摘要

Improvements in the manufacture of reversible rigid rafts for the rescue of castaways, of the type comprising a closed contour float of any geometrical configuration, filled with a cellular material of closed cells such as solidified polyurethane foam or another of great buoyancy, with or without hollow transversal half bridge subdivided into several compartments, fitted with hermetically sealed hatches on the upper and lower tuestes, adapted to store food, drinking water, fishing tools and others, characterized by the space of the raft contoured by said float and intended to be occupied by the shipwrecked, is provided with two bottoms, placing one of them in the lower part and the other of them in the upper part of said space, symmetrically with respect to the horizontal midplane of said float, so that in the raft thrown into the water, fall as it falls, any one of these funds can constitute the The raft itself can be occupied immediately by the castaways just by cutting the other of these funds, which has remained above, thus making the space for the shipwrecked in a depth corresponding to the total height of the float.
