SeaJets review: SeaJets ferries are often the fastest way to travel between Santorini, Mykonos, Naxos, Crete and Athens, but speed is not the whole ferry experience. Based on my SeaJets ferry ride from Heraklion, the operator is best for travelers who want the shortest sailing time and can tolerate a busy boarding process, aircraft-style seating, higher prices and occasional weather disruption.
The simple verdict: book SeaJets when the timetable saves you meaningful time, especially on a Crete to Santorini ferry or a short island-to-island route. Choose slower ferries such as Blue Star or Minoan Lines when you care more about open decks, comfort, smoother sailing in bad weather or a lower-stress trip to Greece.
SeaJets review: quick verdict for Santorini, Mykonos and Naxos
| Best for | Travelers who want the fastest ferry between Crete, Santorini, Mykonos, Naxos and other Greek islands. |
| Not ideal for | Travelers prone to seasickness, families who want outdoor deck space, or anyone with a tight same-day flight connection. |
| Main advantage | Speed. A high-speed catamaran can cut hours off some routes compared with slower ferries. |
| Main drawback | SeaJets can feel more crowded and less relaxed than a conventional Greek ferry, especially during embarkation and deboarding. |
| Best seat choice | Business class or the VIP lounge on longer trips if the upgrade is reasonably priced. |
| Biggest risk | High wind, meltemi conditions and rough water can trigger delays, timetable changes or cancellation. |
What is SeaJets?
SeaJets is a Greek ferry company built around speed. The fleet includes high-speed catamarans, high-speed monohulls and conventional ferries, with major connections from Piraeus, Rafina, Crete and other ports across the Aegean.
Travelers often type the brand as “Sea Jet” or “Seajet,” but the company uses SeaJets. Its most useful routes are in the Cyclades, especially if you are trying to link Santorini, Mykonos, Naxos, Paros, Milos or Crete without losing a full day to transit.
The key trade-off is simple: SeaJets ferries are fast, but high-speed vessels can be more sensitive to bad weather than bigger conventional ships. The result is a ferry experience that can be excellent on a calm day and frustrating when the Aegean is windy.My experience with SeaJets from Heraklion
My experience with SeaJets started at Heraklion port, where the first impression was not luxury. Embarkation felt busy, loud and compressed, with passengers funneling through the vehicle deck while staff pushed people toward the stairs and seating areas. It worked, but it did not feel relaxed. 
That is the biggest thing to understand before booking SeaJets: the boarding and disembarkation process can feel more like catching a budget flight than settling into a slow ferry ride. You board quickly, find your seat, store your luggage and wait for the crew to get everyone moving.
Once upstairs, the cabin was much better than the boarding process suggested. The business class area had wide seats, large windows, tray spaces and a quieter aircraft-cabin feel. The VIP lounge looked more polished, with private-style seating and a calmer layout than the standard areas.
SeaJets ferry routes: Santorini, Mykonos, Naxos, Piraeus and Crete
SeaJets ferries cover many of the routes travelers actually search for when planning a first trip to Greece. The most important hubs are Athens-area ports such as the Port of Piraeus and Rafina, plus island ports including Santorini, Mykonos, Naxos, Paros, Milos and Heraklion in Crete.
For Santorini, check both the island name and the port name. The Port of Santorini is Athinios, while Thira is the island’s main town and a common name travelers see in booking tools. For Athens from Santorini, Piraeus is usually the main arrival port, not central Athens itself.
| Popular SeaJets route | Why travelers book it | Watch-outs |
|---|---|---|
| Crete to Santorini / Heraklion to Santorini | One of the most practical fast ferry links for a trip to Santorini. | Weather can affect high-speed sailings; avoid tight same-day flight plans. |
| Santorini to Naxos | Useful for island hopping in the Cyclades. | Short route, but boarding and deboarding can still feel hectic in peak season. |
| Santorini to Mykonos | A fast way to connect two headline islands without returning to Athens. | Often expensive compared with slower ferries. |
| Piraeus to Santorini | Works when you want to start from Athens and reach the islands by sea. | Compare against Blue Star if you want open decks and a steadier ride. |
| Rafina to Mykonos or Naxos | Convenient for some Athens airport arrivals. | Rafina is not the same as the Port of Piraeus; check transfer time. |
| Heraklion to Mykonos, Paros or Naxos | Good for linking Crete with the Cyclades. | Multi-stop routes can feel long even on a fast ferry. |
| Milos, Rethymno, Sporades and seasonal routes | Helpful for less obvious island-to-island plans. | Timetable frequency changes heavily by season. |

SeaJets booking, ferry tickets and cancellation policy
You can book SeaJets ferry tickets through the official website, local port offices, travel agencies and ferry comparison platforms. I prefer to compare ferry companies first, then book tickets directly on SeaJets’ website when the price is similar. Direct booking can make it easier to check confirmations, react to timetable changes and handle cancellation questions.
