A tourist submarine is a vehicle designed to take passengers on visits of the underwater realm.
Tourist submarines offer passengers the opportunity to explore and enjoy underwater fauna, flora and seabed features, including shipwrecks.
Tourist submarines usually have large glass observation domes or windows to enhance exterior visibility. Design and materials will determine the maximum working depth of each submarine.
Choice will depend primarily on passenger capacity and maximum working depth of the submarine. These factors vary inversely, since increased depth requires reduction in glass surface due to increased ambient pressure.
