"Mt. Mitchell" also operates two launches, R/V "Mt. Augustine" and R/V "Mt. Shishaldin". For shallow-water surveying, "Mt. Augustine" is a 32-foot (9.75-meter) Silver Streak cuddy-cabin twin-diesel craft outfitted with a multibeam sidescan sonar mount and laboratory space that "Mt. Mitchell" launches and retrieves through a Vestdavit system. "Mt. Shishaldin" is a 25-foot (7.6-meter) landing craft that can seat six people and has a drop-down bow for landing on remote beaches; it can be used for ferrying people between ship and shore, tide gauging, and hauling all-terrain vehicles.
