Located near the southwest end of Willoughby Bay, Mamora Bay is an extremely well protected bay with quiet and protected anchorage, an exclusive marian and club, but little in the way of shops or markets for provisions.
The biggest draw in Mamora Bay (aside from the well-protected anchorage) is the St, James Club (visible in the image above - green roofs), an exclusive and expensive club that is popular with large yachts and their crew. There are 15 slips at the club, and there is cable TV, phone, water and ice available here. The club is located on the east side of the bay. There are no customs facilities in Mamora Bay, so you must be cleared through before arriving here.
Mamora Reef is clearly visible in the image above on the right side of the entrance channel to Mamora Bay. The ledge of coral extends from small Sober Island about seven-tenths of a mile to the northeast at the opening to Willoughby Bay. Cruising boaters arriving from the Willoughby Bay area or points east must mind this reef when approaching Mamora Bay. If you are approaching from the west, mind Standfast Point, which is about a half-mile southwest of the initial approach to Mamora Bay.
The entrance channel into Mamora Bay carries at least 11-foot depths, but the outer channel is not marked. Waypoint N17 00.416 W 61 43.589 will put you about a half-mile outside of the bay itself. From this point, set a course of 320 degrees true. This will take you into the bay to intercept the harbor buoy shown in the image above northwest of Sober Island.
