What is an HOV and ROV
In the 1960s, scientists, including naval researchers, developed the first underwater vehicles. These include human-occupied vehicles (HOVs) and crewless vehicles, such as remotely operated vehicles (ROVs) and autonomous underwater vehicles (AUVs).
How long can an ROV stay underwater
Dive length depends on factors like depth and weather, but as long as there are no technical operations, there are no limits on how long an ROV can stay down. On average, dives typically last around eight hours. In comparison, a dive in a human occupied vehicle typically lasts five hours.

Why do divers tape their ankles
This tape, known as ‘k tape’ or kinesiology therapeutic tape, is a special kind of tape used to relieve pain in joints, ligaments and muscles – with divers donning it on areas which can hit the water during dives at high velocity to lessen the chance of swelling and help maintain mobility.

Staying warm is also one of the reasons swimmers and divers use tiny towels called chamois – pronounced “shammy” – at major events. The towels are portable and extremely water absorbent, allowing the divers to dry off quickly and stay warm, Brehmer says. Remaining dry also means safer – and more competitive – dives.
Why do divers towel off before they dive
Diving often involves tucks and pikes, where the diver grips their legs. Wet hands and legs can be slippery, so towelling off before a dive is important. Since Olympic divers sit in a hot tub to keep warm between dives, they’ll towel off and get wet again several times during a competition.
