My 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.
