Surface Buoys

PR71_1Mooring Systems, Inc. manufactures a wide range of surface buoys designed for use as meteorological and oceanographic instrumentation platforms, using unique designs incorporating  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.

A versatile design approach allows for custom designed towers and instrument mounting for many inshore and offshore applications.
