A robust-skin-encapsulated, non-inflatable raft including (1) shape-establishing body structure in the form of an assembly including (a) perimeter structure defining and at least partially circumsurrounding a deck zone, and (b) deck structure joined to said perimeter structure within said deck zone, and (2) an all-over, encapsulating, penetration-barriering and fracture-resistant, elastomeric, polyurea skin coating applied to the assembly of the perimeter and deck structures within the body structure. The perimeter and deck structures are preferably formed of solid foam material. |
