You’re looking at a map of the North Atlantic coast and it seems so simple. Portland, Maine sits right there on the jagged edge of New England, and Halifax, Nova Scotia is just across the water to the northeast. Naturally, you’d assume there is a Portland to Halifax ferry that lets you drive your car onto a deck, grab a lobster roll, and wake up in a different country.
It makes sense. People want it.
But here’s the reality: you can’t do it. Not directly, anyway.
If you search for a direct boat connecting these two specific cities, you're going to find a lot of outdated travel blogs and "ghost" schedules from years ago. The maritime history between Maine and Nova Scotia is a messy, complicated saga of shifting subsidies, changing ports, and high-speed catamarans that come and go like the tide. If you’re planning a trip today, you need to understand the "CAT" and why Yarmouth is the name you actually need to know.
The Disappearing Act of the Direct Route
Back in the day—specifically during the era of the MS Scotia Prince—you really could sail straight from Portland to Halifax. It was a long haul, an overnight trek that felt like a mini-cruise. Then things got weird.
The route was canceled. Then it was replaced by the Nova Star, which was a massive, beautiful ship that unfortunately bled money faster than it could burn fuel. By the time Bay Ferries Limited took over the contract with the provincial government of Nova Scotia, the destination shifted.
The Portland to Halifax ferry essentially became the Portland to Yarmouth ferry.
Why? Distance.
Halifax is deep. It’s way up the coast. To get a high-speed ferry from Maine all the way to Halifax harbor, you’d need a vessel that consumes an ungodly amount of diesel, or you'd have to settle for a 12-hour slog. By cutting the trip short at Yarmouth—on the southwestern tip of Nova Scotia—the "CAT" high-speed catamaran can make the crossing in about 3.5 to 5.5 hours.
What Sailing the CAT Actually Feels Like
If you decide to take the current iteration of the Maine-to-Nova Scotia link, you’re departing from Bar Harbor, not Portland.

Wait, what?
Yeah, it changed again. For a few years, the ferry ran out of Portland’s Ocean Gateway terminal. But as of the 2022 season and moving into the mid-2020s, the operation moved back to its "original" home in Bar Harbor. This was a massive blow to Portland foodies but a win for people who wanted a shorter time on the open ocean.
The CAT is a beast. It’s an Alstom-built high-speed catamaran that looks more like a spaceship than a traditional ferry. It’s loud. It’s fast. Honestly, if the seas are even slightly choppy, you’re going to feel it. This isn't a massive stabilizers-heavy cruise ship; it’s a performance vehicle meant to shave hours off a drive through New Brunswick.
Inside, it’s surprisingly posh. You’ve got a cafeteria, a little movie area, and plenty of places to charge your phone. But don't expect a cabin. You aren't sleeping here. You’re sitting in high-back chairs watching the Atlantic blur past at 30+ knots.
The Drive You’re Actually Saving
Some people argue the ferry isn't worth the price. It's expensive. A round trip with a standard SUV and two adults can easily clear $600 to $800 depending on the season and fuel surcharges.
You could drive.
Driving from Portland to Halifax takes about 8 to 9 hours of pure seat time, assuming the border crossing at St. Stephen isn't backed up. You’ll go through Bangor, cross into New Brunswick, and then head down through Moncton. It’s a lot of trees. A lot of trees.
The ferry from Maine to Yarmouth cuts out about 500 miles of driving. Once you roll off the ramp in Yarmouth, you still have a 3-hour drive to get to Halifax. So, even with the ferry, you aren't "in" Halifax yet. You’re just in a much prettier part of the world than the Trans-Canada Highway.
Realities of the Yarmouth to Halifax Trek
Once the CAT drops you off in Yarmouth, the journey to Halifax is actually one of the best drives in North America, provided you don't take the highway.

