SS Nebo

The Nebo never finished her first job. The new British steamer left England in 1884 loaded with sections of railway bridge for the expanding Natal colony, and on 20 May, on her maiden voyage's final approach along the coast, she went down over Aliwal Shoal in heavy weather. The court of inquiry blamed the shoal; local legend has long argued about whether she struck it at all or was simply overwhelmed, capsized by her towering deck cargo — either way, her crew got away in the boats, and the brand-new ship settled upside down on the sand. That inverted attitude still defines the dive. She lies hull-up in about 27 meters, her plates now a reef roof: divers cruise the intact turn of the bilge, peer beneath the edges where the hull stands off the sand, and circle the prop and rudder area at the stern. Brindle bass and shoals of goldies have colonized her as thoroughly as the neighboring Produce, ragged-tooth sharks appear in the cooler months, and after 140 years she ranks among the oldest routinely dived wrecks on the African coast.

沈没の経緯: Lost in heavy seas over Aliwal Shoal on her maiden voyage, 20 May 1884.

コンディション: Inverted hull substantially intact after 140 years, with openings spreading along the seams

洞窟貫通（ペネトレーション）: Limited. Gaps under the inverted hull tempt divers in; treat them as true overhead spaces — dark, silty and for trained teams only. オーバーヘッド環境への進入には専門的なトレーニングが必要です——最低限、レック・ダイビング認定資格が必要で、完全貫通には技術的なレック・トレーニングが求められます。

推奨ライセンス: Advanced Open Water

流れ（カレント）: Moderate · 透明度: 8–25 m

海洋生物: Brindle bass under the hull, harlequin goldies over the plates, seasonal ragged-tooth sharks, moray eels, and rays on the surrounding sand.

危険生物・リスク: Surge, current, and overhead spaces beneath the hull
