Take another look at the sentence:
Leaping out of the water onto the safe pier, the sight of a shark scared

Leaping out of the water onto the safe pier, a participle phrase, comes right before sight, an illogical target. A scared young man, not sight, has arms and legs that help with leaping! Before you continue, review the rules for misplaced and dangling modifiers.
