A great hammerhead materialized out of the haze 15 minutes into the first dive, its dorsal fin cutting a clean line through the green water. It circled at the edge of visibility, then a second appeared, then a third — each keeping a constant vigil from a respectful distance. This is the rhythm of a combined shark-diving expedition in Bimini and at Tiger Beach, where encounters with two of the ocean’s most recognizable predators unfold over a week-long liveaboard trip aboard the M/V Dolphin Dream.
Bimini sits about 50 miles east of Miami and Fort Lauderdale, the westernmost island group in the Bahamas, facing the Florida Strait. Its position puts it in the path of migratory great hammerheads from November through mid-April, while Tiger Beach — a shallow sandy expanse on the Little Bahama Bank — hosts resident tiger sharks year-round, with peak safari season running mid-April to mid-July. This article walks through what a combined trip actually looks like, day by day, so you know exactly what you’re signing up for before you book.
During the 2024/2025 season, 11 different great hammerheads visited a single feeding site in one dive — the highest count recorded that season.
A combined hammerhead-and-tiger-shark trip delivers reliably close encounters with both species, but it demands heavy weighting, long bottom times, and a tolerance for repetitive two-hour sits on sand. If you’re a photographer or dedicated shark enthusiast, the payoff is unmatched. If you prefer variety and mobility on every dive, consider a single-species liveaboard instead — the combined itinerary trades some flexibility for density of face time with both animals.

The trip follows a fixed schedule that balances travel, check-in procedures, and maximum time on site. Here’s what each day actually involves.
You board the M/V Dolphin Dream at Blue Heron Bridge Marina in Riviera Beach, Florida, by 6 p.m. After customs paperwork and a boat briefing, dinner is served at 8 p.m., and the vessel departs for the Bahamas after 10 p.m. The overnight crossing puts you at West End, Grand Bahama, by early the next morning. SDM Adventures runs this specific itinerary and caps the group at 12 divers — a deliberate limit that keeps the experience manageable on deck and underwater.
After clearing customs at West End after 7 a.m., you gear up for a check-out dive. No feeding takes place on this first dive — it’s a shake-out to confirm weighting, buoyancy, and comfort. Chumming for tiger and lemon sharks begins on the second dive of the day. The format is a two-tank day with an extensive briefing beforehand. Divers must be heavily overweighted to stay on the sandy bottom at 8–10 m for extended stints; weight belts tend to slip down under the extra lead, so frequent cinching is part of the routine.
Tiger Beach isn’t a beach — it’s a remote area of shallow sand flats and scattered coral patches on the Little Bahama Bank, accessible only in good weather. You’ll do two to four dives per day here, with feeds conducted when visibility allows. On Day 5, all four dives are feeds. The action is relentless while bait is present: expect up to four tiger sharks at once, plus Caribbean reef sharks, lemon sharks, nurse sharks, and often a bull shark cruising the periphery. Named individuals like Emma (roughly 15 feet) and Buttface (smaller, more unpredictable) make regular appearances. DiverNet’s firsthand account of Tiger Beach notes that sustained winds can blow out visibility for days, so the schedule builds in some buffer. After dinner on Day 5, the boat pulls anchor and motors to Bimini for the hammerhead segment. Neal Watson’s Bimini Scuba Center operates the hammerhead season from November to April and coordinates with the liveaboard schedule.
The morning of Day 6 starts with a search for spotted dolphins, followed by two to three dives at the great hammerhead site with chumming. The feed site is a holed metal bait box secured up-current from divers, who form a tight semi-circle on the sand at 8–10 m. Each diver carries a plastic pole — one per person — to prevent hammerheads from swimming between divers and to brace against current. Day 7 repeats the pattern: two morning dives and one after lunch. The 2024/2025 season saw 11 different great hammerheads visit the site in a single dive. Named regulars include Queen, Gaia, Atlas, Aceso, and Enyo. If great hammerheads are already present at Tiger Beach during Days 5–6, the itinerary may shift focus entirely to Tiger Beach and skip the Bimini leg — a rare but possible adjustment. DiverNet’s hammerhead feature covers the full briefing and procedure used by the crew.
The final day brings the trip full circle, with a reef-wall dive that offers a different kind of encounter before heading home.
On Day 8, the boat arrives back in Florida around 6 a.m., with a U.S. customs appointment at 9 a.m. and return to the marina by 9:30 a.m. The final dive of the trip is typically along a reef wall — a sharp contrast to the sand-bottom feeds that defined the previous days. Tiger sharks often come over the top of the wall, down the edge, and straight-on through the sand, creating unpredictable photo opportunities right up to the last minute. If you’ve booked a flight home that same day, plan for an afternoon departure to leave room for customs and gear rinsing.
Booking, Costs & What to Know Before You Go
A trip like this doesn’t come together on a whim. The combined eight-day itinerary runs $5,388 per person (double occupancy on the Dolphin Dream), with an $800 deposit required to reserve a spot. That price includes six days of shark diving, all meals and beverages (domestic beers and some wines), tanks and weights, and photo coaching during the trip. It excludes airfare, airport transfers, crew gratuities, gear rentals, and trip insurance.
Cancellation terms are strict. More than 120 days out, you lose the $800 administrative fee. Between 91 and 120 days, the penalty is 50% of the total trip price. Inside 90 days, the payment is non-refundable. A 4% surcharge applies to credit card payments, 3% for PayPal, and wire transfers carry a $40 bank fee. No refunds are given once the expedition begins — travel insurance is strongly recommended.
Weather is the single biggest variable. Sustained winds and residual swells can blow out visibility at Tiger Beach for days at a time, and the Bimini hammerhead site is also weather-dependent. Book at least six days of hammerhead-specific diving to maximize your odds of sightings regardless of conditions. The trip schedule builds in buffer days, but if you’re on a tight timeline, consider purchasing trip insurance that covers weather-related cancellations.
Seasonality
Great hammerhead season runs November to mid-April, with peak sightings in late January and February. Tiger Beach safaris operate mid-April to mid-July, and Bimini Scuba Center offers summer dive packages from May 23 to September 7. The combined trip described here straddles the shoulder between hammerhead and tiger seasons, so availability is limited — most operators schedule these combos in early February or late March.
Gear & Physical Demands
Diving here is not technically difficult, but it is physically specific. You’ll need heavy weighting — often 20+ pounds more than your usual tropical rig — to stay on the sand at 8–10 m for two-hour stints. Enter the water with a fully inflated BCD and dump air gradually while holding the descent line. Keep your weight belt tight; it will try to slip down under the extra lead. Each diver is issued a plastic pole to maintain spacing and brace against current. Hand signals are essential because sharks often approach from behind, and the divemaster needs to know what you’re seeing.

