The Island of Destiny

You were always a good swimmer. But good enough for this ocean? You gaze out at the blue depths and find that they hold a certain intimidation and each wave that rolls in seems to taunt you to come try and brace it. But then you reason that perhaps you're not that far out from shore though.

You take off your shoes and wade out into the water a little bit. It's actually not that cold. Should you attempt to swim away from this island?
