The small naval arresting rope entangler, or SNARE, helps stop boats from evading military & law enforcement inspections by entangling the craft's propellers. SNARE was designed by a team of engineers from NSWC Carderock, NSWC Dahlgren and the U.S. Coast Guard Research and Development Center. "For our part in the project, Carderock engineers designed and built a test bed for evaluating various concepts, developed concepts to test and conducted model scale tests," said project manager Kedric Eisenberg. "Engineers from Dahlgren and the U.S. The system fielded prior to SNARE was the running gear entanglement system, which, according to Eisenberg, worked well as a static barrier, but lost efficiency when launched from a platform. "We designed SNARE to more effectively stop fast boats.
