I actually rode a C-8 around Elliott Bay and asked about this since as you say there's lots of logs, or deadheads as my grandpa called them. They said it's not optimal but the logs can be detected and accounted for, and the fins are super strong to impacts from the front. Better to avoid, of course, but they said it would be OK. It just whacks them out of the way basically.
- ttul 3y agoMany logs in the Salish Sea are actually enormous tree trunks complete with root systems…
- specialist 3y agoMy neighbor worked on those hydrofoils. He once told me the foil's spars (?) were made of titanium, which could handle (eg obliterate) sizeable logs. 10" diameter? Edit: Just asked neighbor. He remembers the Pegasus was rated for 18" logs. https://en.wikipedia.org/wiki/USS_Pegasus_(PHM-1) https://en.wikipedia.org/wiki/USS_Pegasus_(PHM-1) Also, the intended top speed proved infeasible, because the foils (wings) would cavitate at high speed, reducing lift. He also worked on Boeing 929 jetfoils. Additional color to the story was a collision with a whale. Gruesome. Big PR mess too. So now no more hydrofoils on the Salish Sea.
