Which of the following should NOT be included in a float plan?

A float plan is a document that outlines essential information about a boating trip to ensure the safety of those aboard and facilitate search and rescue efforts if necessary. It typically includes details such as the vessel's description, the itinerary, the number of people on board, emergency contact information, and other relevant conditions.

Including information about fatalities prior to next of kin notification is inappropriate and should not be part of a float plan. This type of information concerns sensitive personal issues and goes beyond the practicalities needed for ensuring safety during a trip. A float plan's purpose is to provide critical logistical and safety data, which helps authorities determine actions in case of emergencies at sea.

In contrast, weather conditions, estimated time of return, and tide information are all pertinent to the safety and planning of a boating excursion. Understanding the weather helps assess potential dangers, estimating the return time supports tracking the trip, and knowing tide information assists in navigation and anchoring decisions. Thus, these elements are crucial for a comprehensive float plan, whereas information regarding fatalities does not contribute to those safety objectives.
