What is the purpose of a float plan?

The purpose of a float plan is to provide important information about your boating trip for safety in case of an emergency. It generally includes details such as the boat’s description, the names of the passengers, the itinerary, expected return time, and emergency contacts. By sharing this information with someone who is not part of the trip, you ensure that there is a reference point for search and rescue operations should something go wrong. This is crucial for ensuring the safety of all on board, as it enables authorities or loved ones to initiate appropriate action if you do not return as planned.

The other options do relate to aspects of boating but do not encapsulate the fundamental safety-oriented purpose of a float plan. Planning a travel route, calculating fuel needs, and scheduling maintenance, while all important for boating, do not fulfill the critical function of communicating essential details that could be vital to someone's safety and rescue in an emergency situation.
