Corveta Ipiranga (V17)

The Brazilian Navy corvette Ipiranga (V17) struck rocks and sank off Noronha in 1983, settling upright and startlingly intact on a sand plain around 60 m down. In the archipelago's clear water she appears whole from far above: guns trained, masts standing, companionways open, a warship paused rather than lost. The crew abandoned ship successfully, so she is dived without the weight of a grave, but with every demand of depth - this is a staged-decompression dive for trained technical divers with proper gas, run by operators equipped for it. Reef sharks and barracuda patrol the superstructure, and the light at 60 m in 30 m visibility is something recreational profiles simply never show.

您此行的高光时刻: An intact upright warship in exceptional visibility, one of South America's benchmark technical dives

地形地貌: Sand and rock plain around an upright warship

危险因素: Depth beyond recreational limits, mandatory decompression, current on the ascent line.

保育: Within the marine national park; nothing may be removed from the wreck.

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）。
