New England Boating has a pretty explanatory article:
State launch ramps are open to Rhode Island boaters, except for the ramps at state parks, which remain closed.
Non-residents wishing to work on their boats in RI must self-quarantine while in RI. They must not come in contact with others, and must either stay on their boats or in a residence while in RI. That person DOES NOT have to remain in the state for the 14-day quarantine period, however.
Out-of-state charter boat operators may not enter or do business in Rhode Island.
Out-of-state boaters may enter Rhode Island to remove their boats from the state.
Out-of-state boaters may enter the state to pick up a vessel they have purchased in RI.
Non-resident anglers may not fish in RI freshwater waterbodies.
Transient boaters may not dock or moor at a RI marina.
Anglers entering RI waters by boat may fish in RI marine waters, but may not make landfall in the state.
