A Coast Guard news release says Isabella Hellman was last seen Sunday evening aboard her and her husband's 37-foot catamaran about 30 miles west of Cay Sal, The Bahamas.
The Coast Guard was able to rescue Bennett, who was found floating in a life raft and airlifted to Marathon, Florida.
At about about 1am on Monday, Bennett told authorities that he woke up to the sound of their boat hitting something, according to the Sun Sentinel.
"I saw her before she left and they were going to pick up a boat or something and they have a little baby, and they're a nice couple", said Saragaglia who said she sold Hellmann and her husband Bennett their Delray Beach condo.
He then used a Emergency Position Indicating Radio Beacon (EPIRB) to send a distress signal to rescuers after the catamaran started to take on water.
Schachters said she is a valued employee in Delray Beach and a newly married mom.
Colleagues at Signature International Real Estate, where she is listed as a real estate agent, said they were concerned.
Bennett was found in a life raft but Hellmann could not be found.
"I'm extremely sad to hear about the scary news", owner Ben G. Schachter told the Sun Sentinel.
"I hope that they find her and that she is safe and out of harm's way, and that this nightmare comes to an end quickly", Schachter said.
'Of course everyone here in our firm is keeping her in our thoughts and prayers'.
Those considerations will go into the agency's decision about how much longer to search for Hellmann. Crews were searching by air and by sea for Hellman.
