What is the climax of the great wide sea?

In "The Great Wide Sea" by M. H. Herlong, the climax occurs when the three siblings—Ben, Dylan, and their sister—face a life-or-death situation after their boat capsizes during a storm while they are stranded at sea. This intense moment tests their resourcefulness and resilience as they struggle to survive and find a way back home. The emotional stakes are high, as their relationships and individual strengths are put to the ultimate test against the vast and unforgiving ocean.
