Shark & Yolanda Reefs

Two coral towers rise from a shared plateau off the very tip of Sinai, separated by a saddle and swept by the currents that make Ras Mohammed famous. Divers drop at Anemone City, cross to Shark Reef's vertical wall - a drift over deep blue with snapper, batfish, and barracuda massing in summer - then finish over Yolanda Reef among scattered toilets, bathtubs, and pipe fittings: cargo spilled by the freighter Jolanda, which ran onto the reef in 1980 before her hull slid down the drop-off; technical divers relocated it below 145 meters in 2005. A resident Napoleon wrasse usually inspects the traffic. In July and August the fish aggregations here rank with anything in the Red Sea.

您此行的高光时刻: Summer snapper and batfish walls; Shark Reef's sheer drop; Yolanda's porcelain cargo field; resident Napoleon wrasse.

地形地貌: Two coral towers on a shared plateau over a wall that drops several hundred meters

水流: Flow at the point can strengthen mid-dive and split around both towers; guides read it on descent.

入水方式: Dived as a drift inside Ras Mohammed National Park; groups usually drop at Anemone City and finish over Yolanda Reef.

危险因素: Current shear at the point, boat traffic at the surface, and the temptation to overstay depth on the wall.

许可证与规定: National park fee, normally collected by the operator.

保育: Ras Mohammed National Park rules apply: no touching, no gloves, no collection of the Jolanda cargo.

高氧（Nitrox）: 在此值得使用——各潜点深度落在富氧空气（nitrox）能有效延长免减压时间的区间（前提是持有相应认证）。
