How to deal with vortex

Non-boats rush through the vortex with great inertia, otherwise the curled waves will crash back into the boat and stop it. The water will immediately fill the tank, often causing the ship to rotate violently and even tilt. Some whirlpools may even lift the boat. Of course, this is not very common because the boat will be aggravated by soaking. At this time, the crew should immediately enter the downstream flow of water to avoid possible overturning. The measure is to use paddles or rakes to move the water downstream to escape from the vortex. Although the water in the whirlpool surface is usually countercurrent, it is actually There is water on the lower level and the side of the whirlpool. It is a last resort. You can use the rope on the shore to pull the boat out of the vortex.

Overturning--The overturning is caused by such things as large whirlpools, waves, unilateral waves and obstacles (such as stones and fallen dead trees). Then the objects of the ambulance are in order of priority: 1. Your own 2 , other occupants on board 3, equipment

Try to jump open to avoid hitting the obstacles. If you are sure not to fall into the back flow between the ship and the stone, you should float on the water as much as possible, and you can also go ashore to avoid the rapids. Try to keep up with your peers. If someone is missing, check the boat to see if he is trapped by rope or clothing (this is why it is necessary to make sure there are no loose straps); don't worry about the equipment, and the first thing is to identify each Crew safety. As it is very difficult to navigate from the overturned boat to the shore, you will usually need the help of other ships. This should be done on a calm surface away from the rapids. The rescue ship is approaching the water, picking up a cable from the overturning vessel, and then carrying it to the shore. The remaining vessels should also rescue the drowning people along the way and count the number of people as fast as possible.

Beaching - rapids and falls are unavoidable. Attach a lifeline in an unoccupied rapids area to help the boat pass and keep close control of the boat on the shore, remembering not to put a rope on yourself. Tying a knot on a rope or winding a rope around a tree can help you achieve control over the boat. Bring everything on the beach.
