Your Host

bill-at-seaBill Acker, founder of the Manta Ray Bay Hotel and Yap Divers is proud to share his love of Yap and diving with quests from all over the world. A resident of Yap for almost 30 years, Bill is eminently qualified to make your Micronesian dive experience one that you’ll never forget.

Bill first came to Yap as a Peace Corps Volunteer in 1976. Bill originally hails from Austin, Texas and after graduating from High School in Garland, he attended the University of Texas where he graduated with a degree in marketing.

Bill is constantly asked “What brought you to Yap?” and invariably answers with tales of reading Mitchner, Conrad and Kipling plus watching anything produced about the South Pacific. The lure of the tropics has been in Bill’s blood since his early childhood days.

After two years in the Peace Corps, Bill attended the University of Hawaii Graduate School of Business and was there two years when a call for assistance came from old friends and “family” in Yap. Bill left Honolulu and became the manager of the WAAB Transportation Company where he stayed for the next 13 years. As part of his accomplishments while directing WAAB Transportation, Bill took up the sport of scuba diving.

One thing led to another and one of the results of this new hobby became known as Yap Divers. Bill conceived the idea of opening Yap’s first dive shop in the fall of 1985 and by the Summer of 1986, Yap Diver’s was affiliated with both NAUI and PADI and opened for business. As they say, “The rest is history”.

With guidance from the late Paul Tzimoulis, Hall of Fame dive pioneer and publisher of SKIN DIVER MAGAZINE, Bill developed the manta dives and the publicity that has culminated in Yap being one of the top international dive destinations in the world. With very few exceptions, all of the dive sites in Yap were found, explored and named by Bill.

With over 9,000 dives in the waters of Yap, Bill is a member of the original class of SSI Platinum Pro Divers. As a PADI instructor, Bill remains active in exploring new dive sites and teaching the sport to people interested in sharing his love for the ocean environment.

Along the way, Bill met and married Patricia Mangthin of Yap and they have 4 wonderful children (Numie, Nathan, Valerie and Opie). All of the family are active in the sport of diving and share in their father’s commitment to safety and preservation of this natural resource.

Bill and his family own and operate the Manta Ray Bay Hotel & Yap Divers. He can be found at the hotel 7 days a week, ready to help with suggestions on diving, photography, fishing or just relaxing on the back deck. As a family owned and operated dive resort, you can be sure that your satisfaction is taken very seriously and that the “boss” is around to help you in the event assistance is required.

We stayed at the hotel and dove with Manta Ray divers in early December 2017. The hotel is very comfortable, well run and staffed with wonderful employees. During our visit my wife came down with an illness and the consideration and support from the hotel and dive staff could not have been more

The staff couldn't be more friendly and accommodating. Food is good, (worth upgrading to include all meals). Diving is good more

The best place to stay in Yap. The resort is really nice and clean, the scuba diving is great, and the docked ship that houses the bar, restaurant, and movie screen is very cool. I really enjoyed my stay more

The whole place centers around the scuba diving operation. Probably better to find somewhere else if you're not a diver. The dive operation was generally good, but a little too laid back - schedules weren't always clear, and sometimes would change without any notice. Sometimes it was hard to tell if this was really because of changing tides/weather or because of the island pace of life. Pizza is a surprisingly good option at the more
