The U.S. Coast Guard searched into the night Monday for a 41-year-old Delray Beach woman whose new husband says she fell into the ocean after their catamaran struck something early that day in the western Bahamas.

Isabella Hellman is a real estate broker with a 9-month-old daughter, her sister Elizabeth Rodriguez told The Palm Beach Post. Rodriguez said her sister and her husband, Lewis Bennett, were on what was supposed to be a two-week vacation. The Coast Guard confirmed their last place of port was Cuba at about 8 p.m. Sunday.

A Key West-based 154-foot "fast response" cutter out of Key West and a Hercules airplane out of Clearwater were scouring the Atlantic as Monday afternoon turned to evening, Coast Guard spokesman Jonathan Lally said. A second cutter and a sea plane also took part in the search later in the day.

It would be up to the search teams to decide to whether the effort would continue past nightfall, Lally said.

Bennett told authorities he was below deck on the 37-foot catamaran Surf Into Summer, registered in Sydney, Australia, at about 1:30 a.m. Monday when the boat struck an object about 30 miles west of Cay Sal, the westernmost island in the Bahamas.

Bennett, who the Coast Guard said has dual citizenship in Great Britain and Australia, said he came topside to find Hellman gone and the boat taking on water.

Bennett had an emergency transmitter and an E-PIRB emergency positioning beacon and was able to reach the Coast Guard, which dispatched a Miami-based Coast Guard plane to the spot. It found the boat partially sunk and Bennett in a life raft.

Lally said a helicopter was dispatched and a rescue diver descended and lifted Bennett to the chopper, which took him to Marathon in the Middle Keys. He did not know if Bennett required medical attention.

Lally could not say how thoroughly crews were able to search the partially submerged catamaran, or if they were able to locate whatever the vessel might have struck, saying crews were concentrating on the search for Hellman

Cay Sal lies about 100 miles southeast of Key West and about 130 miles east-northeast of Havana. The Royal Bahamas Defence Force told The Post on Monday afternoon that the position is in international waters and that agency has not been called so far to aid in the search.

Hellman was a Realtor with Signature International Real Estate, which specializes in Palm Beach and Broward County and also handles properties in other nations, according to the company’s website.

It was unclear from public documents Monday when or where Hellman and Bennett were married, although photos on their public Facebook pages suggest they have known each since at least 2014.

Hellman’s family said on public Facebook pages that it hailed from Colombia and visited Bogota a few years ago. Hellman and Bennett also visited nations as far away as Japan and London, according to their Facebook pages.
