There is no definitive answer to this question as it varies from country to country. In the United States, for example, rendering assistance to other boaters in distress is not a legal requirement, but it is considered good Samaritan behavior and is generally encouraged. Similarly, in Canada, there is no legal obligation to render assistance, but the Canadian Coast Guard does recommend that boaters help others in need if they are able to do so safely. Ultimately, whether or not you render assistance to another boater in distress is up to you and should be based on your own personal judgment.
