Brothers, Daedalus & St John's
Brothers, Daedalus, and St John's are the Egyptian Red Sea stripped to essentials: tiny reefs and islands far offshore, reachable only by liveaboard, where walls plunge from lighthouse islets straight into shark water. The Brothers add two historic wrecks draped in soft coral; Daedalus stacks scalloped hammerheads off its northern point; St John's spreads caverns and pinnacles near the Sudanese border. This is Egypt's big-animal circuit.

Isolation does the work. Big Brother is a 400-meter sliver of rock under a Victorian lighthouse, and its walls carry the traffic of open sea: grey reef sharks on the plateaus, oceanic whitetips under the boats in fall, thresher sharks rising from the thermocline at first light. The Numidia and Aida, wrecked against the island a half-century apart, have become vertical gardens of soft coral. Daedalus, some 90 kilometers off Marsa Alam, is the most reliable scalloped hammerhead station in Egyptian water from late spring through summer, with an anemone field on its north point that ripples like weather. The St John's group softens the itinerary with sunlit cavern mazes and gorgonian-hung walls. Seas are open, currents honest, and schedules long - most boats ask for advanced certification and a meaningful logbook before they take you.

Liveaboards run most of the year, but winter crossings can be rough and departures thin out. Hammerheads school at Daedalus roughly May-August; oceanic whitetips concentrate at the Brothers and Daedalus in October-November.

アクセスと宿泊
アクセス: Book the boat first; almost all guests fly into Marsa Alam or Hurghada and transfer to the marina the same evening.
宿泊先: Accommodation is the boat. A marina-hotel night in Port Ghalib before or after the cruise smooths flight timing.
リブアボード: Seven-night itineraries from Port Ghalib or Hurghada are standard, often labeled BDE (Brothers-Daedalus-Elphinstone) or Deep South for the St John's reefs.
費用: Liveaboard-only - no day boats reach these reefs. Budget for marine-park fees on top of charter rates; seven-night itineraries are the norm.
ダイビングの合間に: Effectively none once aboard - reading, surface intervals, and a lighthouse visit at Big Brother or Daedalus when landings are permitted.
安全性と実用情報
危険生物・リスク: Strong, shifting currents; blue-water descents and ascents; distance from help measured in hours; oceanic whitetips demand disciplined surface behavior - incidents in 2018 briefly closed the Brothers before conduct rules were tightened.
Carry a surface marker, reel, and ideally a personal locator beacon on every dive; follow negative-entry and group protocols exactly. This is no place for rusty skills, and many boats verify logbooks.
最寄りの再圧タンク施設: No chamber offshore; evacuation to mainland facilities takes hours. Availability changes - emergencies route through the boat's protocols, EMS, and DAN.
