How You Actually Get On and Off Nantucket

Two Ferry Companies, Two Very Different Jobs

Two separate, competing ferry operators run boats between Hyannis on Cape Cod and Nantucket, and mixing them up is one of the easiest planning mistakes to make. The Steamship Authority is the only one of the two that carries vehicles — cars, trucks, and freight all cross with the Steamship Authority or not at all. Hy-Line Cruises, the other operator, is passenger-only: it does not carry vehicles in any form, on any of its boats. If your plan depends on bringing a car, a contractor's truck, or a moving van to the island, Hy-Line is not an option regardless of price or schedule — you book the Steamship Authority, full stop.

Each operator also runs more than one type of boat. The Steamship Authority operates a traditional vehicle-carrying ferry alongside its own faster passenger-only vessel, the MV Iyanough, from Hyannis. Hy-Line runs high-speed passenger catamarans plus a slower traditional passenger boat, also from Hyannis, none of which take cars. In practice that means there are effectively four different Hyannis-Nantucket boat trips to choose from — but only the Steamship Authority's vehicle ferry actually gets a car onto the island.

Vehicle Reservations: A Real Planning Requirement, Not a Formality

Bringing a car to Nantucket is not a walk-up proposition in season. The Steamship Authority runs a formal, named annual booking process — its own materials call it the '2026 Summer Vehicle Reservations Program,' with a dedicated packet and a separate 'reservation tips' page aimed at helping people navigate the opening rush. That framing, plus the existence of tips specifically for surviving the booking rush, points to vehicle slots being a genuinely scarce, allocated resource in peak season rather than something you can count on finding a few days ahead of a trip.

The practical upshot for a buyer or a seasonal owner: if a summer visit, a move, or a project depends on having a specific vehicle on the island on a specific date, that reservation needs to go in well before the trip — treat it the way you'd treat booking a popular flight on a holiday weekend, not the way you'd treat driving onto a bridge. The Vineyard Gazette also reported in October 2025 that the Steamship Authority's board approved fare increases for the 2026 season, so budget for rates to be higher than whatever figure you last saw quoted, and confirm the current number directly before booking (see the gaps below — we could not confirm the exact new dollar figures in this pass).

Freight and Moving Trucks: A Separate System From Passenger Vehicles

Getting a contractor's truck, building materials, or a moving van onto Nantucket runs through the Steamship Authority's freight/truck reservation system, which is a distinct booking process from the passenger-vehicle reservation program described above — it is real and searchable on the operator's own site, but it is not the same queue, the same form, or necessarily the same lead time as booking a family car. Anyone planning a renovation, a new build, or a full household move should ask their contractor or mover specifically how they book freight space and how far ahead they need to reserve it, rather than assuming the passenger-car booking window applies.

We were not able to confirm specific freight fares or required lead times for the truck/freight system in this research pass — that is exactly the kind of concrete cost-and-timing detail a renovation or moving budget needs, so treat it as an open question to settle directly with the Steamship Authority's freight office or your contractor before committing to a schedule, not as a number this page can responsibly supply.

Nantucket Memorial Airport: The Air Alternative

Nantucket Memorial Airport (ACK) is the island's other way on and off, and it's a genuine commercial airport, not just a general-aviation strip — news coverage of a multi-carrier flight-cancellation event at ACK specifically named Cape Air, JetBlue, American Airlines, and Delta among the carriers affected, confirming all four serve the airport. For anyone whose plans don't depend on bringing a vehicle — a closing, a quick weekend, a contractor's site visit, or simply avoiding the ferry-reservation crunch — flying is a real, scheduled alternative rather than a last resort. It does not solve the vehicle problem: a car still has to cross with the Steamship Authority regardless of how its owner gets to the island.

The Town of Nantucket's own site maintains dedicated 'Airlines and Destinations' and 'Arrivals and Departures' pages, which is the right place to check current routes and carriers for a specific trip — schedules and airline lineups at a seasonal airport shift year to year, so confirm directly rather than assuming last summer's carrier list still applies.

Why the Ferry Isn't a Fixed-Time Guarantee

A ferry crossing over open ocean is a different kind of trip than driving across a bridge, and weather is a real, structural part of that difference here, not an occasional inconvenience. Winter nor'easters are a genuine seasonal risk for an island with no land connection at all — a canceled or delayed sailing during a storm is a logical, foreseeable consequence of ferry-only access, and it can affect deliveries, contractor schedules, and even routine errands, not just vacation travel. This page isn't citing a specific named storm or a specific cancellation event for Nantucket, because none was independently confirmed in the research behind this page — treat the risk as a real, qualitative planning factor (build slack into moving and delivery schedules, especially outside summer) rather than a quantified annual cancellation count.

What This Means for Movers, Contractors, and Everyday Deliveries

Put together, the pieces above add up to a genuinely different rhythm than owning on a bridge-connected coastal market. A car, a moving truck, or a contractor's equipment trailer only moves with the Steamship Authority, on a reservation that in peak season behaves like an allocated, book-ahead resource rather than a same-day option. Passengers who don't need a vehicle have more flexibility, since Hy-Line's passenger-only boats and Nantucket Memorial Airport's commercial flights both operate independently of the vehicle-reservation system. And because every one of these routes crosses open water, weather is a real scheduling variable for deliveries and move-in dates, especially outside the summer season.

None of that makes Nantucket impractical to live on or renovate on — thousands of year-round residents and seasonal owners do it every year — but it does mean the ferry and vehicle-reservation calendar deserves the same advance attention as a closing date or a contractor's bid. Before committing to a specific move-in date, a delivery window, or a renovation timeline, confirm the current reservation process, fares, and lead times directly with the Steamship Authority (for vehicles and freight), Hy-Line Cruises (for passenger-only travel), and Nantucket Memorial Airport or the Town of Nantucket's own airport pages (for current air carriers and schedules) — the exact dollar figures and crossing times were not independently confirmed in the research behind this page and should not be assumed from older sources.
