In practice, spatulas are not used, since they are used from the shore, and there is simply nothing to get to it quickly. This problem can be solved by the TY-3R drone from the Chinese company Didiok Makings, which is widely used by UAVs and rescuers.
The TY-3R uses a main drone that includes an operator with a 720p camera that can survey areas of the water surface in real time. For the purposes of a utopian drone, I approach it and splash down next to it – and it turns into a rescue drone. By the way, its main rotors are covered with special screens so as not to harm the prisoners.

TY-3R can be used simultaneously with an ultra-high speed operator distance of 1.1 km and a maximum speed of 50 km/h. The operating life of the drone is more than 10 minutes without recharging. It weighs less than 5 kg, is completely sealed according to IP68 standard, and can be stored in a glass at a depth of 1 m and underwater until received.
After all, as the operator commands the pilot, this plane was used so that it could take off and land on the water at the base). By this time, TY-3R is already available from the company. $11,803.
