Transoceanic Cruising: A Practical Guide to Atlantic & Pacific Crossings with Silversea and Ponant
What a Transoceanic Cruise Actually Is — and Who Offers It
A transoceanic cruise is a sustained ocean passage — typically an Atlantic repositioning between Europe and the Caribbean, or a Pacific crossing between North America and Asia — during which passengers spend multiple consecutive days at sea with little or no land in sight. According to Silversea's destination editorial, this format offers a type of travel experience that is essentially unique to ocean cruising: the freedom to be as active or as restful as the voyage demands, day after day, with the horizon as the only constant. In our inventory, transoceanic crossings are operated by two cruise lines: Silversea and Ponant. Together they account for 67 confirmed departures across the calendar, with voyages ranging from 3 to 27 nights. The most common itinerary length in our inventory is 12 nights — long enough to settle into the rhythm of open-ocean sailing while still covering meaningful port calls on either end of the crossing.
Ships, Guest Capacities, and What Size Means at Sea
Travellers considering ship size as a selection criterion will find a meaningful spread across the two operators in our inventory. Silversea deploys several vessels on transoceanic routes: Silver Spirit (608 guests), Silver Ray (728 guests), Silver Moon (596 guests), and Silver Shadow (382 guests). Ponant's transoceanic fleet runs notably smaller: Le Bellot carries 184 guests and Le Boréal carries 264 guests. Ship scale matters on a crossing in ways it does not on a port-intensive itinerary. On a larger vessel such as Silver Ray (728 guests), passengers have access to a broader range of onboard venues, lecture programmes, and dining options to fill consecutive sea days. On a smaller Ponant ship such as Le Bellot (184 guests), the atmosphere is more intimate and the crew-to-guest ratio is proportionally higher — a consideration for travellers who prioritise personal service during long stretches at sea. Neither profile is inherently superior; the right choice depends on how a traveller prefers to spend days when there is no port to disembark into.
Departure Ports, Itinerary Highlights, and Seasonal Patterns
In our inventory, transoceanic departures originate from four embarkation ports: Lisbon, Miami, Vancouver, and Tokyo. Each port anchors a distinct crossing geography. Lisbon-based sailings typically track westward across the Atlantic toward the Caribbean or North America. Miami serves as both an origin and terminus for Atlantic repositioning voyages. Vancouver and Tokyo anchor Pacific crossings, connecting North America with Japan and the broader Asia-Pacific region. Itinerary highlights recorded in our inventory include International Waters (the open-ocean passages themselves), Funchal (Madeira), Mindelo (Cape Verde), Spain, Bridgetown (Barbados), Sitka and Ketchikan (Alaska's Inside Passage approaches), and Hakodate (Japan). This spread reflects the two dominant crossing corridors: the Atlantic arc from southern Europe through the mid-Atlantic islands toward the Caribbean, and the North Pacific arc connecting the Pacific Northwest with Japan. Departures are available across eleven months in our inventory: January, February, March, April, May, June, August, September, October, November, and December. March is the busiest departure month in our inventory — consistent with the industry-wide pattern of spring Atlantic repositioning as ships move from winter Caribbean seasons toward European summer programmes. According to Silversea's destination editorial, Atlantic crossings most typically occur as ships reposition between the Caribbean and Europe, which explains the concentration of March sailings.
Pricing, Inclusions, and the All-Inclusive Cost Framework
Transoceanic cruises on the lines in our inventory are priced on an all-inclusive or near-all-inclusive basis, meaning that the headline fare typically covers accommodation, meals, beverages, gratuities, and a range of onboard programming. This bundled structure is particularly relevant on a crossing, where passengers spend the majority of their voyage onboard rather than in port — making the quality and breadth of onboard inclusions a direct determinant of value. In our inventory, Ponant's transoceanic voyages start from $1,000. Silversea's transoceanic voyages start from $4,000. Prices and availability are subject to change; final price confirmed at booking. Travellers comparing the two lines on price should factor in what is included at each tier. The gap between the two starting prices reflects differences in ship size, service model, and the scope of inclusions. Travellers considering Ponant should verify exactly which services are bundled at the entry fare; travellers considering Silversea should do the same, as all-inclusive definitions vary by voyage and cabin category. One practical note for solo travellers: in our current inventory, there are no departures with at least one cabin offered at no single supplement. Solo travellers should budget for the applicable single supplement when comparing fares.
Physical Demands and Suitability — Setting Realistic Expectations
A transoceanic crossing is not a physically demanding itinerary in the way that an expedition landing or a trekking-based shore excursion would be. The core activity is shipboard life: walking decks, attending lectures or enrichment sessions, using onboard fitness facilities, and dining. Travellers with limited mobility can generally participate fully in a crossing, provided the ship's accessibility features meet their needs — a detail worth confirming directly with the operator before booking. That said, open-ocean passages introduce a variable that port-intensive cruises do not: sustained sea motion. The Atlantic in particular can range from glassy calm to genuinely rough, and no itinerary can guarantee conditions. According to Silversea's destination editorial, the weather on an Atlantic crossing is famously unpredictable — passengers on a Lisbon-to-New York voyage described wondering daily whether the ocean would be ferocious, lake-like, or something in between. Travellers who are susceptible to motion sickness should consult a physician before booking a voyage with a significant number of consecutive sea days, and should review the nights range — 3 to 27 in our inventory — to calibrate how many open-ocean days they are comfortable committing to. For travellers who have not previously done a crossing, a shorter voyage in the 3-to-12-night range offers a lower-commitment entry point. The 12-night length — the most common in our inventory — represents a middle ground that delivers the genuine open-ocean experience without the full commitment of a 27-night passage.
How to Choose: A Decision Framework for Transoceanic Bookings
Travellers considering a transoceanic voyage should work through the following decision points before selecting a departure. **Crossing corridor:** Atlantic crossings (Lisbon or Miami as embarkation) connect Europe and the Caribbean and concentrate in March. Pacific crossings (Vancouver or Tokyo as embarkation) connect North America and Japan and are distributed more broadly across the calendar. The itinerary highlights — Funchal and Mindelo for Atlantic; Sitka, Ketchikan, and Hakodate for Pacific — give a clear sense of what each corridor adds beyond open water. **Voyage length:** In our inventory, voyages run from 3 to 27 nights. Travellers new to crossings should consider starting with a voyage closer to 12 nights (the most common length in our inventory) before committing to a longer passage. Travellers seeking maximum immersion in open-ocean sailing should look at the longer end of the range. **Ship size and atmosphere:** Travellers who want a wide variety of onboard programming and dining options across many sea days should lean toward Silversea's larger vessels — Silver Ray (728 guests) or Silver Spirit (608 guests). Travellers who prefer a quieter, more intimate environment should consider Ponant's Le Bellot (184 guests) or Le Boréal (264 guests). **Budget:** With Ponant starting from $1,000 and Silversea starting from $4,000 in our inventory, the price gap is substantial. Travellers should compare what is included at each starting price, particularly given that onboard spending is the primary expenditure on a crossing. Prices and availability are subject to change; final price confirmed at booking. **Departure timing:** March offers the highest volume of departures in our inventory, which typically means the widest selection of ships, itineraries, and cabin categories. Travellers with flexible schedules who want the most options should prioritise March. Those seeking less-trafficked departures may find better availability in months such as June, August, or November.
