What is the widest boat you can pull on a trailer without a permit?

The widest boat you can typically pull on a trailer without a permit is 8.5 feet (102 inches) in most states in the U.S. This width is consistent with federal guidelines for vehicle and load dimensions. However, it's essential to check local regulations, as some states may have additional restrictions or requirements. Always ensure that your trailer and boat comply with both state and local laws to avoid fines or issues while towing.
