R.I. Gen. Laws § 23-9-15: Unauthorized departure from infected vessel.

If any person shall come on shore from on board a vessel as described in this chapter without first obtaining a license, the city or town council may immediately send that offender back on board that vessel, or confine him or her on shore in a convenient place that appears to the city or town council most effectual to prevent the spreading of any infection; and the offending person shall satisfy and pay all charges that shall arise on the confinement, and shall be fined forty dollars ($40.00).
