She is the namesake of a 47-foot American sailing sloop captained by Nathaniel B. Palmer, who in 1820 became one of the first to view the Antarctic mainland. This modern Hero was built to serve as a mobile platform for the conduct of research in Antarctic Peninsula waters, augmenting the facilities of the U.S. Palmer Station on Anvers Island.
Wood provides resiliency in sea ice and acoustic quiet.
Sails assure steadiness, safety and, again, silence. Her oak hull is sheathed in tough South American greenheart to protect against abrasion by floating ice. Six scientists and a crew of 12 comprised Hero's normal complement, which for special cruises may have been increased by 2 shipboard investigators or 7 transient personnel. Designed primarily for trawling and other biological collecting, Hero has 2 laboratories to support such diverse activities as physical oceanography, bio acoustic studies, onshore geology and biological investigations. The Hero's areas of operation from the spring through the fall were the often stormy waters of the Antarctic Peninsula and the Scotia Sea.
