C-53 Felipe Xicotencatl

The Felipe Xicotencatl is Cozumel's set-piece wreck dive: a mid-century minesweeper that served in the Mexican navy and was sunk deliberately in 2000 as an artificial reef near Chankanaab. She sits upright and whole at recreational depth, which makes her a teaching wreck in the best sense — guides lead simple line-of-sight passes through opened corridors and the engine room while glassy sweepers swirl in the dark spaces. Outside, the hull carries a growing fur of sponge and hydroid, patrolled by barracuda and the occasional resting stingray on the surrounding sand.

您此行的高光时刻: Upright intact hull, guided interior corridors, glassy sweepers, easy depth for a wreck.

地形地貌: Intact steel minesweeper resting upright on flat sand near the reef line.

水流: Gentler than the southern drift sites; occasional along-hull flow.

入水方式: Moored descents near Chankanaab; mild conditions on most days.

危险因素: Overhead sections require training and a guide; sharp steel edges; silt inside if finned carelessly.

保育: Artificial reef inside the marine park; take nothing and touch nothing.

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）。
