Starting with the 2008 financial meltdown and continuing through last year’s setback with the Carnival Triumph fire, the headwinds have made profit growth a struggle.

But 2014 could prove to be the breakout year for cruise earnings.

Norwegian Cruise Line Holdings CEO Kevin Sheehan is predicting a 60% rise in earnings before items like interest and depreciation. A Wave season that doesn’t put the industry in an early hole would improve pricing power throughout the year, a boon for agents as well as suppliers.

To be sure, forecasts are more measured at Royal Caribbean Cruises Ltd., and Carnival Corp. isn’t expecting positive year-over-year price comparisons until the second half of 2014.

But if prices do rebound, several factors will be working to keep them moving upward in 2014.

One is the increasing value that suppliers are placing on the travel agent distribution channel. It is likely, for example, that following Carnival Cruise Lines’ Carnival Conversations program, more agents are motivated to sell those ships today than they were a year ago.

Norwegian recently debuted an “Ask Away” monthly video chat with its top sales executives, while Princess Cruises has unveiled a rash of changes in 2013 designed to make selling that line easier.

An energized agent force can only stimulate demand for cruising, which supports improved pricing.

Cruise lines are also being more disciplined about buying new ships, to keep pricing power from eroding. Carnival, for example, is restricting growth to two to three ships a year across its 10-brand fleet. New deliveries scheduled for 2014 include the Costa Diadema, effectively a replacement for the Costa Concordia, and the Regal Princess, a sister to this year’s Royal Princess.

Also taking a sister ship next year will be Norwegian Cruise Line, which is adding the Norwegian Getaway in late January as a Miami-based version of the Norwegian Breakaway.

The most anticipated ship of 2014, however, will be Royal Caribbean International’s Quantum of the Seas, which will debut in the fall in New York. It is a new class for Royal, its first since the two successful Oasis-class giants.

Quantum will include several “wow” elements such as simulated skydiving and a London Eye-style observation capsule.

Another innovation debuting in 2014 will be “virtual balconies,” which are floor-to-ceiling screens on the wall of interior cabins onto which exterior views are projected. The Navigator of the Seas will get some in February in drydock before they are introduced on the Quantum.

Other innovations in 2014 come in itinerary planning, such as the Oceania Cruises world cruise, which debuts at an unheard-of 180-day length.

Below deck, new backup generators and air scrubber devices are being installed on some vessels to make cruises safer and cleaner next year.

On the service side, Carnival Cruise Lines rolls out two new main dining room programs in 2014 that will emphasize American cuisine.

In communications, several lines are upgrading to provide faster Internet access, with the most dramatic speeds promised for the Oasis and Quantum of the Seas, which will access a network of lower-orbiting satellites starting next year.

But not everything is going high-tech. Printed brochures are back at Carnival Cruise Lines in 2014 for the first time in five years.

Next year will be Carnival Corp. CEO Arnold Donald’s first full year at the helm, following his surprise appointment in 2013. Meanwhile, Edie Bornstein takes over as president of Crystal Cruises, and Cunard Line has new leadership, as well.

Two big anniversaries will be celebrated in 2014: The pioneering Queen Mary 2 will be 10 years old next year, and the Panama Canal will turn 100, leading to more interest in canal transits.

Challenges for 2014 will include crowding in the Caribbean, which will get the large MSC Divina and Norwegian Getaway ships as year-round additions to the market, as well as more short itineraries from Princess Cruises.

In Asia, expansions by Princess into Japan and by Royal Caribbean and Costa into China should continue, although the rise in tensions between those two countries might prevent the most desirable itinerary options.

And in Europe, signs of a turnaround in demand in the second half of 2013 could mean a better year in 2014. Although a weak economy in Spain has drained the life from that country’s cruise industry, Pullmantur will further redeploy in 2014 to Latin America, where it appears to be finding a second wind.
