Doña Marilyn

The Doña Marilyn was an inter-island passenger ferry lost in Typhoon Unsang in October 1988, a disaster that killed a large number of the people aboard; accounts of the toll vary into the hundreds. The roughly 90 m hull now lies on its starboard side on sand at about 33 m, thickly furred in black coral and soft growth, sheltering scorpionfish, sweetlips, and clouds of baitfish, with rays sometimes resting in its lee. Dive it as what it is, a grave as well as a reef: no souvenirs, restrained penetration for the trained only, and quiet respect for the door frames people once walked through.

您此行的高光时刻: A large, coral-carpeted ferry hull, rich fish life, sobering history handled respectfully

地形地貌: Hull lying on its starboard side on sand at about 33 m

水流: Exposed position; current across the hull is common and dives are planned around it.

入水方式: Roughly an hour's boat ride from Malapascua in open water; dived when seas allow.

危险因素: Depth, nets and snagged lines in places, silt inside, and open-sea current; penetration only with wreck training.

保育: Treat as a maritime grave: take nothing, disturb nothing, and keep contact off the hull's growth.
