A vessel's length overall dictates
the equipment the vessel must have to comply with federal and state laws. Length
overall is measured from the tip of the bow in a straight line to the stern of the vessel. Bow sprits; rudders; outboard motors and motor brackets; handles; and other fittings, attachments, and extensions are not included in the measurement.
Length Classes
Some states have laws that refer to vessel lengths as "classes." However,
the U.S. Coast Guard no longer uses these designations to indicate length.
