Aquidneck keeps you in complicance!
We provide and keep track of your town mandated mooring inspections for our customers.

Our divers inspect your entire mooring system without pulling out or dislodging your anchor. We are meticulous in our work. When we do the inspection on your mooring, we use vernier calipers and record our measurement in millimeters. This way we can make our recommendations for future work that may be needed.
We keep diligent records of your tackle to ensure your boat and surrounding boats safety. Moorings are all we do, we are not a marina or dive company. We are a local mooring company that is dedicated to the mooring business.
