The two base types of modules of Lifebuoy—one in a rectangular shape and the other in an “A” shape—can be combined and separated easily to create an efficient system of lifeboats. Link up to four sections to create one large boat to accommodate four people. Or use each base separately for individual boats. Each boat can be turned into a life buoy with the simple pull of an emergency handle on the bottom of the boat.Designed by: Chunmao Wu, Renqiu Chen and Xiang Wu of Donghua UniversityContact: Chunmao Wu
