The Steamship Authority is the public ferry line that carries most people, and every car, to Martha’s Vineyard and Nantucket. It runs two main routes from Cape Cod: Woods Hole to the Vineyard in about 45 minutes, and Hyannis to Nantucket in about 2 hours 15 minutes on the traditional boat or roughly an hour on the fast ferry. Walk-on fares are cheap, starting at $11 one way to the Vineyard in 2026, but car space in summer sells out months ahead. After looking at the fares, the booking rules and what the crossing is really like, our verdict is simple: it’s the best (and often the only) way to get a vehicle onto the islands, as long as you plan early and pack a little patience.
What Is the Steamship Authority?
The Steamship Authority is a Massachusetts public agency, created by state law in 1949, that regulates and operates ferry service between the Cape and the islands. Its roots go back to the Nantucket Steamboat Company of 1833, which is why you still hear locals call it “the Steamship” or simply “the SSA.” You can read the full backstory on the Steamship Authority Wikipedia page.
Two things make it different from the private ferry companies you’ll see in Hyannis and Falmouth:
- It’s the only operator allowed to carry cars and trucks to Martha’s Vineyard and Nantucket.
- It runs all year, including the quiet winter months when private boats shut down.
That year-round, car-carrying role is the whole reason it matters. Islanders rely on it for groceries, freight, school trips and medical visits, so the schedule is built around daily life on the islands, not only tourist season.
Steamship Authority Ferry Routes
There are two routes, and it helps to know which one you need before you go near a booking screen.
Woods Hole to Martha’s Vineyard
The Woods Hole Steamship Authority terminal sits at the tip of Falmouth, and it is the busiest ferry port on the Cape. Boats run year-round to Vineyard Haven and seasonally (roughly May to October) to Oak Bluffs. The crossing takes about 45 minutes, which is short enough that you barely have time to finish a coffee and watch the Elizabeth Islands slide by.
If you’re going to the Vineyard with a car, this is your route. There’s no other auto ferry to the island.
Hyannis to Nantucket
The Hyannis terminal on South Street serves Nantucket with two kinds of boats:
- Traditional ferry: carries cars, freight and passengers. About 2 hours 15 minutes.
- High-speed ferry (MV Iyanough): passengers only, about 1 hour, mostly seasonal.
Nantucket is farther out to sea, so the ride is longer and the water can get choppier. If you get seasick, the traditional boat is steadier, while the fast ferry gets it over with sooner. Pick your trade-off.

The Steamship Authority Fleet
The SSA runs a mix of big car ferries, one fast catamaran and a handful of freight boats. The main passenger vessels are:
- MV Island Home (2007) and MV Woods Hole (2016), usually on the Vineyard run
- MV Martha’s Vineyard (1993) and MV Eagle (1987)
- MV Nantucket (1974), the veteran of the group
- MV Iyanough (2007), the high-speed catamaran to Nantucket
The freight fleet (MV Sankaty, MV Governor and the newer MV Barnstable and MV Aquinnah) handles trucks and cargo so the passenger boats don’t get jammed. On the big ferries you’ll find indoor seating, outdoor decks, restrooms and a snack bar. Nothing fancy. The newer boats like the Woods Hole and Island Home feel brighter and more modern, with elevators to every passenger deck.
How Much Does the Steamship Authority Cost?
Here’s the part most people search for. These are the published 2026 one-way fares, which already include town embarkation fees.
| Ticket (one way) | Martha’s Vineyard | Nantucket (traditional) | Nantucket (fast ferry) |
|---|---|---|---|
| Adult | $11.00 | $21.50 | $48.50 |
| Child (5 to 12) | $5.75 | $11.00 | $24.75 |
| Child (4 and under) | Free | Free | Free |
| Bicycle | $5.25 | $8.50 | $8.50 |
A few money notes worth knowing:
- Round trips are simply double the one-way fare. There’s no big discount for booking both ways.
- The fast ferry to Nantucket offers a same-day adult round trip for $69 on Mondays through Thursdays, which is handy for a day trip.
- Tandem bikes and bikes with trailers cost double.
- Pets ride free, as long as they’re leashed or in a carrier.
Car Fares by Season
Bringing a vehicle is where the cost jumps, and it changes with the calendar. For a standard car under 17 feet, one way, 2026:
| Travel period | Martha’s Vineyard | Nantucket |
|---|---|---|
| Jan 5 to Mar 31 | $73.50 | $205.00 |
| Apr 1 to May 14 | $115.50 | $300.00 |
| May 15 to Sep 14 (Mon to Thu) | $127.00 | $320.00 |
| May 15 to Sep 14 (Fri to Sun) | $168.00 | $370.00 |
| Sep 15 to Oct 31 | $127.00 | $320.00 |
| Nov 1 to Dec 31 | $79.00 | $208.00 |
So a summer weekend round trip with a car to Nantucket runs about $740 before you add passengers. That’s a real number. For a short Nantucket stay, most visitors leave the car in Hyannis, walk on, and rent bikes or use the island shuttle.
How to Make Steamship Authority Reservations
Passengers can usually buy a ticket the same day. Cars are a different story. Steamship Authority reservations for vehicles are the single biggest planning hurdle for any island trip.
When Summer Reservations Open
Summer car space goes on sale in one big release every winter. For summer 2026 (travel from May 14 to October 22), the openings were:
- Nantucket: January 27, 2026 at 8 a.m.
- Martha’s Vineyard: February 3, 2026 at 8 a.m.
Island residents get a head start a few weeks earlier. On opening morning the website puts everyone into a virtual waiting room, and popular weekends in July and August can vanish within hours. Dates for summer 2027 are normally announced in January.
Tips for Booking Day
We’ve read enough horror stories to know what separates the people who get their dates from the ones who don’t:
- Create your online account days ahead and test your login.
- Have your vehicle’s year, make, model, plate and exact length ready. Roof boxes and bike racks count toward length.
- Know your backup dates. Midweek sailings are far easier to get.
- Join the wait list if your date is full. It automatically checks every cancellation and books you if space opens, so cancel the request if your plans change or you’ll be charged.
You can also book by phone at (508) 477-8600, daily from 7:30 a.m. to 4 p.m., or by mail.
Changes, Cancellations and Standby
Your first date change is free, and later changes cost $10 each. You can change up to an hour before sailing. For a refund, cancel at least 14 days before departure; closer than that, and no-shows lose the fare.
One big change from years past: vehicle travel on the Woods Hole route is reservation-only all year, since standby was suspended in late 2024. Don’t drive to Woods Hole hoping to squeeze on. The Hyannis to Nantucket route has had its own limited standby program, so check the current rules before counting on it.

