What is the climax in the novel The Cay?

I suppose it could be argued that there are two possible
climaxes in Theodore Taylor's novel, The Cay. The most obvious
would be when Phillip is rescued from his long stay on the island and is eventually
reunited with his parents. It serves to complete the story of his castaway stay on the
island; however, it is not a typically climactic scene--in fact it seems somewhat
anti-climactic following the suspenseful buildup that occurs when the hurricane hits the
island and results in Timothy's death. The hurricane and the death of Timothy is
certainly the highest peak of action in the novel, but since Phillip's life continues
for a while longer, his rescue would probably be a more logical
choice.
