A joint construction for a sectional boat arranged to be assembled from a plurality of hull sections, each of the hull sections having a transversely extending edge portion for abutting engagement with the edge portion of an adjacent hull section with flanges on each of the edge portions arranged for mutual overlapping engagement to define a cavity in which an inflatable bladder is disposed whereby inflation of the bladder returns the flanges in the overlapping relationship in the assembled condition of the hull sections to form a leak-proof joint between adjacent hull sections.
