West Bay Offshore Bite Delivers Tuna, Wahoo and Mahi Mix

Yellowfin and blackfin showing up alongside wahoo, mahi, grouper and trigger fish off West Bay is the kind of mixed bag that tells tuna anglers the water is doing more than one thing at once. It points to bait in the system, enough current or structure to hold different predators, and a bluewater window that can pay off fast if you choose the right spread and the right stop.

That picture came into focus in FishingBooker’s May 9, 2026 West Bay report, where Big Reef Charters said the trip produced “a nice mixed bag of wahoo, tuna, mahi, grouper and trigger fish.” The report did not hinge on one giant fish. That is exactly why it matters. A day that delivers tuna plus speed fish and surface bait hunters usually says more about the fishery than a lone trophy does. It says the offshore zone off West Bay, Cayman Islands, was holding enough life to keep multiple species active in the same run.

Big Reef Charters’ listing backs that up with a roster that reads like a proper Grand Cayman offshore menu: yellowfin tuna, blackfin tuna, blue marlin, white marlin, mahi mahi and mutton snapper. FishingBooker lists Captain Wayne at the helm on a 34-foot pilothouse that carries up to 8 passengers. A separate Fish Cayman Islands listing puts Captain Nigel Ebanks on the 34-foot Crusader “2 Rude” for an 8-hour full-day deep-sea trip, trolling the wall or running to the 12-mile bank for wahoo, yellow or blackfin tuna, mahi-mahi or marlin.

For tuna anglers, the detail worth filing away is the yellowfin playbook. That listing says the most productive technique is drifting and chunking, which fits the kind of mixed offshore pattern seen here. When mahi are in the spread, surface life is usually part of the equation. When wahoo are mixed in, there is enough speed and bait movement to make trolling relevant. When tuna are on the list too, the offshore edge is not just pretty water, it is fishable water.

West Bay also sits inside a fishery with serious conservation structure. Visit Cayman Islands calls fishing the unofficial national sport and says blue marlin, tuna, wahoo, mahi-mahi and barracuda are caught year-round. The Cayman Islands Department of Environment says marine parks were first established in 1986, expanded in 2021 to cover around 50% of coastal waters, and that there are no fishing license requirements for residents or visitors. Around half of the near-shore waters are also designated Marine Protected Areas under Marine Park Regulations and the National Conservation Act, which helps explain why offshore opportunity and coastal protection now coexist in the same island fishery.
