One American has been confirmed dead in the accident, which came after a flash storm upended the boat before dawn Sunday, spilling dozens of tourists and crew members into the water.
Mexican rescuers were scouring the Gulf of California for seven Americans whose fishing boat capsized two days ago, saying they were extending their search because the missing tourists could still be alive in the warm, calm waters.
One American has been confirmed dead in the accident, which came after a flash storm upended the boat before dawn Sunday, spilling dozens of tourists and crew members into the water. The identity of the dead man was not released.
By early Monday, 19 of the tourists and all 16 crew members had been picked up by the navy or other fishing boats after clinging to coolers, rescue rings and life vests for more than 16 hours.
Mexican Navy, army and state officials met late Monday to discuss the search and there were reports they would call off rescue efforts. But instead they announced the search would continue over an extended area.
Mexican navy Capt. Benjamin Pineda Gomez said that with the warm weather and water temperature in the Gulf of California, it's still possible that the missing tourists are alive.
"A person who casts away can survive many days. That sea is calm," he said.
The 115-foot (35-meter) vessel, the Erik, sank about 60 miles (100 kilometers) south of the port of San Felipe around 2:30 a.m. local time Sunday, the second day of a weeklong fishing trip the group had organized for several years each Independence Day holiday.
The boat capsized less than two miles (three kilometers) from shore, but the navy extended its search 60 miles (100 kilometers) deeper into the gulf later Monday after searching the area by helicopter and airplane and finding nothing, Pineda said.
Most of the 27 men on the fishing excursion are from Northern California and had made the trip before.
She heard about the accident Monday morning from a trip organizer's wife, who told her Dorland, 62, was one of the first people to fall into the water. He wasn't wearing a life vest.
The couple are to be married next month.
Most "were in the water for over 16 hours," said Gibson, who had gone on the fishing trip twice before. "We hope that the information is getting to our families that we are here and that we survived."
"There was an angel sitting on his shoulder," his wife, Murphy Ikegami, said.
Murphy Ikegami said the fishermen made the trip every year but previously would only make day trips out to sea to fish and stayed in coastal hotels at night. This year, she said, they decided they wanted to sleep on the boat.
Those rescued were in good condition with a few scrapes after bobbing in the intense sun and Gulf waters that were about 77 degrees Fahrenheit (25 degres Celsius), according to the Mexican navy. Photos released by the Mexican navy showed several sunburned fishermen in T-shirts and Bermuda shorts waiting to get on a bus.
The Erik has been on the Gulf of California, known in Mexico as the Sea of Cortez, since 1989, according to the website of the company Baja Sportfishing Inc. It was built in Holland and was equipped with stabilizers to handle the turbulent North Sea.
The California Secretary of State website says Baja Sportfishing's business license has been suspended. It doesn't state a reason or give a date.
"We have been working with Mexican Navy authorities and the U.S. Coast Guard in the search and rescue," Baja Sportfishing Inc. said in statement e-mailed to The Associated Press. "Right now our main concern is making sure that everyone is accounted for."
The company would not comment further. It said on its website Monday that all trips have been canceled.
