According to Florida law, every vessel must carry safety equipment that meets current U.S. Coast Guard requirements for that type and size of boat, and operators are responsible for having it on board, maintained, and ready for use.

In practical, everyday terms, this typically means you must have at least:

  • Personal flotation devices (PFDs / life jackets)
    • One U.S. Coast Guard–approved wearable life jacket for each person on board, correctly sized and in good condition.
* For many motorboats, an additional Type IV throwable device (like a cushion or ring buoy) readily accessible.

* Children under 6 on smaller vessels must wear a PFD while underway.
  • Sound-producing device
    • A horn, whistle, or similar device capable of producing a loud audible signal so you can warn other boats or signal in an emergency.
  • Navigation lights and day shapes (when required)
    • Proper, working navigation lights for night or low-visibility operation, as required by Coast Guard rules and incorporated into Florida law.
  • Fire extinguisher(s) (for most motorboats)
    • One or more U.S. Coast Guard–approved fire extinguishers, number and type depending on vessel length and configuration, kept in serviceable condition.
  • Other Coast Guard–required gear for your class of vessel
    • Florida’s statute essentially says “follow the Coast Guard list” for your boat (for example, some boats also need visual distress signals or ventilation systems, depending on length, fuel, and operating area).

Because the exact list changes with boat size, propulsion, and where you operate, the legal baseline answer to “according to Florida law, what must be aboard a vessel?” is: all U.S. Coast Guard–required safety equipment for that vessel’s class, including at minimum appropriate life jackets, a sound- producing device, required lights, and any mandated fire extinguishers.

Quick Scoop

Florida ties its boating safety rules directly to federal Coast Guard standards, so the safest way to stay compliant is to look up the current Coast Guard requirement chart for your vessel length and type, then treat that as your “must-have on board” checklist.

Mini-Sections

1. Core legal requirement

Florida Statutes section 327.50 says every vessel on Florida waters must carry, store, maintain, and use safety equipment in accordance with current U.S. Coast Guard safety equipment requirements, unless specifically exempted. That effectively makes the Coast Guard list the legal minimum gear list for your boat in Florida.

2. Life jackets: the non‑negotiable

  • A properly fitting, Coast Guard–approved PFD for every person on board is mandatory.
  • Children under 6 must wear a PFD on vessels under 26 feet while underway.
  • Many classes of boats also require a throwable Type IV device immediately available.

A simple way to think of it: no jacket for someone on board = you’re not legally equipped.

3. Sound and lights

  • You must have a horn, whistle, or other loud sound-signaling device aboard every vessel to meet Florida safety expectations and Coast Guard rules.
  • Navigation lights and shapes must be present and working whenever your vessel operates at night or in restricted visibility, following the patterns required by federal regulations.

These items are about letting other boats see and hear you before something goes wrong.

4. Fire and other hazards

  • Most motorboats must carry one or more Coast Guard–approved fire extinguishers, with larger vessels requiring more units or different types.
  • Some vessels must have additional items such as backfire flame arrestors, ventilation systems, or visual distress signals, depending on their size and fuel system.

If you have an enclosed fuel or engine compartment, assume some fire and ventilation equipment is required.

Simple example checklist (typical small Florida motorboat)

For a common 18–24 ft recreational motorboat operating on Florida waters, a reasonable legal setup usually includes:

  • One Coast Guard–approved wearable PFD per person, correct size and condition.
  • One Type IV throwable device.
  • A horn or whistle.
  • Required navigation lights in working order for night use.
  • At least one Coast Guard–approved fire extinguisher (often a B-I type).
