In case your boat turns, it is fundamental to ask for help and it is only possible to untap with the help of another larger vessel. It is necessary to tie ropes in the overturned boat, to use all the human force possible, and if there is, the hydraulic bridge can also help a lot. After un-knocking, the boat must be towed, as the engine will often not start again.
Also, you should take some precautions to avoid getting hurt. Among these precautions, you should float upstream of your craft, preventing you from being crushed. It is also important that you float with your belly up, feet and hands stretched out and in the same direction as the current. You should never float against the current or stand in the water.
