Belize Aggressor IV

BAIV Yacht0 XL Ext opt 1

The 138-foot Belize Aggressor IV is a luxurious liveaboard with 10 spacious cabins for 20 guests. Her Belize scuba diving includes colorful walls & exploration of the popular Blue Hole.


A word from Dom  "The sleek Belize Aggressor IV is one of my personal favorite Caribbean liveaboards.  She carries divers to explore the beautiful barrier reef of Belize & the magical Blue Hole. There's more to this area than many divers may think. The wall dives are exquisite & they hide diverse species of weird & wonderful critters. The vessel itself is spacious & inviting."  ...  Dominick Macan

    Every Saturday, the Belize Aggressor IV departs from the heart of downtown Belize City to visit Lighthouse Reef, Half Moon Cay and the famous Blue Hole. 

     Itinerary information and map ... open
      The Blue Hole, a collapsed freshwater cave system, is approximately 1000 feet across and over 400 feet deep and was made famous by Jacques Cousteau. Once descended into the Blue Hole you will see beautiful vertical stalactite formations. 

    Beyond that, Belize is a wall diver's paradise. Sheer walls like Painted Wall, Half Moon Caye Wall and Quebrada are adorned with huge crimson gorgonians and giant orange elephant ear sponges. Moray eels, spiny lobsters and tiny arrow crabs hide in every crack, crevice, cave and tunnels of these beautiful coral formations. 

    These are just a few things you will see at Lighthouse Reef, Half Moon Cay and Turneffe Reef.

    Guests are met at the airport on Saturday and transferred to the yacht.  Or you may arrive on your own between 3 pm & 6 pm.  At 6 pm the yacht departs for its night anchorage.  Sunday through Thursday there is unlimited diving throughout the day and a night dive each evening.  Diving ends Friday before lunch and you'll return to port.  As a land-tour of Belize is highly recommended (Mayan ruins, a cave tubing ride through the jungle, or a canopy tour through the tree tops) the Aggressor offers a Friday afternoon tour to give you a taste. After a final night on board, check-out is Saturday morning at 8 am.  Transportation is provided back to the Belize City International Airport Saturday morning.
