A vehicle, adapted for travel over water, having floats and strong, light-weight walls including preferably porous material tie-beams or other tie-members and pipes that are attached to the tie-members, having sealed bottom ends in the floats, and sealingly joined elsewhere by elbow and tee fittings. Preferably, the pipes are of rigid or semi-rigid plastic, but optionally they may be of thin metal or resilient plastic and optionally inflated with gaseous material. Every other horizontal pipe of the lower-deck frame that is above the under-structure float is joined at its ends by elbows to an upright tube of the float frame; and every other deck pipe that is above the float is joined to a cabin-sidewall tube. This junction between an alternate lower-deck tube and each sidewall pipe may be by a tee fitting, in which both a sidewall tube and a float tube may be fitted, or optionally by an elbow with no float tube at this point. Each tube of a sidewall is joined in a cabin-framework member to: a pipe of the lower deck; a pipe of the cabin-top upper deck; and a pipe of the opposite sidewall. Exterior and interior skins are fixed to the tie-beams or the like, preferably including metal mesh, preferably nailed or screwed to porous-material beams, and stucco of cement (Portland, epoxy or other cement) and aggregate, troweled or sprayed on the mesh. Between the exterior and interior skins in-situ-placed foamed plastic preferably imbeds the pipes.
