The Long Bay reef is located at 360 40 52 S, 1740 45 14.8 E in 5.5 m at minimum spring low tides. It comprises twelve concrete hemispherical shells made of 60 MPa concrete with microsilca added. There are nine Bay Balls [mass approximately 300 kg, height 0.7 m, base diameter 1.0 m with about 10 piercing] in a N S line. At the Northern end, there is a Pallet Ball [mass approximately 1200 kg height 0.9 m; base diameter 1.2m with about 15 piercing]. ]. At the Southern end, there are two further Pallet Balls; one with a 30x30 cm slate plate attached to a vertical surface and the other with a plate attached to close the top hole of the unit; i.e. in a horizontal position.

Octagon Reef at 360 40 51.1 S, 1740 45 19.6 E This also comprises twelve units with four of the smaller Bay Ball units planted as the central core. There are four Bay Balls around the perimeter; a Pallet Ball at the Eastern point of the octagon; and one further Pallet Ball on the Southern margin. There are slate plates attached to a vertical surface of both these Pallet Balls. Another Pallet Ball is placed on the western side. The last Pallet Ball forms a tail to the south since inclement weather prevented it being placed in geometrical perfection. All the spacing is again about 1.0 meter.
