OceanGate CEO Stockton Rush says the company had been evaluating the potential of using a carbon fiber composite hull since 2010, primarily because it permits creation of a pressure vessel that is naturally buoyant and, therefore, would enable OceanGate to forgo the use — and the significant expense — of syntactic foam on its exterior. So, for Cyclops 2 OceanGate decided to avoid the metallic hull altogether and began a search for a manufacturer that could help it develop a composite hull.
Once again the motive for the choice of carbon fibre seems to have been its relative cheapness.
To be fair, I’m sure each trip out there was very expensive to run. They would have costs for the boat, the fuel, the maintenance, and a full crew with specialist skills.

It’s not part of the pressurized system so there’s really nothing to rip it to pieces. Definitely no sign of the carbon fiber parts.

When carbon fiber is the cheap option you know things are getting crazy.
And he still charged $250k…
