Overlook Majestic, a Environment War II-classic duck boat was on a typical tour tour with an operator and twenty passengers on board. seven minutes soon after coming into Lake Hamilton, drinking water started off to flood the hull. In considerably less than thirty seconds, the boat sank in 60 feet of drinking water. Just one passenger escaped right before the vehicle submerged but the remaining passengers and the operator were trapped by the vehicle’s canopy roof and drawn less than drinking water. 6 passengers and the operator were capable to escape. The remaining thirteen passengers, which include three small children, missing their life. Investigators examined the boat as perfectly as underwater pictures and video clips and established that inappropriate servicing was the primary result in of the incident.

Soon right before midday on Saturday, May well one, 1999, the amphibious tour boat Overlook Majestic entered Lake Hamilton in close proximity to Hot Springs, Arkansas, on a typical tour tour of the place. On board were twenty passengers and one operator. In accordance to the operator, numerous minutes soon after coming into the drinking water, the vessel outlined to port and then sank rapidly by the stern. The vessel sank beneath the surface area of the drinking water, having the passengers and the operator with it. The vessel sank in 60 feet of drinking water, and thirteen of the twenty passengers, which include three small children, missing their life.
In accordance to testimony from the survivors, the Overlook Majestic had been in the lake only five to seven minutes when its stern grew to become awash inside a minute thereafter, the vessel was swamped with drinking water coming over the stern, and it sank. The Overlook Majestic sank so rapidly that only 7 passengers and the operator were capable to escape from the vessel and swim to the surface area, where by they were rescued by enjoyment boaters in the place.
The survivors’ time estimate of five to seven minutes agrees with the Security Board’s estimates, which are dependent on the vessel’s average pace and the distance that it traveled amongst the entrance ramp and the area of the sinking. DUKWs, these kinds of as the Overlook Majestic, typically trim by the stern when waterborne, ensuing in an aft freeboard of as minimal as eight to twelve inches, depending on the amount, excess weight, and distribution of the passengers.
The Security Board built calculations to simulate the Overlook Majestic incident, in which the boot on the aft end of the aft driveshaft housing had completely slipped off the housing. A detached boot allows drinking water to enter the hull by the annular place amongst the three-inch-diameter driveshaft and the 4-seven/eight-inch-diameter housing.
The Security Board believed that the bare minimum fee of drinking water influx was about one hundred seventy gallons per minute (gpm), which was adequate to do away with the vessel’s freeboard at the stern and sink the vessel in about seven minutes. To confirm the accuracy of its estimates, the Security Board contracted a regarded naval architectural organization to perform in depth calculations. The firm’s preliminary calculations verified that a vessel these kinds of as the Overlook Majestic that was carrying twenty passengers would sink from uncontrolled flooding in as minimal as about 6 minutes.
As at first designed, a DUKW is equipped with a dewatering pump that is chain-pushed from the propeller shaft and driven by the DUKW’s propulsion motor. Operation of the pump, thus, is dependent on the responsible procedure of the vessel’s propulsion technique, as perfectly as the responsible procedure of the pump alone. The Overlook Majestic’s dewatering pump was located to be inoperable, regardless of witness studies that it had functioned only 2 days previously. Reliance on an energetic technique, these kinds of as a dewatering pump, demands confident dependability.
Having said that, even with meticulous servicing and typical screening, dependability can never be guaranteed. Any shortcomings in servicing, no matter if the end result of inadequate instruction or experience, inappropriate or ineffective techniques, failure to recognize a challenge, use of inadequate system, or other causes, can render the energetic technique ineffective.

The useless integrated 3 small children, ages 2 to five, mentioned Sheriff Larry Selig of Garland County. The driver survived.

”The driver informed us that all of a unexpected the entrance started off coming up, practically vertical,” Sheriff Selig mentioned. ”Thirty seconds later, the full point was underwater.”
None of the passengers were donning lifestyle preservers, the Connected Push described. The boat, known as a ”duck” for its use on land and drinking water, sank in just one or two minutes as it cruised considerably less than a mile offshore, mentioned City Supervisor Kent Myers and witnesses.