Reading the Steamship Authority Schedule
The Steamship Authority schedule changes several times a year, with more sailings in summer and fewer in winter. In peak season, the Vineyard route runs close to hourly from early morning into the night, while Nantucket has fewer but still frequent departures.
Schedules are posted on the official Steamship Authority website, which also has a live “Traveling Today” status page. Check it on the morning you travel. Wind and fog can delay or cancel trips, and Nantucket crossings get hit first when the weather turns because they cross more open water.
Parking at Woods Hole and Hyannis
You can’t park at the Woods Hole terminal itself. Instead, the SSA runs off-site lots with free shuttle buses timed to each sailing.
Woods Hole route lots: Palmer Avenue (Falmouth), Thomas B. Landers (East Falmouth) and Cataumet. In 2026 parking costs $25 a day from April through October and $20 a day in winter. Shuttles carry two bikes on a rack in daylight, though e-bikes won’t fit.
Hyannis lots: the main lot at the terminal plus off-site lots on Lewis Bay Road, Yarmouth Road and Brooks Road. Rates run from $10 a day in deep winter up to $25 in midsummer. Hyannis shuttles don’t carry bikes, so ride to the terminal if you’re bringing one.
Plan to reach the lot at least an hour before your boat in summer. Everyone, with or without a car, must be at the dock 30 minutes before departure, and the shuttle ride plus a line at the ticket window eats time fast.
Our Honest Steamship Authority Review
We’ll keep this simple. The Steamship Authority does its core job well, and it frustrates people in predictable ways.
What We Like
- Low walk-on fares. Eleven dollars to reach Martha’s Vineyard is a bargain by any ferry standard, and a fraction of what private fast ferries charge.
- Frequent sailings. In summer you can almost show up and catch the next boat as a passenger.
- Steady, roomy boats. The big ferries handle rough water well and give you space to walk around on deck.
- Year-round service. When private lines stop for winter, the SSA keeps running.
- Accessible vessels. Most of the main boats have elevators to all passenger decks.
What Could Be Better
- Summer car reservations. The winter booking rush is stressful, and prime weekends disappear quickly.
- Parking logistics. Off-site lots and shuttles add 30 to 45 minutes to your trip.
- Basic food. The snack bar sticks to coffee and simple grab-and-go food. Pack your own if you care about lunch.
- Weather delays. Not the SSA’s fault, but a windy day can scramble your plans, especially to Nantucket.
Verdict: 4.3 out of 5. For car travel, there’s no real alternative, and the operation runs smoothly once you’re aboard. For foot passengers, it’s the cheapest way across. Book early, arrive early, and it’s a pleasant ride.

Steamship Authority vs Other Island Ferries
The SSA isn’t your only option if you’re traveling on foot. A few private companies compete for passengers:
- Hy-Line Cruises runs high-speed and traditional passenger ferries from Hyannis to Nantucket, plus seasonal service to Oak Bluffs.
- Island Queen is a passenger-only boat from Falmouth Harbor to Oak Bluffs in summer, with its own (often cheaper) parking.
- Seastreak runs seasonal fast ferries from New Bedford, and from New York and New Jersey on select dates.
These can be quicker or closer to where you’re staying, but they cost more than the SSA’s traditional boats and none of them carry cars. If you enjoy comparing ferry lines, our Block Island Ferry guide covers a similar New England island crossing, and the Cape May Lewes Ferry review is a good look at another car ferry on the East Coast.
Tips for a Smooth Steamship Authority Trip
- Beat the bridge traffic. Friday afternoons in summer can back up for miles at the Bourne and Sagamore bridges. Leave early or travel midweek.
- Use eFerry digital tickets. You can skip the ticket window line and board with your phone.
- Grab an outside seat early. The best spots on the upper deck fill up fast on summer mornings.
- Layer up. It’s always cooler and windier on the water than on land, even in July.
- Check status before leaving home. A quick look at the Traveling Today page can save you a wasted drive.
- Keep your confirmation handy. Drivers need their reservation and ID at the vehicle check-in booth.

Conclusion
The Steamship Authority is the backbone of travel to Martha’s Vineyard and Nantucket. It’s cheap for walk-on passengers, runs all year, and it’s the only way to take your car across. The trade-offs are the winter scramble for summer vehicle space, off-site parking and the odd weather delay. Get your reservation in the day bookings open, show up an hour early, and grab a spot on the outer deck for the ride. You’ll be on island time before the ferry even docks.
