(CNN) -- Back in September 1522, an 85-ton carrack barely larger than a modern leisure yacht became the first ship to successfully complete a circumnavigation of the globe.
The hazardous journey, which began with a fleet and ended with one lone vessel, saw the deaths of at least 50 crew members, including the original captain.
Juan Sebastian Elcano, who took control after the death of Portuguese explorer Ferdinand Magellan, and his remaining 18 men arrived in Seville, southern Spain, three years after first setting off.
Thankfully, sailing the high seas has become much safer and more comfortable since then, while the allure of sailing around our blue planet remains a travel dream for many.
For those with time and money to spare, cruise operators have come up with a number of offerings to retrace the path of the great sailors of the Age of Discovery.
If you're ready to spend between three and eight months at sea, there have never been more options to complete your very own global circumnavigation.
Travelers now have the option to hop from one ocean to the next in the comfort of some of the most luxurious ships the cruise industry has to offer.
While shorter cruises can vary in terms of clientele, passengers on world cruises tend to be older travelers looking for destination-focused journeys and comfortable shopping at a higher price point.
The ships are decidedly smaller, which means they can make longer stops at destinations, allowing for a more in-depth exploration of some of the world's most picturesque locations.
Another advantage to their size is that they can call at some of the more remote and off-the-beaten-path ports where big ships just wouldn't be able to squeeze.
All of these factors mean that these cruises tend to be aimed at the upper end of the market.
"Many luxury lines have perfected the world cruise concept. You're not on board for the flashy water slides and Broadway-style shows -- you're likely more focused on what's happening in port," explains Colleen McDaniel, editor-in-chief of Cruise Critic, a TripAdvisor-owned publication specializing in the cruise industry.
"That said, a few mainstream lines offer their own world cruises, although those tend to be on their smaller ships.
"Cruises on these lines are somewhat less expensive and are a great option for passengers looking to cruise the world on a smaller budget."
One of the big draws of this type of cruise is its experiential element. This is the ultimate lifetime experience for many.
"World cruises provide an incredible adventure for true travelers at heart. And while cruising is generally a very social form of travel," she adds,"it's even more so on a world cruise, as you're spending far more time with your fellow cruisers -- both on board, and in port. You make friends for life."
In fact, Joseph Chabus, a spokesperson for high-end cruise operator Regent Seven Seas, says there are many cases of passengers meeting on board and choosing to cruise together again.
"We find that guests who frequently sail on our cruises become friends and end up booking world cruises together because they enjoy each other's company and have a shared curiosity to explore our world," says Chabus.
Technology has also helped make the prospect of a long sea voyage more attractive, since it's easier than ever for travelers to stay connected to the office or family back home from virtually anywhere during this absence.
The number of operators launching new products in this space or diversifying their existing offerings has contributed to the growing popularity of this market segment.
Here are 10 of the best around-the-world cruises departing over the next two years:
Cunard
The first continuous circumnavigation cruise was completed by a Cunard ship, the Laconia, in 1922.
Since that voyage, chartered by American Express, the British-American cruise line has sent more ships around the globe than any other cruise operator.
This tradition is maintained to this day with its annual world cruise. The 2020 outing will call at 38 destinations across four continents.
And, from 2021, two Cunard ships will offer full world voyages: the Queen Mary 2 is to sail on the traditional East to West direction, while the Queen Victoria will do so on the westbound route via the Panama Canal.
The World Voyage on Queen Mary 2
Duration: 99 nights
Dates: January 10 to April 18, 2020
Cost: Prices start at around $14,800
Ship: Queen Mary 2
Port of Departure: New York (113 nights) or London (99 nights)
Port of Arrival: New York (113 nights) or London (99 nights)
Crystal Cruises
At the upper end of the market, Crystal Cruises is another veteran of this category, having offered world cruises for more than two decades.
Next up is its 105-day 2020 World Cruise, from Miami to Rome. Although technically not a full circumnavigation, it will travel a good three-quarters around the globe.
Further editions of this luxurious cruise, 2021 and 2022 -- the latter a full circumnavigation of the world starting and ending in Miami -- are already on the market.
If these journeys sounds too long, passengers can book one segment of the route and complete the other part of the itinerary by air.
Crystal Cruises 2020 World Cruise
Duration: 105 days
Dates: Jan. 6 to Apr 21, 2020
Cost: Prices start at $194,000
Ship: Crystal Serenity
Port of Departure: Miami

