What types of tourist submarines are there?

Tourist submarines include deep submersibles (dive depth1over 00m), shallow submersibles (dive depth 10m-50m) and semi-submersible boats (dive depth 1m-2m). In the seawater with a depth of 10 -50 meters, it is the best environment for all kinds of fish and aquatic organisms to inhabit and multiply.

At this depth, the sunshine is abundant and the visibility of seawater is high, which is an ideal place for underwater sightseeing. Because of this, among the tourist submarines built by countries all over the world, shallow water type accounts for the largest proportion and the largest number. The characteristic of semi-submersible tourist submarine is that when it dives into the water, its top is still out of the water. The typical semi-submersible tourist submarine is the "Coral Queen" designed and built by Nemo Company of France. It is 5.9 meters long, 3.9 meters wide and 2.8 meters draught. It can accommodate 5 people and sail underwater for 7 hours continuously. Airbags are installed in the center of the two ballast tanks of Coral Queen, which can prevent the ship from sinking to a greater depth under water and play a role in stabilizing ballast adjustment.
