The secondhand cruise ship market could pick up steam following recent Cuba restrictions.

With nautical and infrastructure restrictions in Havana, cruise lines calling on the Cuban city have been using older, medium-sized vessels that may not have fit into their traditional fleets.

Industry sources said they expect some pick-up in the secondhand market with Cuba now off limits, as the now less-competitive tonnage could find new owners, or become ships in new ventures.

Among the players, Carnival Corporation sold multiple ships in 2018 but has not announced any transfers or sales thus far in 2019.

Last year, it was announced that the Pacific Eden was sold to Cruise & Maritime Voyages while the Pacific Jewel was sent to Indian start-up Jalesh Cruises.

Holland America Line sold the Prinsendam, which will become the Amera this summer for Phoenix Reisen.

P&O Cruises UK also announced the Oriana will leave the fleet in 2019, joining the Piano Land start up in China.

Royal Caribbean Cruises has not announced any significant fleet changes in some time, nor has Norwegian Cruise Line Holdings.

In December, on an earnings call, Carnival Corp. President and CEO Arnold Donald said that if a ship is earning and relevant, that is most key.
