Even when presented with a clear way out of a deadly storm, the sailors refuse to take the easy path at the expense of another man's life. Jonah offers himself up to be thrown into the raging water, but the crew rejects this solution. Instead, they commit to a massive physical effort to save the ship without harming him. They engage in intense, exhausting rowing, an effort that some suggest was already ongoing as they desperately fought the waves [אבן עזרא].
Their goal is to return the ship to dry land, a destination framed as a return since the land is where their journey originally began [רד״ק]. This desperate push toward the shore stems from a few different motives. On a practical level, the sailors hope to simply drop Jonah off at a safe harbor and continue on their way [מצודת דוד]. They might have even planned to tie him up and send him directly to Nineveh so he could complete his mission [אברבנאל]. Beyond these practical ideas, the attempt to reach the shore also serves as a test of God's will. The sailors reason that if Jonah is a servant fleeing from his Master, God would surely want him returned to his homeland. They expect the sea to calm down and allow them to make this return [מלבי״ם].
However, their hopes are quickly dashed. The ship might not have been far out in the deep ocean; it could have been close enough for the sailors to actually see the shore [ביאור שטיינזלץ]. Yet, the forces of nature intentionally work against them. The sea grows increasingly violent, with the winds and waves blowing directly from the land, forcefully pushing the ship away from the shore and back out into the open sea [מצודת דוד, אברבנאל]. Ultimately, this effort fails because God is not interested in a mere technical solution to the problem. Simply returning Jonah to the coast is not enough. God demands that Jonah fully and willingly repent, and since that has not yet happened, the storm continues to rage [מלבי״ם, אברבנאל].
