The RV Flip is the only vessel in the world that can move from a horizontal to a vertical position in the middle of the ocean.
Flip is not a small boat, it is about 108 meters long and weighs 700 tons.
Engineers designed it to move vertically at a 90-degree angle, so that the top of the bow is 17 meters high (that is, as high as a five-story building), while the bottom is only 17 meters high. 91 meters long, most of the d.h. ship is underwater. The transformation process takes about 30 minutes and helps to improve the stability and resistance of the ship to wind and waves. It involves pumping seawater into a huge water tank behind the ship, which sinks it into the water and puts the ship in a vertical position. The ship is considered one of the most important ships in the field of marine scientific exploration.
