Thanks for that Baron.
Would you agree that that's possibly why someone like Mr Rush, who would be well aware of all of he above, refused to allow his admittedly experimental hull design to be classed, rated and certified?
Aerospace and Aeronautical enginners specialise in lightwieght structures Mr Rush did work on F15 program with US Air Force.
Colin Chapman from Lotus Formula One fame built really light cars that failed at times killing drivers.
I can understand why Mr Rush did what he did.
Which classification society was going to certify it you have American Bureau of Shipping (ABS) LLoyds, Veritas to name a few when stuff all if any commercial shipping are built from Carbon Fibre and very little written about it in their specifications?
I know of a few certified passenger boats that were going to be built in Carbon Fibre they didn't use it because the regulations meant skin thickness would have to be much thicker so they went with E Glass to satisfy the rules. The boats turned out much heavier less payload were cheaper they were certified so they could be insured.
Mr Rush had valid concerns with classification societies and carbon fibre they havn't kept up they're a bit outdated with this material.
The ship that took the sub out to Titanic had to be certified with ABS, Lloyds,Veritas etc as it's a commercial ship operating from Canada. The sub was operating in International waters so not required to be certified.
The Factor of Safety was way to low. The first Carbon fibre sub built for Steve Fosset was only meant to be used once to set records then put in a museum.
As the saying goes- Amateur built the Ark Professionals built the Titanic
