The moorings are secured using three different-sized helix anchors, each with a 1m extension. They are screwed to a minimum depth of 3m into the substrate. Connected to these are 1" shackles and two sizes of swivels; three of the largest screw anchors have a 1" swivel and the remainder have 3/4" swivels. The lower end of the mooring rope is reinforced with a stainless steel thimble spliced into it. There is a 2m length with a mid-water float ending with a spliced loop. The main mooring lines start and end with sliced loops, the bottom end of which is secured through the mid-water line loop. The mooring buoy is tied off to the main line at the surface leaving 3m remaining as a pick-up line. This section has a float to facilitate locating the line.