Before booking, check the exact vessel, departure port, arrival port and timetable. A “Santorini ferry” search can show several ferry lines, and the best one depends on your schedule, weather risk and tolerance for a faster but more enclosed ride.
| When you cancel | Typical SeaJets refund rule |
|---|---|
| 14+ days before departure | 100% refund |
| 7–14 days before departure | 75% refund |
| 12 hours to 7 days before departure | 50% refund |
| Less than 12 hours before departure | No refund |
Rules can change by fare type, agency and season, so read the fare conditions before paying. This is especially important if your ferry ride is tied to a hotel check-in, a Sky Express or Olympic Air flight, or a prepaid tour.
SeaJets ferry experience: seats, luggage, food, WiFi and lounge
The SeaJets ferry experience depends heavily on your vessel and seat class. On newer high-speed ferries, the interior can feel clean and modern. On busy summer sailings, the practical annoyances are more noticeable: crowded stairs, packed luggage areas, limited freedom to move around and a sense that everyone is trying to disembark at once.
Embarkation, luggage and baggage storage
SeaJets allows a generous luggage allowance, but baggage storage is still a weak point during busy sailings. Most passengers leave larger bags in racks or designated areas near the vehicle deck, then carry valuables, passports, cameras and laptops upstairs.
My advice: keep anything irreplaceable with you. Do not leave a laptop bag, camera backpack, passport pouch or medication in the shared luggage area. During disembarkation, passengers move quickly, and the crowd around baggage storage can get chaotic.
Business class, VIP lounge and legroom
Business class is the sweet spot if the upgrade price is moderate. The seats feel wider than standard airline-style ferry seats, the cabin is quieter and the windows make the ride feel less boxed in. For longer routes, the extra legroom is worth considering. 
The VIP lounge is more private, but I would not automatically pay for it on every route. For a short Santorini to Naxos ferry, business class or even standard seating may be enough. For a longer Crete to Santorini, Heraklion to Mykonos or Athens from Santorini route, a better seat can change the whole trip.
Food, drinks and WiFi
Onboard food and drink prices are not cheap. From the business class menu I photographed, desserts and snacks such as apple pie, ice cream and jar desserts were around €5.90, Greek yogurt was €6.50 and seasonal fruit was €6.90. The drinks menu showed beer around €5.50–€7.50, local wine by the small glass at €9.90 and full bottles of local wine at €24.90. 
WiFi may be available by voucher on some vessels and classes, but do not build your workday around it. I saw a three-hour WiFi voucher on board, which is fine for casual browsing but not something I would trust for calls, uploads or important business tasks.
Bad weather, meltemi winds and motion sickness
SeaJets runs high-speed vessels, and that speed comes with a weather trade-off. Smaller catamaran-style ferries can feel rough in high wind, Aegean chop or meltemi conditions. If you get seasick easily, this is the section to take seriously.
Motion sickness is most likely when the ferry hits rough water at speed and passengers are seated inside without much access to fresh air. Travelers who are sensitive to sea sickness should bring Dramamine or their preferred motion sickness remedy, choose a larger vessel when possible and avoid heavy food before boarding.
- Book morning sailings when possible, as winds can be calmer earlier in the day.
- Do not schedule a same-day international flight after a ferry that could be delayed or canceled.
- Choose a larger vessel such as a Champion Jet or WorldChampion Jet when the route gives you options.
- Bring water and medication before embarkation rather than relying on the onboard café.
- Watch the weather in the Cyclades, especially in July and August when high wind can affect Greek ferries.
How to choose the best SeaJets ferry: biggest ferry, seat class and timetable
Do not choose only by departure time. The better move is to check the vessel assigned to your route, then decide whether the speed advantage is worth the price. The biggest ferry available on your route will usually be a better choice than a smaller catamaran if you are worried about rough water, seasickness or limited legroom.
When in doubt, choose the first ferry of the day, especially in summer. Earlier departures can give you more room to recover from a delay, and they reduce the risk of a missed hotel transfer, restaurant booking or flight connection later in the day.
For longer routes, business class is often the most practical upgrade. For short island-to-island trips, spend the extra money only if you want a quieter lounge or better seat assignment.
