Step-by-Step
How to Comply with AIS Requirements in Massachusetts
Follow these steps to stay compliant with Massachusetts's aquatic invasive species regulations:
1
Check Sticker & Inspection Requirements
Massachusetts does not currently require a mandatory AIS sticker or inspection program. However, all boaters are strongly encouraged to follow Clean, Drain, Dry practices.
2
Purchase Your AIS Sticker (If Required)
No paid AIS sticker purchase is required in Massachusetts at this time. Check back annually as state requirements can change.
3
Practice Clean, Drain, Dry
Before leaving any boat launch - and before launching on a new water body - clean all visible aquatic plants and debris from your boat, trailer, and equipment. Drain all water from bilges, livewells, bait buckets, motor, and other water-holding compartments. Allow the boat to dry for at least 5 days before launching on a different water body, or use a high-pressure, hot-water wash.
4
Cooperate with Inspection Stations
Massachusetts operates watercraft inspection stations at launch sites and on roadways. When you encounter an inspection station, stop and allow the inspector to check your boat. Inspections are typically free and quick - usually under 10 minutes. Refusing an inspection can result in a fine.
Noncompliance fine: Fine possible under general environmental protection statutes.
