Those in search of Andros bonefish can stay in places that range from upscale resorts, likeKamalame Cayand Tiamo, to simpler fishing lodges such as the famous Mangrove Cay Club. The ultimate way to fly-fish for Bahamian saltwater species, however, is aboard theEleven Mothership, a 74-foot Hatteras yacht, part of the Colorado-based Eleven Experience group, which ownsBahama Houseon Harbour Island. From mid-October to May, the vessel is anchored off the uninhabited southwestern coast of Andros, a wilderness of tidal creeks, deserted cays, tangled mangroves and mile-upon-mile of white-sand flats. (The Water Cays are generally reckoned to be some of the best wading flats in the world.) This is a place of vast skies and eerie silences. Unexploited and unpolluted, the waters are teeming with marine life.
