ABSTRACT:
A flotation device carries two or more people down a waterslide on shaped flotation tubes, coupled by flexible straps into a train. The bows and the sterns of adjacent buoyant bodies are complementarily shaped, preferably the bow being circularly convex and the stern concave as viewed in plan. The straps hold the bow and stern together at a minimal gap, constraining relative rotation by the convex/concave engagement of the bow and stern. In addition, lateral shoulders on the bow abut against the ends of the concave stern to prevent rotation beyond a predetermined angle, for example wherein the bodies in the train are relatively rotated to a bend having about a ten foot radius. This structure provides sufficient flexibility to traverse relatively tight turns in the waterslide course while preventing buckling or accordion-fold collapse when the train of buoyant bodies encounter an obstruction such as a splash down pool.
