Among Florida regulations regarding obstructions to navigation, it is illegal to attach your vessel to a lateral buoy or non-lateral marker (i.e., aids to navigation).

These buoys and markers are considered official aids to navigation, and tying up to them can interfere with their visibility, position, and purpose, creating a hazard for other boaters. By contrast, mooring buoys and docks are specifically intended for securing vessels, so using those is allowed under normal conditions.
