FWIW after seeing a video on youtube I tried swimming in mail armour. It was heavier than Roman mail and covered my arms down to the elbow. It was tiring but I could swim and tread water while wearing it. It seemed no worse than wearing water-soaked winter clothing. IMO if a marine knew how to swim then he could stay afloat no matter what armour he was wearing.
