好吧,我试着一个答案根据你的澄清。潜水直线在这样一个政权几乎是不可能的,因为看到是阻碍。受过专门训练的自由潜水员可能有更多的机会,但会去几次面。现在假设一个不幸的游泳运动员找到他/她自己的情况和快速分析和描述意识到发生了什么(不太可能)。如果他们是冷血enbough他们可以试着游到一边,然后与周围的流一次或再次向海滩。但是…事情通常不喜欢图画书。有横向(海岸平行)流,海浪和岩石可以很难离开水没有受伤,也许流把外面或者根本不太远。可能有暗潮或打破一波把游泳者在岩石上。外,即使在20°温水的生存几率很低,直到直升机或营救船到达。 And even then, finding a head of a swimmer between the waves is pure luck for the rescue forces. People have actually drowned in the middle of regattas and dense trafic searching for them. That is why it is strictly forbidden to go overboard ;-) There is a reason why people do die in such or similar situations. In any case, the answer to your question is "Yes", a swimmer can easily find himself in a situation where reaching the land is impossible. A snorkler with fins may have better chances. Edit: just so that you know what i am talking about, 3 random videos. [Medium][1] conditions, waves 1-2m. [Dynamic][2] conditions, waves 6-8m. [Calm][3] conditions, .5m waves.
