submarine yacht simulate mother nature

No long distance surface swimming animal exists. Nature eliminated this concept probably for good reasons. The most obvious is the cost of locomotion. Studies suggest that there is a factor 5 in energy cost for locomotion between surface swimming and submerged locomotion . Therefore whales swim below surface. At ( concretesubmarine.com ) we suggest to close in to the whale model in yacht building. We are aware that this concept might be percieved as "revolutionary" but the idea of submarine tankers has been around for a while now. One of the main reasons why it has not been realized until now is that ships are part of a larger sistem that includes harbors and slip instalations, tecnical ruling, cost of insurance, and others that create disadvantages that would outweight the advantage of less cost of locomotion. So submarine ships will have to wait. On the other hand a private yacht the owner can implement what he considers the right thing to do. So submarine yachts will first arrive as private boats in yachting segment. Concretesubmarine.com is dedicated to give the private yacht owner one single item in hand - a yacht hull that can submerge.
We tested it for decades, it workes perfectly. It is even better - the overall cost of building and operation of a submarine yacht as we suggest is significantly lower than the cost of a surface yacht of similar size.