Silversea
Boutique cruise operator Silversea has two different offerings in this segment -- a more traditional cruise on board the Silver Whisper, a ship designed for around 500 passengers, and an active cruise aimed at more adventurous travelers.
The latter will be operated by the Silver Cloud, a relatively small ship with a 250-passenger capacity and a strengthened hull allowing it to venture into polar waters that are off limits to most other ships.
This cruise travels from Antarctica all the way to the Arctic Circle by way of the Pacific and Indian Oceans.
Duration: 150 days
Dates: Jan. 7 to June 6, 2021
Cost: Prices start at £51,000 ($61,700)

Ship: Silver Cloud
Port of Departure: Ushuaia, Argentina
Port of Arrival: Tromso, Norway
Seabourn
Another boutique operator at the high end of the market, Seabourn has brought back its world cruise after a six-year hiatus.
Although this isn't a full circumnavigation, it gets very close.
Passengers depart Miami in an eastward direction and cross the Atlantic, Mediterranean, Red Sea, Indian Ocean and Pacific Ocean before disembarking in San Francisco, California.
In a way, it's a US coast-to-coast sailing, but with a bit of a detour.
Duration: 146 nights
Dates: Jan. 4 to May 28, 2020
Cost: From $66,999 per person (rates are based on double occupancy and are subject to change)
Ship: Seabourn Sojourn
Port of Departure: Miami
Port of Arrival: San Francisco
Viking Cruises
Also at the high end of the market, Viking has brought its signature Scandinavian-chic to longdistance cruising.
This is the longest world cruise currently offered, taking a total of 245 nights, or about eight months at sea.
Duration: 245 nights
Dates: Aug. 31, 2019 to May 2, 2020
Cost: Prices start at £82,990 ($99,350)
Ship: Viking Sun
Port of Departure: London
Port of Arrival: London
The 2019 trip is already underway, but there are still variants of the cruise available.
For example, the 161-night Miami to Londonsegment (setting off December 14) and the 119-night Los Angeles to London(departs January 4) portion of the itinerary are marketed separately.
If nothing less than the full experience will do, contact Viking directly if you want a spot on the next epic sailing.
Regent Cruises
Regent has been offering luxury world cruises for quite a few years.
Its next one is the 131-night 2020 cruise. It starts in Miami, then goes west across the Panama Canal and the Pacific, up the Indian Ocean and the Mediterranean, then returns to Miami.
At 117 nights, the 2021 edition is a little shorter. It follows a similar route, but stops in Barcelona instead of going all the way to Miami.
The 2022 edition will be focusing on the Pacific, with a 120-night circumnavigation, not of the whole globe, but of its largest ocean.
This choice has proven popular, though. The day it was launched, in July 2019, this four-month Pacific cruise beat the Regent's same-day sales record for this type of product by no less than 39%.
Duration: 131 nights
Dates: Jan. 6, 2020 (or January 24 if boarding in San Francisco) to May 17, 2020
Cost: Prices start at around $66,700
Ship: Seven Seas Mariner
Port of Departure: Miami
Port of Arrival: Miami
MSC
MSC joined the fray in 2019 with its first ever circumnavigation cruise, departing from Genoa, Italy, on MSC Magnifica and returning to the same city 119 days and 49 stopoff destinations later.
During this voyage, which sold out years in advance, the ship will sail around the world in a westward direction.
The European cruise operator has since launched its next two world cruises, also departing from Italy, but following slightly different itineraries.
MSC Around the World Cruise 2020
Duration: 117 nights

Start date: Jan. 5 to May 3, 2021
Cost: Prices start at around $15,000
Ship: MSC Poesia

Oceania Cruises
The number of places visited by Oceania's Insignia on its six-month world cruise is one of its strongest selling points -- no fewer than 100 ports in 44 different countries on all six continents.
Duration: 180 or 200 days
Dates: Jan. 8 to July 5, 2020
Cost: Prices start at around $43,300

Its 2021 World Cruise features 50 destinations in 32 countries and six continents, with the ship sailing in a westward direction.
Passengers are given the choice of embarking or disembarking either in Florida or in California.

More than 60,000 people have sailed around the globe on Costa Cruises' ships since 2011, when the Italian operator started offering the product on an annual basis.
The upcoming edition of the cruise, departing Venice in January 2020, is already sold out.
The 2021 edition, which departs from Savona, Italy, instead of a global circumnavigation, is to focus on Africa and America.
Duration: 113 days
