BRANSON, Mo. - The U.S. Coast Guard has released more information on the duck boat that capsized and sank last month on Table Rock Lake, killing 17 people.

The USCG says that a certificate of inspection was issued in 2017 that did not allow the boat on the water if winds were faster than 35 mph or waves reached higher than 2 feet.

Investigators say that the wind speed was more than 70 mph when the accident happened.

Yesterday the USCG announced it has convened a formal Marine Board of Investigation into the accident.
