What does the term "failure to heave" involve according to 18 U.S.C. § 2237?

The term "failure to heave" as defined by 18 U.S.C. § 2237 specifically refers to the act of knowingly failing to obey an order to "heave to" that vessel. This is a significant legal concept because "heave to" is a maritime term that means a vessel should stop or slow down and maintain its position in the water, typically in response to a lawful order from authorities.

Understanding this definition underlines the importance of compliance with maritime law and the authority of officials to issue such commands for safety, security, or navigational reasons. When a vessel does not comply, it can pose risks not only to itself but also to other vessels and the overall maritime environment.

In contrast, the other options present scenarios that do not align with the legal definition of "failure to heave." Refusing to leave the dock during a storm, neglecting to register the vessel, or leaving port without the correct paperwork pertain to different legal obligations or safety concerns, but they do not relate specifically to noncompliance with an order to heave to. Understanding the precise legal terminology and its implications is essential for those in maritime law enforcement and maritime operations.
