A private submarine that can provide the owner with the same kind of independence, living space, autonomy, and long range capacity as a yacht.
With a additional capacity to submerge in case of bad weather and cruise under snorkel to avoid movements by waves for a much smoother travel and ocean living experience.
At concretesubmarine.com we are going for "leave coffee cup on table" conditions even in severe storms with 7 m wave heigth for a small submarine yacht of 18m (200ton) running under diesel at snorkel depth.
