I would hope that SBI would try to determine what might have happened with Page's crash, at the very least the safety crews involved with the rescue would have useful information.

"How did you calculate the forces on the cockpit? Or did you use the 20 tonnes per square meter as stated by UIM?"

No calculations on the individual panels, but a couple sample pieces were sent to a University to test in England, with a college student studying naval architecture, unfortunately never got any report. In the end it is the combination of all the parts that makes the whole. Wish we could test the whole thing but that is another story, everyone involved made the best choices at the time. The problem is trying to balance safety and performance, if orgs raised minimum weights then we could build the cockpit walls transom strong

Balancing performance and safety is tricky to say the least.

The UIM raised minimum weights 2010 for Class 1 and X-cat to allow for stronger cockpits.

UIM increased weights for 2010, but nothing was mandated and weights were not increased in the USA. Fury races in the US

As I understand the laminating or layers increases the bird strike resistance as compared to a monolithic piece. The problem with polycarbonate as I was told is significantly more deflection observed during impact tests compared to stretched acrylic. Maybe Jim Lee could step in here?

I think the frontal area is a big concern which could be corrected with a thicker wndscreen. There also need to be a age certification. I believe 3-5 years or after an incident the canopy system need sto be recertified.

When the Boat Responsibly (Dragon) was built the 3/4 polycarbonate windscreen was calculated to be able to take a 150mph direct hit. The canopy system was a combination of cabon fiber rollbar and windsceen support with a full chromoly tube cage to protect the occupants front and rear. Similar to Tiger Performance design.

Everyone is talking about cost. When your building a $1 million dollar race boat to go 180mph. What is another $30-$50k. Money is no object when someones life is at risk. Dead is Dead.

I would think the Coast Guard and SBI?

Default Canopy Test for F1 car

https://www.youtube.com/watch?v=e87HIlOIYFA

A test by the FIA Institute to find out what happens when you fire a Formula One wheel and tyre into a jet fighter canopy at 225km/h vs 30mm Polycarbonate canopy.

Interesting to see the difference and how much better the jet fighter canopy does.

You do a water pressure evaluation at 100 MPH ,then one again at 180 MPH your eyes will be opened,Less area is the key here.

I don't know how long it took to reach them, but from the time the boat hit the water until a diver hit the water was 40sec.
