Stefanie's mother, Stacey, sustained serious injuries, while her stepfather Paul Bender and her sister Brooke escaped with cuts and bruises.
Jackson's mother also sent a statement to Channel 3 saying her daughter was a "God-fearing woman".
According to Jackson's family, Maleka was on vacation to celebrate her anniversary with her husband, Tyran Jackson.
The U.S. Coast Guard airlifted four people injured in the explosion to St. Petersburg, Florida Saturday.
Maleka Jackson's father, Malvin Grimes, said she was a loving mother to her 12-year-old son and believed in giving back to her community.
Maleka Grimes Jackson and her husband Tyran were enjoying their time together when an explosion rocked the vessel off the coast of the southern island of Exuma. "I'm a descendant of Wakanda I was here", she said, referring to the fictional African utopia in the movie Black Panther.
A GoFundMe page for the Schaffer family has raised more than $90,000.
Despite the shock and sadness, Maleka and Tiran Jackson's friends say they want the world to know about this wonderful couple.
Chaffer has been in a coma since the accident with a brain injury and has undergone five hours of surgery, including having parts of her legs amputated.
