Submersibles Through Time
Johnson Sea-Link (1971)
The Johnson Sea-Link class of highly maneuverable vessels can
accommodate up to four people each in dives of as deep as 3,000
feet, but its chief claim to fame is its use of highly specialized
equipment. Using manipulator arms, suction devices, and rotating
sample-collection tools, the futuristic Sea-Link makes it
possible for crew members to execute from within the submersible
nearly every task once performed by divers. Equipped with sonar,
laser-aimed cameras with arc lights, and a five-foot-wide acrylic
viewing sphere, the Sea-Link is a proven research vessel.
