A gorgeous late 1960s cutaway from Pierre Mion for the “Deep Diver,” a ferry submarine designed by Edwin A. Link and built by Perry Submarine Builders, Riviera Beach, FL.
This 22-foot, 4-man craft was meant for work, not play–underwater construction or research.
Interestingly, Perry Submarines is still around and making submersibles, one of which is going for $695,000!
