A pre-fabricated folding structure, in particular a folding boat hull 13, comprises a plurality of profiled panel segments (19, 20, 24, Fig 1B), with juxtaposed edges, conjoined by resilient hinges 37, 38 profiled as continuous edge seals. The structure is configured for overall collapse fold conversion between a 3-D erect state (12, Fig 3A) and a compact stacked flat-pack state (10, Fig 1A). Transverse end seats (46, 47, Fig 5A) at stern and bow may be provided to preserve an erect form and are secured by snap-action, over-centre fasteners (60, Fig 5C). Permanent pliable fabric end wall panels (22, 21, Fig 4A) may be provided at stern and bow and preserve overall flotation and may be buttressed by demountable end wall panels 50 and 54. Storage of ancillary components may be provided in partially-closed internal compartments defined between corresponding facing panels (20, Fig 1B) in-folded about a base panel (19, Fig 1B). |
