Swimming in the sea and open waters is not practically similar to swimming in the pool, as one must recognize and understand the characteristics of the sea water quality and condition in addition to having necessary mastery and skills in swimming. The salinity of the sea water causes painful burning if contacts with the swimmer’s eyes and makes the individual lose the concentration and focus, and incapable of finding his/her path to the shore. If the sea water enters down into the swimmer’s trachea and lungs, it triggers severe coughs to such extent that it practically makes the swimming impossible, and causes complete frustration for the swimmer. The impacts and blows due to the sea waves carry the individual in different directions and therefore cause the swimmer to be drained out of energy and leave him/her exhausted. If the swimmer becomes trapped in such situation, it would be very hard for him/her to get out of that situation and survive. Even with excellent swimming skills and extraordinary physical condition, the sea is yet not safe for swimming as the rip currents are one of the main causes of death among the professional swimmers. Considering such dangerous situations, having a helping means and mechanism seems to be very necessary for the swimmer in order to swim more easily and also to survive and escape the life-threatening situation. The current study and research is towards defining the necessary requirements and specifications of such means and mechanism, and the associated result and outcome will accordingly be applied in design and production.
