Catamaran device made of frameless floats made of profiled sheet filled with polystyrene concrete with internal air compartments made of used autocylinders wrapped in PVC film

摘要

The proposed utility model consists of two floats made of one-piece painted galvanized profiled sheets, without an internal frame (frames). Used autocylinders wrapped in PVC film are installed in the inner cavity of the floats, serving as an air compartment and a stiffener, and filling with polystyrene concrete with a bulk density of up to 150 kg / m3. The floats are connected by steel profiles providing the rigidity of the product, on which two seats are installed. The use of the proposed utility model is advisable for resting on the water and moving through the water using a round mastless sail, oars, and a boat motor.
