Exempt vessels, which aren’t required to get documentation, are those that are not used for commercial purposes. This applies to vessels of all sizes. A lot of people think that if a certain commercial vessel falls under a certain gross tonnage, then it doesn’t have to be registered. However, this isn’t quite right. There is a specific type of registration meant for small vessels, which you can find under the respective category here on the National Vessel Registry Center Corp website. If your vessel is used for leisure purposes, then it doesn’t have to be registered. In those cases, you can look instead into the pleasure craft licence process.
