A last-minute cancellation has freed up berths on the Belize Aggressor III, and Aggressor Adventures is passing the saving on: $1,000 per person off the October 31 to November 7, 2026 departure. If you can move fast, it's one of the cheaper entry points into liveaboard diving in the Caribbean.
The boat sleeps just 18 guests across nine staterooms, which keeps things personal. On board you get an air-conditioned salon and dining area, a sun deck with a hot tub and loungers, and a shaded cocktail deck for surface intervals. Meals, snacks and drinks are included, and divers get practical touches like individual gear lockers and a camera table.
The itinerary is the reason most people book. It circles Lighthouse Reef and Half Moon Caye, with a chance to descend into the Great Blue Hole — Belize's most famous dive site, a near-perfect circular sinkhole visible from space. Expect walls dropping into deep blue water and the sort of marine life Belize is known for: eagle rays, reef sharks, sea turtles, moray eels, spiny lobsters and dense schools of reef fish. Depending on conditions, you'll log multiple dives a day, with night dives on most evenings.
Aggressor CEO Jay Roberts framed the deal as one for spontaneous divers — the sort who can take a week's holiday at short notice. That's genuinely who this suits: the discount applies only to the October 31–November 7, 2026 sailing, is subject to what's left, and the operator recommends booking quickly through its site or a dive travel specialist.
Can't make that window? Three other Belize Aggressor III charters are currently $700 off per person: November 21–28, December 12–19 and December 19–26, 2026. The December dates overlap Christmas, which could make for a memorable festive week at a knocked-down price.

For divers, this is a low-risk way to try liveaboard life: short itinerary, small boat, world-class reefs, and a price cut that meaningfully changes the maths. For non-divers in the group, Belize's cayes offer plenty above the waterline too — though be aware this is very much a dive-focused charter, so most of the day happens underwater.
