What is one of the leading causes of sportsmen's deaths while boating?

Drowning as a result of falling overboard.

The following leading causes are the reason behind the death of various sportsmen during the boating activity:

1. Not wearing a life jacket: Sportsmen or the skilled swimmers are most likely to ignore this while boating as they trust their skills more. This leads to a fatal mishap.

2. Boat not loaded uniformly: If the weights on one side of the boat do not balance that of the other side, then there is a high chance of the boat flipping over. The boat can trap the person inside it to drown them.

3. Boating in strong current river: Boating in areas with strong currents can increase the chances of the boat flipping over. The strong currents make it hard to swim ashore.

4. Boating in unsafe places: Animal attacks like that of the box jellyfish or the shark can lead to the death of the sportsperson.

The causes vary from location to location but all of them lead to the drowning of the sportsmen.
