Hardly a week goes by without an announcement by someone in the cruise industry of a charitable endeavor or donation.

Recently I was at a lunch on a cruise ship at the Port of Miami, where Azamara Club Cruises presented a $4,000 check to the head of one of the big travel agency networks, who is trying to raise $125,000 for the Leukemia and Lymphoma Society.

A week earlier, Carnival Corp. and the Carnival Foundation gave $200,000 to Create Common Good, an innovative job training program.

And millions have been raised across the industry this year for Typhoon Haiyan relief in the Philippines.

One of the biggest cruise-connected projects I have heard of, however, is the push to build an entire ship for medical care and training in Africa.

Mercy Ships, a 35-year-old charity, is raising funds for its first purpose-built hospital ship. It announced a contract at Cruise Shipping Miami with the China Shipbuilding Industry Corp. for a 36,600-gross-ton ship to be delivered in mid-2017. Plans call for the ship to be built at the Tianjin Xinang Shipyard.

Donald Stephens, founder and president of Mercy Ships, wouldn’t reveal the exact budget, but said it is more than the $75 million spent to convert and retrofit a cargo ship or ferry, such as the Africa Mercy, the latest of four ships the organization has operated.

With a purpose-built ship, Stephens said his group can deliver more beds, more and better operating rooms and improved training for medical personnel in the African countries where it mainly operates.

“You can design the ship to the hospital, rather than design the hospital around the ship,” he said.

Mercy Ships is in what Stephens said is a “quiet phase” of fundraising, where it is pursuing big-money donors to build momentum. It will soon begin seeking smaller contributions from individuals, he said.

One big gift has come from bond king Bill Gross and his wife, Sue, who contributed $20 million to match a gift of identical size from an anonymous donor.

Gross is the founder of Pimco, which runs the largest bond fund in the U.S. and has $1.9 trillion of assets under management.

Among the services delivered by the existing ship is maxillofacial reconstruction and tumor removal surgery. A three-minute video of various deformities and defects treated by Mercy Ships makes a compelling case for the need for action.

“Our goal with this [ship] is to more than double the hope and healing through life-changing surgeries provided to those with little access to specialized health care,” Stephens said, “and to increase the partnership of training and educational support of health professionals within the developing nations our ships will continue to serve.”
