Clipper and Super Cat are two adjacent moorings on Norman Reef that, as Divers Den notes, can be dived as a single site. Both feature swim-throughs for more experienced divers and a shallower canyon that is easily manageable for beginners, and an old glass-bottom boat wreck sits on the wall's southern edge. Parrotfish, angelfish and surgeonfish populate the area.

The names presumably come from tourist vessels, and the wreck is a reminder of Norman's long history as a tourism reef: glass-bottom boats and pontoons have operated here since the 1980s. The wreck is small and broken, lying on the wall rather than on sand, and is now well encrusted and home to fish; it is not a penetration dive, but it adds an unusual element to a reef dive. The swim-throughs are the main attraction for experienced divers, passing through coral buttresses along the wall, while the canyon, a shallower corridor through the reef, gives beginners and snorkellers a sheltered, enclosed route with plenty to see.

Parrotfish, angelfish and surgeonfish are the most obvious residents, joined by reef sharks, turtles, anemonefish, damsels and coral trout. Because the site offers terrain for all levels on one mooring, it is a useful site for mixed groups, and the wreck gives photographers a distinctive subject. Saxon Reef has a separate pair of moorings with the same names, described by Divers Den with a resident turtle, sweetlips and titan triggerfish; that site has its own entry.

Visibility is typically 15-25 m, and the canyon is best dived on the top half of the tide.

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 58 km out through Trinity Inlet and across the lagoon to Norman Reef takes around 82 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 Norman Reef (Saxon 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. Most Norman moorings lie on its protected western side. The moorings are on the sheltered side and are dived in most trade-wind conditions.

Beginners follow the shallower canyon at 5-10 m. Experienced divers descend to the wall, work through the swim-throughs at 12-18 m and head south to find the old glass-bottom boat wreck on the wall's southern edge before returning. Safety stop in the canyon.

Divers Den (Reef Quest, Ocean Quest) – regular; other Norman operators occasionally; Norman is also worked by Divers Den (Ocean Quest liveaboard), Reef Experience, Aqua Quest, Down Under Cruise & Dive, Reef Encounter and Passions of Paradise; the mooring used on any day is chosen by the skipper according to wind, tide and other boats
