Best Liveaboards in the Caribbean: Complete Guide to the Top Boats
A liveaboard is the easiest way to dive the Caribbean's best sites without wasting time on long boat commutes. You sleep on the water, wake up on the reef, and dive three or four times a day for a full week. The region is comfortable and forgiving year-round, with warm water, mild currents, and dramatic walls that drop into deep blue — a gentler introduction to liveaboard diving than long-range Pacific trips.
This guide covers the best liveaboards in the Caribbean — where each one sails, what you will see, how much a week costs, and how to book. Every boat below is part of the Aggressor Adventures fleet, all running Saturday-to-Saturday weekly charters, and all bookable directly through Be Underwater.
What Are the Best Caribbean Liveaboards?
The top Caribbean liveaboards are the Bahamas Aggressor II for tiger and Caribbean reef sharks around Nassau and the Exumas; the Belize Aggressor III, IV and V for the Great Blue Hole, Turneffe Atoll and Lighthouse Reef; the Cayman Aggressor IV for the famous walls of Little Cayman's Bloody Bay Wall; the Roatan Aggressor for affordable, uncrowded reef diving in Honduras's Bay Islands; and the Turks & Caicos Aggressor II for dramatic wall diving out of Providenciales.
Caribbean liveaboards run year-round, with rates starting around $3,395 per person for a week in a shared cabin. The main thing to plan around is the Atlantic hurricane season, roughly June through November — most boats keep sailing, but build some flexibility into your dates during peak season.
Why Dive the Caribbean by Liveaboard
Most Caribbean dive destinations are easy to reach from shore, so a liveaboard here is less about covering huge distances and more about comfort and access. You get boat-based diving on sites that day boats cannot reach efficiently — outer atolls, offshore walls, remote shark aggregations — while unpacking only once for the whole week. Conditions are generally easy: warm water, good visibility, and currents that are usually mild to moderate, which makes the Caribbean a good region for divers moving up from day-boat trips into their first liveaboard.
- Season: Year-round diving. Water stays warm (around 78–84°F / 26–29°C) throughout the year, so there is no true off-season for temperature.
- Hurricane season: June through November across the wider Caribbean and Bahamas. Charters keep running, but weather can affect itineraries — Aggressor's cancellation and rebooking policies apply, and it is worth staying flexible with travel dates in late summer and fall.
- Cabin pricing: Rates listed as "from" are per person, per week, based on double occupancy in a shared cabin. Solo travelers can share a cabin or pay a single supplement.
7 Best Caribbean Liveaboards (Detailed)
1. Bahamas Aggressor II
Sailing weekly out of Nassau, the Bahamas Aggressor II is the Caribbean's go-to boat for shark diving. Itineraries cover the Exuma chain and nearby shark sites, with regular encounters with Caribbean reef sharks and, seasonally, tiger sharks. Expect drift-friendly reef dives, swim-throughs, and walls in clear Bahamian water.
20 guest berths · 58 weekly departures · from $3,695 per person.
Best for: Divers who want shark encounters without a long-range expedition — the Bahamas Aggressor II is the most direct route to reliable shark diving in the Caribbean basin.
2. Belize Aggressor III
Departing from Belize City, the Belize Aggressor III is the classic way to dive the Great Blue Hole, a UNESCO World Heritage site, alongside the reefs of Turneffe Atoll and Lighthouse Reef. Expect swim-throughs, spur-and-groove reef formations, and regular encounters with nurse sharks, eagle rays and turtles.
18 guest berths · 56 weekly departures · from $3,695 per person.

3. Belize Aggressor IV
A sister ship on the same Belize route, the Belize Aggressor IV covers the Blue Hole, Turneffe and Lighthouse Reef with a larger group size — useful if you are traveling with a dive club or a larger group of friends and want everyone on one boat.
20 guest berths · 64 weekly departures · from $3,695 per person.
4. Belize Aggressor V
The smallest and most intimate of the three Belize boats, the Belize Aggressor V carries fewer guests on the same Blue Hole–Turneffe–Lighthouse Reef route, with more space per diver and a lower price point.
14 guest berths · 65 weekly departures · from $3,595 per person.
Tip: If "belize aggressor iv" or a Blue Hole trip is on your list, all three Belize boats run nearly identical itineraries — pick by group size and budget.
5. Cayman Aggressor IV
Sailing from George Town, the Cayman Aggressor IV reaches Little Cayman's Bloody Bay Wall — widely considered one of the best wall dives in the Caribbean, dropping from around 6 meters to well over 1,000 meters in open ocean. Expect pristine visibility, dense sponge and coral growth, and the occasional reef shark cruising the drop-off.
18 guest berths · 64 weekly departures · from $3,695 per person.
6. Roatan Aggressor
Based in Honduras's Bay Islands, the Roatan Aggressor is the best-value boat on this list and a strong answer to anyone searching for a Honduras liveaboard. Reefs around Roatán, Utila and the surrounding banks are healthy and uncrowded compared to more famous Caribbean destinations, with abundant macro life, seahorses, and easy-to-moderate wall dives.
18 guest berths · 67 weekly departures · from $3,395 per person.
Best for: Divers who want Caribbean liveaboard diving at the lowest entry price, without giving up reef quality.
7. Turks & Caicos Aggressor II
Sailing out of Providenciales, the Turks & Caicos Aggressor II covers steep coral walls dropping from shallow reef flats into deep water, with strong visibility and healthy coral cover. Trips run close to spots where humpback whales migrate in winter, adding a chance of surface sightings on top of the diving. Searches for "turks and caicos aggressor ii" specifically point to this boat.
18 guest berths · 58 weekly departures · from $3,695 per person.
Beyond the Caribbean: Pacific Aggressor Liveaboards
If you are comparing Caribbean options against Pacific bucket-list trips, Aggressor also runs three longer-range liveaboards out of Costa Rica and Ecuador. These are a step up in cost, travel time and typically required experience level compared to the Caribbean boats above.
- Cocos Island Aggressor — Isla del Coco, Costa Rica. Famous for schooling hammerhead sharks. From $6,849 per person.
- Okeanos Aggressor II — the answer for anyone searching best liveaboard Costa Rica, also sailing to Isla del Coco for hammerhead and big pelagic encounters. From $6,399 per person.
- Galapagos Aggressor III — the top pick for a Galapagos Aggressor search, sailing Ecuador's Galápagos Islands for whale sharks, hammerheads and marine iguanas. From $7,300 per person.
These three are Pacific expeditions, not Caribbean trips — mentioned here for comparison since they share the same operator and booking process.

Diving is good year-round thanks to consistently warm water. The main consideration is Atlantic hurricane season, roughly June through November — trips still run, but it is worth building flexibility into your travel dates during those months.
Are Caribbean liveaboards suitable for beginners?
Yes. Conditions across the Caribbean are generally easier than long-range Pacific destinations — warm water, good visibility, and mild to moderate currents. Most boats require at least Open Water certification, but you do not need advanced experience the way you would for a Galápagos or Cocos Island trip.
