Cabins and Boat Layout


A luxury liveaboard in the truest sense of the word, the MV Cayman Aggressor IV is capable of providing berths for up to 18 guests. Each cabin has some common facilities such as air-conditioning, TV/DVD/Media facilties and head plus shower bathroom amenities. However, the key differences are:

  • Cabin No.1 – Master Stateroom No.1 is the largest cabin on the vessel. It features one queen-sized double bed and is more spacious than the other cabins at 8 x 12 feet in size.
  • Cabin No’s 2-7 – Deluxe Staterooms that are marginally smaller than Cabin No.1 at approximately 7½ x 7 feet but feature the same amenities and features. In addition, they feature a porthole style window and double bed (lower) with a single bunk above.
  • Cabin No’s 8-9 – Twin Share Staterooms. These are marginally smaller at 6½ x 6ft in size and feature twin bunk beds. The two adjoining cabins have shared bathroom facilities. However, the other conveniences, such as air-conditioning, remain.

The layout of MV Cayman Aggressor IV is very similar to the winning formula of the other Aggressor fleet vessel. Cabins are on the lower deck. Moving upstairs to the main deck there’s a salon area where you can relax with other guests, read a book from the library and study your fish! Or watch a movie on the TV. For photographers, there’s a special camera room with a table and charge point to mirror the camera table for divers on the dive deck – allowing you ample opportunity to tweak your underwater shots and prepare for the next dive.

Master Stateroom


A selection of beers and wines are available from bar when the diving is done – or when you’re enjoying food in the spacious dining and buffet area next to the galley. Here, 3 times a day, the chef prepares a combination of delicious local foods made with fresh ingredients combined with more traditional western meals. Still hungry? There are snacks available throughout the day to nibble on before and after each dive. Soft drinks, tea and coffee and always available too.

Relaxing in the hot tub.


There’s a hot tub and sun deck up on the top deck, together with sun loungers for those relaxing surface intervals as you off-gas and reflect on what you’ve seen. Or simply chill, relax, slow down and gaze into the blue skies and equally blue waters. The sun deck is also partially covered and you have the option to doze in the shaded areas before the next dive briefing.


Diving onboard Cayman Aggressor IV


There’s a roomy dive deck with ample space to store equipment and change pre/post-dive.
