Sending Prayers for all involved. :( Unfortunately, the local media and keyboard experts will have a field day with this one. That is a tricky area where the accident occurred. 25 mph speed limit...and beginning of a no wake zone.

May sound stupid but what about a pressure transducer giving constant feedback on tunnel pressure.
I know nobody could react quick enough to stop it but maybe you could see tunnel pressure changes as wind gusts hit as conditions are worsening? As it is now its really hard to tell wind speed and direction when you're traveling 80+ |
It took decades for the Unlimiteds to
start running them. The issue has always been the delay from need to activation. Recent videos show them in action but not sure of their control.

Most folks don't know what ground effect is.
Even computer controlled control surfaces would be dangerous whem on the ragged edge in gusty conditions. Over correction would cause an accident. Difficult to know how much when going that fast. |

Many moons ago I was affiliated with a 7 litre inboard hydro. The hull had what was nicknamed "the toilet". The boat would run around 140 down the straights, as the driver entered the turn he had a pedal that opened a door we'll call it in the sponson(s) which filled it with water to weight the front of the hull down. Come out of the turn, get on the gas, and as the boat felt more comfortable the driver would open another door that would dump all the water, or if it did not feel comfortable he would keep some of it in the sponsons. This was of course a wash, rinse, repeat deal so to speak on a race course. Perhaps a lot different in open water running around? Always thought that was a great idea. Many of the other boats in the class through the years blew over, this one never did.

Very happy to hear that Neal has made a positive turn and was able to be operated on. Please continue to keep him and all affected in your thoughts and prayers.

pretty sure they control those manually with their feet?
Yup. Two pedals. One for the throttle, one for the canard. Thanks. Brad. |

Yup. Literally, just relying on air dump to regulate tunnel pressure at that critical point between loft and lift. Thanks. Brad. |
Pretty sure they started w/sensors mounted to the hull that sent signals to a computer.
Troubke w/that is, it can’t read the water in front of you to set the hull up for it, as we humans can. I looked at the still shots of accident scene and surface of water is clearly wind blown. Water looks choppy too but as I have learned first hand, it’s impossible to judge wave action from pixs or video.
