But bad weather, particularly during the typhoon season, as well as poor maintenance, overloading of vessels and lax enforcement of regulations, has often brought disaster to sea travellers.
Here is a list of major ferry disasters in the Philippines over the past two decades:
September 6, 2009: Five people are confirmed killed and more than 60 are left missing after the Superferry 9 tilts sharply and then sinks near Zamboanga.
May, 2009: Wooden-hulled MV Commander 6 cracks open and sinks just south of Manila, leaving 12 dead.
December, 2008: Ferry Maejan capsizes off the northern Philippines, leaving 30 dead.

June, 2008: The Princess of the Stars ferry, owned by Sulpicio Lines, capsizes at the height of a typhoon. Of the 850 on board, only 57 survive.
February, 2004: A fire breaks out on Superferry 14 near Manila Bay, leaving 116 dead. Islamist groups later claim they planted a bomb aboard the vessel.
April, 2000: The overloaded ML Anahanda, which was supposed to be operating only as a cargo vessel, sinks off the island of Jolo. About 100 of the estimated 150 people on board die.