A reliable dive computer with a clear display is worth the investment for these long, shallow bottom times. The Garmin Descent Mk3i tracks air integration, tissue loading, and multi-gas profiles, which matters when you’re doing multiple two-hour dives per day in the same depth range. For capturing the encounters, a compact action camera like the DJI Osmo Action 6 Bundle handles low-light conditions well at depth and mounts easily on a tray or mask strap.
Before You Go — Bimini & Tiger Beach
When should I book this trip?
Early February is the sweet spot — peak hammerhead season at Bimini and still within the window for reliable tiger shark numbers at Tiger Beach. Book at least six months out; the 12-diver limit means spots fill quickly.
Do I need advanced dive certification?
Advanced Open Water is recommended but not always mandatory. The dives are shallow (8–12 m) but long (two hours), and the conditions demand good buoyancy control and comfort with heavy weighting. If you’re prone to ear-equalization issues on slow descents, you’ll want to sort that before you board.
What’s the biggest downside?
The monotony of the bottom sit. Every dive at both Tiger Beach and the hammerhead site follows the same format: descend, kneel on sand, hold a plastic pole, watch the chum line. If you value swim-throughs, drift dives, or varied terrain, this trip will feel repetitive. The reef-wall dive on the final day offers some relief, but it’s one dive out of roughly 18.
Can non-divers join?
No. This is a dedicated diving liveaboard with no snorkeling program built into the itinerary. The trip targets photographers and shark enthusiasts who want close, consistent encounters — it’s not set up for mixed-ability groups.
What should I pack beyond standard dive gear?
A thick lycra hood or beanie for the two-hour bottom sits — even in the Bahamas, prolonged stillness at depth draws heat. Bring a backup mask and fin straps, a small signalling device (the crew uses them for safety), and a waterproof notebook or phone case for logging IDs of named sharks you encounter.
Why This Trip Stays With You
The thing that lingers isn’t the size of the tiger sharks or the dorsal profile of a hammerhead against the surface — it’s the repetition. After six days of watching the same individuals return to the same bait box, you start recognizing Emma by the notch in her dorsal fin and Queen by the width of her cephalofoil. That familiarity, built through patient hours on a square of sand, is what separates a shark dive from a shark encounter. If that kind of slow-built recognition appeals to you, the Exumas Cays Land and Sea Park offers a different kind of Bahamian marine experience worth tacking onto the same trip — one built on protected reefs and nurse sharks in gin-clear shallows, no bait box required.

If this kind of focused wildlife encounter appeals to you, the Bahamas has plenty more to offer beyond the shark sites. The Devil’s Backbone reef system near Bimini is worth a surface interval, and Harbour Island’s pink-sand beaches make for a calm post-dive recovery stop. For a completely different pace, stand-up paddleboarding at French Leave Beach trades adrenaline for quiet mangrove edges — a solid option if you’re extending your Bahamas trip beyond the liveaboard.
