Ab Dol Ro Zak, 36, a Cham ethnic man, died Sunday at Cho Ray Hospital in HCMC, his family said.
Arrangements for transporting his body to An Giang Province in the delta for the final rites are being made.
Ro Zak was a guide on Hang Chau Tourist Express Boat that was returning with 42 tourists from Cambodia’s Phnom Penh to Chau Doc City in An Giang.
The collision on the Tien River, a branch of the Mekong, last Friday occurred because some barges blocked the boat pilot’s view, according to its owner.
It happened in Chau Doc around a kilometer from the Cambodian border, and two foreign tourists were also injured in the collision.
Ro Zak had his right arm severed and both legs broken.
The tourists, from France and Germany and aged 57 and 67, incurred leg injuries.
All three were taken to HCMC for treatment.
Despite emergency intervention, Ro Zak tragically passed away, leaving behind a wife and a two-year-old daughter.
Fluent in English, Cham and Khmer and working as a guide on tours between Chau Doc and Phnom Penh, he was the primary breadwinner for his family.
Hoang Thi Minh Dang, a company that organizes tours using the Hang Chau vessel, said Saturday the pilot had all the necessary certificates and qualifications for the job, and over 10 years' experience.
Nguyen Khanh Hiep, director of the An Giang Department of Culture, Sports and Tourism, said there would be an assessment of Hang Chau's operations, and any possible violations would be penalized.