SeaJets vs Blue Star, Minoan Lines and other Greek ferries
The best ferry company in Greece depends on the route. SeaJets usually wins on speed. Blue Star often wins on comfort, outdoor deck space and a steadier conventional ferry experience. Minoan Lines can be better for Crete-focused routes and longer crossings where comfort matters more than shaving off time.
| Ferry company | Best use case | Main strength | Main drawback |
|---|---|---|---|
| SeaJets | Fast island hopping between Santorini, Mykonos, Naxos, Paros, Milos and Crete. | Fastest route options and broad high-speed network. | Higher fares, enclosed seating and more weather sensitivity. |
| Blue Star Ferries | Athens/Piraeus to Santorini, Naxos and other Cyclades routes. | More traditional Greek ferry experience, outdoor decks and often better value. | Slower journey times. |
| Minoan Lines | Crete routes and longer conventional ferry trips. | Comfort, cabins and larger-ship amenities. | Not always the fastest option for island hopping. |
| Golden Star Ferries | Selected Cyclades routes from Rafina and nearby islands. | Useful alternatives on specific timetables. | Coverage varies by season and route. |
For families, the slower boats can be easier because children have more space to move around, parents can step outside and the trip feels less compressed. See our guide to the best Greek islands for families if you are choosing islands around kid-friendly logistics.
Who should book SeaJets ferries?
Book SeaJets if speed is the priority and the ferry timetable helps you avoid a wasted travel day. It is especially useful for travelers with limited time who want to connect Santorini, Mykonos, Naxos, Crete and nearby islands without backtracking through Athens.
- Book SeaJets for short, fast island-to-island routes where the time savings are obvious.
- Book SeaJets when the route is operated by a larger, newer vessel and the weather forecast looks calm.
- Book SeaJets if you value arrival time more than open deck space or a relaxed ferry ride.
Avoid SeaJets, or at least compare slower ferries carefully, if you are seasick easily, traveling with small children, carrying a lot of luggage, connecting to a flight the same day or trying to minimize costs.
Tips for a better SeaJets ferry experience
- Check the vessel, not just the route. A bigger ferry usually gives a better ride than a smaller catamaran in rough water.
- Book early for peak season. Santorini, Mykonos and Naxos routes can become expensive during July and August.
- Arrive early at the port. Give yourself time for port confusion, ticket checks, luggage drop-off and embarkation.
- Keep valuables with you. Shared baggage storage is convenient, but it is not where I would leave electronics or passports.
- Build in a weather buffer. High wind can delay ferry lines across the Greek islands.
- Upgrade selectively. Business class is more worthwhile on longer routes than on quick hops.
- Download confirmations offline. Have your ferry tickets, hotel details and port directions saved before you reach the harbor.
- Do not rely on onboard WiFi. Treat it as a bonus, not a work tool.
- Stand near your luggage before arrival. Deboarding can move quickly, especially when the ferry has several stops.
FAQs
Is SeaJets worth it for Santorini?
Is SeaJets better than Blue Star Ferries?
SeaJets is better for speed. Blue Star is usually better for comfort, deck space, value and a steadier ride in rougher conditions. For Piraeus to Santorini, I would compare both before booking.
Should I book tickets directly on SeaJets’ website?
Yes, when the price is similar. Ferry comparison sites are useful for checking multiple ferry companies, but booking tickets directly on SeaJets’ website can simplify confirmation, rebooking and cancellation questions.
How much luggage can you bring on SeaJets?
SeaJets allows a generous luggage allowance, but the practical issue is storage, not just the rule. Bring bags you can manage yourself, label them clearly and keep valuables with you in the cabin.
Is SeaJets bad for seasickness?
SeaJets can be rough for seasick travelers when the Aegean has high wind or choppy water. If you are prone to motion sickness, choose the largest available vessel, sit near the middle of the ferry, bring Dramamine and avoid booking a high-speed ferry on a windy day when alternatives exist.
Which SeaJets seat class should I choose?
Choose business class for longer routes if the price gap is reasonable. Standard seating is fine for short trips, while the VIP lounge makes the most sense when you want a quieter cabin, better legroom and fewer people around you.
Can you take SeaJets from Athens to Santorini or Mykonos?
Yes, SeaJets operates Athens-area routes from ports such as Piraeus and Rafina, depending on the season and timetable. Always check which port you are using, because Piraeus and Rafina require different transfers from central Athens and Athens Airport.
Final verdict: is SeaJets worth booking?
SeaJets is worth booking when speed is the goal. On the right route, in calm weather, it can make a Greek island itinerary much easier by cutting travel time between Santorini, Mykonos, Naxos, Crete and Athens-area ports.
It is not the most romantic, spacious or relaxing way to cross the Aegean. The boarding process can feel crowded, luggage storage is basic, food and drinks are expensive, and the enclosed high-speed ferry ride is not ideal for anyone prone to seasickness.
My recommendation: use SeaJets strategically. Book it when the timetable saves your day, upgrade for longer routes when the fare makes sense, and leave enough buffer for bad weather. For slower travel, families or couples planning a less hurried route, compare Blue Star, Minoan Lines and other Greek ferries before locking in your tickets.
