Clipper and Super Cat are two adjoining moorings on Saxon Reef, and Divers Den notes that its divers navigate the reef wall and offshore bommies here. The name is shared with a pair of moorings on Norman Reef, which confuses some visitors; the two are separate sites on different reefs, and the names presumably date from boats that once used them. At Saxon the site is known for its fish: Divers Den describes different types of anemonefish and a large school of diagonal-banded sweetlips, a friendly green sea turtle that lives on the reef, and the notorious titan triggerfish.

Titans are large, territorial triggerfish that defend their nests aggressively during the breeding season, charging and occasionally biting divers who swim over the nest, so the guide will point out where it lives and divers should swim away horizontally rather than up if challenged. Bottlenose dolphins occasionally appear in the colder months. The wall is covered in hard and soft corals, and the offshore bommies provide shelter for the sweetlips school and for coral trout, cod and moray eels.

Depths are moderate and the conditions usually calm, so it suits Open Water divers, and snorkellers can see the top of the wall and the turtle. The combination of a reliable sweetlips school, a resident turtle and the chance of dolphins makes it one of the more consistently rewarding Saxon moorings. It is often combined with Twin Peaks or Sandra's on the same day.

Visibility is typically 12-20 m, and the sweetlips are usually easiest to find sheltering on the down-current side of the bommies.

Boat access only. Cairns day boats leave from the Reef Fleet Terminal (1 Spence Street) and the neighbouring Marlin Marina on the city waterfront, with check-in between about 7:00 and 8:00 am; most operators run transfers from city and northern-beaches accommodation, and there is paid parking near the terminal. The run of about 55 km out through Trinity Inlet and across the lagoon to Saxon Reef takes around 75 minutes on a fast catamaran and noticeably longer on slower dive boats or into a south-easterly chop.

Clipper and Super Cat are Divers Den moorings on Saxon (Norman Reef has moorings of the same names). Enter from the stern platform.

The prevailing south-east trade winds (typically 15-25 knots from April to September) are what limit Cairns outer-reef diving: above about 25 knots trips may be cancelled, and exposed eastern moorings are used only in light winds. Summer northerlies are gentler but make north-facing moorings choppy. Box jellyfish and Irukandji are present from about November to May (stinger suits on every dive), and the cyclone season runs November to April, when a system in the Coral Sea can close the reef for days.

Visibility drops after heavy rain and strong winds; spring is usually calmest and clearest. Saxon's western lagoons are sheltered; its weather side is dived only in calm conditions. The Saxon Clipper and Super Cat moorings are usable in normal trade winds.

Descend to the wall at 10-15 m, follow it to the offshore bommies and circle them, keeping an eye out for the resident titan triggerfish (give it a wide berth in nesting season). Return along the upper wall and complete the safety stop at 5 m.

Divers Den (Reef Quest, Ocean Quest) – regular; Reef Experience and Down Under Cruise & Dive – occasional; Saxon is also worked by Divers Den, Reef Experience, Down Under Cruise & Dive, Tusa Reef Tours, Aqua Quest and Reef Encounter; the mooring used on any day is chosen by the skipper according to wind, tide and other boats
