Search for missing man to resume Sunday after yacht sinks in Lake Michigan near 31st Street Harbor

A search on Lake Michigan for a missing boater was postponed Saturday due to dangerous water conditions.

The U.S. Coast Guard said they received calls about a 25-foot double-decker pleasure yacht capsizing and then sinking around 7:30 p.m. Friday near the 31st Street Harbor.

Rescue crews are waiting until Sunday to resume their search. The conditions have been too choppy on the water Saturday, and that's why the search had to be suspended.

The Coast Guard said 16 people were on the boat at the time of the incident. All but one of those people made it out of the water.

Three people, a man and two women, were taken to a local hospital for treatment after the incident, all in good condition, police said.

A witness said he saw the boat speeding in the water before flipping over, and then he heard screams for help.

The US Coast Guard and CPD are searching for at least 1 person still missing after a pleasure yacht sank in Lake Michigan near 31st Street Harbor.

A group called Boat Safe Chicago captured drone video of the wreckage just moments after the crash. Jon Meyer with the group was on their boat nearby, enjoying a concert at Northerly Island when the mayday call came in.

"We were the closest boat to it, so we came around the corner... saw the victims in the water... saw them getting helped," Meyer said. "There were a couple other boaters there also helping."

Meyer said there may have been some warning signs ahead of the accident.

"So when they actually turned to go into the harbor, the boat flipped over... several of the passengers had warned the captain hey the boat has a strange lean to it... so it looks like it was taking on water," Meyer said.

In a separate incident, police said a 36-year-old man was pulled from the lake at around 4:32 a.m. Saturday. ABC7 was at 31st Street Harbor as paramedics rushed the person into an ambulance and began to perform CPR.

The man was taken to University of Chicago Hospital where he later died.

The circumstances surrounding the incident are still being investigated, according to police.

It's not clear what time rescue crews will resume the search Sunday. They will see how conditions are on the water in the morning.
