It’s not uncommon for wealthy couples to sail the Mediterranean in a yacht, but Chris and Regina Catrambone are cruising in a 130-foot ship outfitted especially to rescue migrants at sea. The family was moved last summer by the loss of life among thousands of people fleeing North Africa to find a better life in Europe. In response, they decided to buy a search-and-rescue ship. In their first 60 days, the Catrambones and their crew saved 3,000 lives. The Phoenix redeployed just this month and has run the total up to 4,441.
