes before departure and expect to find a spot. Hyannis parking is a logistical puzzle.
Hy-Line has some on-site parking, but it’s expensive—think $20 to $30 a day in the peak of summer. The Steamship Authority mostly uses off-site lots. You park your car miles away, and then you wait for a shuttle bus to take you to the terminal.
If you are taking the 9:00 AM ferry, you need to be at that parking lot by 8:00 AM. Seriously. If the lot is full, they’ll divert you to another one even further away. Most people miss their ferry because they underestimated the shuttle ride. Don't be that person.

Bringing a Car: Is It Worth the Hassle?
Probably not.
Look, Nantucket is tiny. Unless you are staying for a month or you’re a contractor with a van full of tools, a car is a liability. The streets in town are cobblestone and narrow. Parking is a nightmare.
If you must bring one, you’ll be paying anywhere from $300 to $500 round-trip for that vehicle reservation on the ferry from Cape Cod to Nantucket. And again, those spots sell out the second they go live on the Steamship Authority website in early 2026.
The Seasonal Alternatives
If you aren't in Hyannis, you aren't totally out of luck.

- Harwich Port: Freedom Cruise Line runs out of Saquatucket Harbor. It’s a smaller operation, which makes it feel a bit more "Old Cape Cod." It’s seasonal (usually starting in May), and it drops you off at Straight Wharf.
- New Bedford: Okay, technically not Cape Cod, but Seastreak runs a ferry from New Bedford. If you're coming from New York or Rhode Island, this is a massive time-saver because you skip the bridge traffic.
- Martha’s Vineyard: Already on the other island? You can hop between them on an inter-island ferry. It’s a gorgeous hour-long ride, but it only runs in the summer.
Pro Tips for the Actual Crossing
The Atlantic is moody. Even in July, the "Grey Lady" (Nantucket’s nickname) gets foggy. If the wind kicks up over 25 or 30 knots, the fast ferries might stop running. The big slow boats? They almost always sail. If you have a flight to catch or a wedding to get to, keep an eye on the weather.
- Pets: Both lines allow dogs. Steamship is pretty chill about it; Hy-Line usually requires them to be on the deck or in a carrier.
- Bikes: You’ll pay about $16 round-trip to bring your bike. Do it. It’s the best way to see the island.
- Seasickness: If you’re prone to it, take the slow boat. It’s a much steadier ride than the catamarans that "bounce" over the waves.
What to Do When You Land
When the ferry pulls into Nantucket, you’re right in the heart of town. You don't need a cab to find a good meal. Straight Wharf and Steamboat Wharf are lined with shops.
If you’re heading to Siasconset or Madaket, grab "The Wave" bus. It’s cheap, reliable, and way easier than trying to navigate a rental car through a sea of tourists.
To make this travel day work, download the Steamship or Hy-Line apps ahead of time. They give you real-time updates on delays, which happen more than you’d think. Book your parking in advance if you’re using a private lot, and for the love of everything, double-check which wharf your return ferry leaves from. They aren't the same.
Actionable Next Steps:
- Check the 2026 Calendar: If you're traveling between June and August, book your passenger tickets at least three weeks out.
- Confirm Your Terminal: Put "69 South Street" (Steamship) or "220 Ocean Street" (Hy-Line) into your GPS, not just "Nantucket Ferry."
- Monitor 1610 AM: If you’re driving into Hyannis, tune into this radio station for live parking lot availability updates.
- Pack a Windbreaker: Even if it's 80 degrees on the mainland, the breeze on the Sound will make it feel like 60.
