Clearly there were a series of mistakes/bad judgement/mechanical and environmental issues that led up to this tragedy.
To make a blanket statement that these need to be banned is a rash and emotional judgement.
Almost every piece of transportation equipment operated outside of the scope of its design can and may fail, that goes for trains, planes, cars, trucks, boats, motorcycles, lawnmowers, tractors etc.
I have been on both DUKW's and once on a ride the ducks boat. The RTD boat was a purpose built for that industry machine that was vastly different than a original DUKW and IMHO would of fared considerably better in rough conditions as they are not a "tub" design like the DUKW.
The original DUKW took a few minutes to convert from land to sea travel and had a bunch of valves and misc. stuff that had to be checked or changed prior to launch.
None of that matters a bit, the main focus needs to be on the families of this tragedy, and the survivors. The industry surely needs to look at why/how this happened and put the checks into place so it doesn't happen again.
I an pasting a blurb I found on the timeline and procedures that happened prior to the sinking.. they did a safety brief and did appear to follow some protocol. From the video of the two boats running side by side it appears that the near shore boat survived because it had just a bit more protection and didnt take as many big waves over the deck.

The NTSB’s initial review findings from the video are below:
- The audio quality varies widely throughout the recording, affecting the intelligibility of what is spoken.
- About 18:27:08. The captain and driver boarded the previously empty vehicle. The driver sat in the driver’s seat and the captain sat in the side-facing seat to the right of the driver. (The captain operates the duck on water and the driver operates duck on the road.)
- About 18:28:00. The crew was told to take the water portion of the tour first, by an individual who briefly stepped onto the rear of the vehicle.
- About 18:29:13. As the passengers were loading, the captain made a verbal reference to looking at the weather radar prior to the trip.
- About 18:33:10. The driver stated a passenger count of 29 and shortly after, the vehicle departed the terminal facility. The captain narrated the tour while the vehicle was in motion.
- Starting about 18:50. In the vicinity of the boat ramp, the captain began a safety briefing regarding the water portion of the tour. The briefing included the location of emergency exits as well as the location of the life jackets. The captain then demonstrated the use of a life jacket and pointed out the location of the life rings. The captain moved into the driver’s seat and the driver moved into the seat directly behind.
- About 18:55:20. The captain announced to the passengers that they would be entering the water. The boat entered the water. The water appeared calm at this time.
- Between about 18:56:22 and 19:00:38. The captain allowed four different children to sit in the driver’s seat, while he observed and assisted.
- About 19:00:25. Whitecaps rapidly appeared on the water and winds increased.
- About 19:00:42. The captain returned to the driver’s seat. The driver lowered both the port and starboard clear plastic side curtains.
- About 19:01:01. The captain made a comment about the storm.
- About 19:03:15. The captain made a handheld radio call, the content of which is currently unintelligible.
- About 19:04:15. An electronic tone associated with the bilge alarm activated.
- About 19:05:21. The captain reached downward with his right hand and the bilge alarm ceases.
- About 19:05:40. The captain made a handheld radio call, the content of which is currently unintelligible.
- In the final minutes of the recording. Water occasionally splashes inside the vehicle’s passenger compartment. (The low frame rate and relatively low resolution make it very difficult to be more precise in the preliminary review.)
- About 19:07:26. An electronic tone associated with the bilge alarm activated.
- 19:08:27. The inward-facing recording ended, while the vehicle was still on the surface of the water.
