Answer:
Swim toward the island; the waves aren't going to take you anywhere
Explanation:
A swell in the ocean or in water is a series of waves that are caused by the wind currents across the water surface. It needs a large surface of water to develop a swell. It propagates at the interface between the air and the water surface.
A swell is formed by the wind strength over time and distance.
In the given context, when the ship capsizes because of the swell coming from the northeast direction and there is a island at the southwest direction, I quickly need to swim towards the island because the waves will not carry me to the island instead it will force me deep into the ocean beneath its strong waves. Therefore, I need to swim towards the island as fast as possible.
Hence the answer is ---
Swim toward the island; the waves aren't going to take you anywhere
