Proven profitability and market differentiation. These are the results of tourist submarine operations across the globe. Last year this industry carried over 2 million passengers and enjoyed $150,000,000 in revenue; and the story has just begun. Passenger submarines represent successful, tried and true technology and demonstrated profitability. Since the first contemporary tourist submarine went into operation in 1985, over 45 purpose-built vehicles have entered service worldwide. No longer are trained divers the exclusive visitors to the subsea world. Now, regardless of age or physical ability, people can directly experience the myriad denizens of the deep from the air conditioned comfort of a contemporary 16 passenger submarine.
