According to the Antique and Classic Boat Society, there are five main classifications of boats based on age.
Historic: Any vessel constructed before and up to 1918.
Antique: Any boat built between 1919 and 1942.
Classic: A boat built between 1943 and 1975.
Late classic: A boat ranging from 1976 to 25 years prior to the current year — from 2021, that would be 1996.
Contemporary: A boat built within the past 25 years.
