Seadoors is a 27-metre steel liveaboard purpose-built for diving in the Philippines. She carries her guests in 8 air-conditioned cabins on two decks - standard and deluxe sea-view options, each with a queen and a single bed, en-suite hot-water bathroom and private toilet - plus a central air-conditioned lounge and a shaded open-air dining area. A spacious dive platform, individual gear drawers, two compressors with nitrox blenders and rebreather support equip her for serious diving, served by 16 crew including dive guides and a cruise director. From March to July she runs trips to the remote UNESCO-listed Tubbataha Reefs in the Sulu Sea; from July to March she explores the Visayas and Malapascua, home of the thresher sharks.
