A fourth family member, an adult man, was reported deceased inside the ship, which the Coast Guard said was "inaccessible" to search and rescue crews.
The Coast Guard -- alongside the U.S. and British Royal Navies -- first launched a search for the vessel after receiving a distress call on Wednesday morning, while Maria was battering the area.
The ship, "Ferrel," reported it was "disabled and adrift" amid 20-foot seas and 100-knot winds near Vieques, an island off Puerto Rico's eastern coast, the Coast Guard said. They later lost contact with the vessel due to the weather.
After a Coast Guard C-130 located the capsized vessel, a Royal Navy rescue chopper was dispatched to assist.
Authorities described the ship as "a research vessel that the family was using as a recreational vessel." Records show the ship was built in 1968.
