Surface Buoy Systems
Mooring Systems, Inc. manufactures a wide range of surface buoys designed for use as meteorological and oceanographic instrumentation platforms.
Above: Model G-2000 surface buoy manufactured by MSI
Above: Watertight compartment end-cap
Our unique designs incorporate durable self-fendering hulls made of Surlyn foam. Surlyn foam is closed cell, extremely tough, and requires little maintenance.
A steel frame and footed base provides a reliable construction that places the buoy system in compression while moored.

A lightweight aluminum tower will support a host of instrumentation, solar panels, and navigation lights.
The central well has a watertight compartment available for mounting batteries or electronics, and a removable topside end-cap allowing access while moored.
