The 70-year-old, only identified as Paccosi, suffered from stomachache and bloody diarrhea at around 1:30 a.m. when the Italian cruise ship Costa Fortuna was on its journey from the southern beach town of Vung Tau to Nha Trang, Tuoi Tre reported.
A maritime rescue center in Nha Trang sent a speedboat to bring him to the shore and he was then rushed to Khanh Hoa Province General Hospital. 
Updates on his condition are not available. 
The same rescue center on April 12 night also helped save a crew member on a Panama ship. The sailor had his hands crushed by a machine and was rushed to hospital.