Most people are tired and just jump on Highway 103. It’s efficient. It’s also boring.
If you have an extra four hours, you take the Lighthouse Route (Route 3). This is where you find the Nova Scotia people see on postcards. You’ll hit places like Shelburne—where they filmed The Scarlet Letter because it looks more like 17th-century New England than New England does. You’ll pass through Lunenburg, a UNESCO World Heritage site with buildings painted colors you didn't know existed.
Then you hit Mahone Bay with its three iconic churches reflecting in the water.
By the time you finally pull into Halifax, you’ve seen the soul of the province. That’s something you missed when the Portland to Halifax ferry was a direct overnight shot. The "new" way forces you to see the coast.
The Economics and Politics (Because it Matters)
You can't talk about this boat without talking about the "subsidy."
Every year, the Nova Scotia government pays millions to keep this link alive. It’s a hot-button political issue in Canada. Critics call it a "money pit" because the ship doesn't always sail full. Supporters point to the millions of dollars American tourists spend in Halifax and the Annapolis Valley.
Because of this political volatility, schedules can change. Ports can change. One year they’re in Portland, the next they’re in Bar Harbor. Before you book a hotel in Portland thinking you’re catching a boat, check the actual departure port for the current season at Bay Ferries.
Essential Planning Details
- Passports: You're crossing an international border. Even though it's a boat, Customs and Border Protection (CBP) on the US side and the CBSA on the Canadian side don't play around.
- Pets: You can bring your dog, but they usually have to stay in the car or in a designated kennel area on the ship. Nova Scotia is incredibly dog-friendly, but the 5-hour crossing can be rough on a nervous pup.
- Fog: The Bay of Fundy and the Gulf of Maine are the fog capitals of the world. It’s common for the ferry to be delayed or for the view to be a total white-out. Bring a book.
- The Season: This isn't a year-round service. It’s a seasonal play, usually running from late May through early October. If you’re looking for a February crossing, you’re out of luck.
The Alternative: The "Short" Way via Saint John
If the Bar Harbor/Portland options are too pricey or the schedule doesn't work, there is another "secret" ferry.
Drive to Eastport, Maine, cross into New Brunswick, and head to the city of Saint John. From there, you can take the MV Fundy Rose across to Digby, Nova Scotia.

This boat is more of a "working" ferry. It carries big rigs and locals. It’s shorter (about 2 hours) and usually cheaper. Plus, you land in Digby, which is famous for its scallops. From Digby, it’s about a 2.5-hour drive to Halifax.
This route is often more reliable and runs year-round. It’s the "pro" move for travelers who want the ferry experience without the "luxury cruise" pricing of the CAT.
Why People Keep Looking for the Portland Connection
Portland is a vibe. Halifax is a vibe. They are sister cities in spirit.
Both have incredible craft beer scenes. Both have working waterfronts that haven't been entirely sanitized for tourists. Both are obsessed with oysters.
The idea of a Portland to Halifax ferry persists because it represents the ultimate Atlantic maritime loop. It’s the dream of leaving a brewery in Maine and waking up at a pub on Argyle Street in Halifax. Even though the "direct" boat is currently a thing of the past, the journey between the two remains the best road trip in the Northeast.
You just have to be okay with a little bit of driving in between.
Actionable Next Steps for Your Trip
To actually pull this trip off without getting stranded or frustrated, follow this checklist.
- Verify the Port: Ensure the ferry is currently running out of Bar Harbor or Portland. As of now, Bar Harbor is the active hub for the high-speed CAT.
- Book the "Flex" Fare: Weather in the North Atlantic is unpredictable. If a storm rolls in, the CAT won't sail. Having a ticket that allows for easy rescheduling is worth the extra $20.
- Check Arriving Requirements: Ensure your ArriveCAN app (or whatever the current Canadian entry requirement is) is updated. Border rules have shifted frequently in the 2020s.
- Plan the Yarmouth Buffer: Don't try to drive to Halifax immediately after getting off the boat. Stay one night in Yarmouth or nearby Argyle. It supports the local economy and prevents you from hitting a deer on Highway 103 at dusk—a very real danger in Nova Scotia.
- Compare Costs: If there are four of you in a van, the ferry is a no-brainer. If you are a solo traveler, it might be cheaper to fly from PWM to YHZ, even with a connection.
The ferry isn't just a commute; it's a transition. By the time you see the Citadel in Halifax, you'll realize the salt air and the slow pace of the South Shore were exactly what you needed to reset.
