MIAMI (CBSMiami) – There’s more trouble at sea for Carnival Cruise Lines. A second Carnival ship is having problems. This time the Carnival Legend is having technical difficulties that are affecting its sailing speed.

In a statement released by the Miami-based cruise company, “the ship’s safety systems and hotel services are all functioning normally.”

The Legend is on the last leg of a seven-day Caribbean cruise that departed Tampa on Sunday, March 10, according to the statement.

“Because of the reduction in speed, its final destination to Grand Cayman was cancelled and the ship will continue to its homeport of Tampa where it’s expected to arrive on Sunday as scheduled.”

Carnival has promised to refund $100 to passengers and give a full refund on pre-purchased shore excursions for Grand Cayman. In addition, guests will receive 50-percent off a future Carnival cruise.

The latest problem at sea for Carnival comes after the Carnival Dream became a nightmare for some passengers Wednesday when power went off and some toilets stopped working while docked at Philipsburg, St. Maarten, in the eastern Caribbean.

The Dream was in St. Maarten on the final stop of a Caribbean cruise when the crew announced it would not be sailing home to Port Canaveral, Florida, because of a mechanical issue with a diesel generator, passengers said.

Carnival Cruise Lines said the Dream had a “technical issue” with its backup emergency diesel generator that was discovered during a test Wednesday. A company statement said that the ship did not lose power but that there were periodic interruptions to elevators and restrooms.

Carnival said all systems were functioning normally Thursday but the company decided to get the passengers home by air.

The Dream was on a seven-day cruise of the Caribbean with 3,646 passengers. The ship’s March 16 voyage from Port Canaveral has been canceled.

Last month, an engine room fire left the Carnival Triumph crippled and adrift in the Gulf of Mexico with more than 4,200 people aboard. That scheduled four-day cruise stretched into eight days as tugs pulled the vessel into port in Alabama. Food was scarce and passengers sweltered in the heat with no air conditioning. People aboard also reported overflowing toilets and human waste running down the walls in some parts of the ship.
