Not sure that can be answered. Most mature responsible folks would not go into a very rough sea... My husband was on the beach that day, and said young guys were being beat up by the waves, I believe your supposed to try and swim under a wave, not get clobberd. He heard someone say!!! He came up once and twice but then did not. My husband left, as he was upset watching young people in that water... Only to find out two drowned.. At first they said a woman an boy.. This is mother nature... Never ever try to fool mother nature...
