Shear Water — a compact liveaboard for shark diving

Shear Water is chosen for the animals, not for resort-style living. The programme centres on Tiger Beach and Bimini, with shark diving at its core and opportunities to dive with Jim Abernethy, whose work combines marine conservation, documenting and photography. The boat suits divers who want a small group, repeated time in the water and a working dive platform rather than a floating hotel. Its capacity is limited, and the route is built around encounters that depend on being in the right place, properly briefed and ready to enter the water. Nitrox is available for those looking to extend bottom times, at an additional cost.

Shear Water has the practical feel of a compact working dive boat. Its glass-reinforced-plastic hull and twin engines support a vessel built around getting divers to the water and back efficiently, rather than spreading space across grand public areas. On board, the arrangement is simple: an indoor, air-conditioned saloon, an open-air saloon and a dedicated dive deck. Ten guests is enough for a sociable boat without turning every movement into a queue. The layout matters most between dives, when the group can remain close to the action instead of disappearing into separate hotel-style spaces.

With space for 10 guests, Shear Water creates a small working group quickly: the same people share the saloon, the dive deck and the briefings throughout the trip. The crew speaks English, and the boat’s role is clear from the start—feed the divers, turn the boat around for the next dive and keep the shark programme moving safely. The strongest reason to choose it is the chance to dive with Jim Abernethy, a marine conservationist, documentarian and photographer. Groups and private charters are also possible.

The recorded routes run from Florida to Florida and focus on Tiger Beach and Bimini. Tiger Beach Weekend lasts 7 days and 6 nights. The Tiger & Great Hammerhead Expedition is offered mainly as a 7-day, 6-night trip, with one recorded 8-day, 7-night departure. Tiger Beach is the name that defines the programme; Bimini appears on the routes and carries a fuel surcharge when included. No verified site descriptions or depths are available for these itineraries, so the page does not invent a wall, pinnacle, wreck or cleaning station where none has been documented.

Shear Water requires at least 75 logged dives, with OWD or an equivalent certification as the minimum level. A dive guide is included, and the crew operates in English. The trip is therefore aimed at divers who can manage themselves in the water and follow a briefing in a shark-diving environment, rather than at first-time divers. The boat lists full safety equipment, but details such as guide-to-diver ratios, group sizes, oxygen, defibrillator and recall procedures are not given.

The dive deck provides personal storage, a camera table and separate rinse tanks for underwater cameras. Two 11 CFM compressors fill the boat’s included 12-litre tanks; 15-litre tanks are available at extra cost. Nitrox is available for an additional charge, but the blending system and tank valve type are not given. Weights are included, while equipment rental is not part of the standard arrangement. No tender operation, entry system or brand list is specified, so divers should expect the boat’s own briefing to cover how each site is entered and exited. The boat is not set up for technical diving.

Between dives, guests can choose the air-conditioned indoor saloon or the open-air saloon. The spaces are close enough to the dive operation that the next entry never feels far away, but they give the group a choice between shade and fresh air. There is no Wi-Fi, which suits a trip organised around the sea rather than constant connection. The camera table and separate camera rinse tanks also give photographers somewhere purposeful to work between dives.

The day is organised around diving, meals and the short pauses between them rather than a sightseeing schedule. Full board and snacks keep food available around the dive programme, while the indoor and open-air saloons provide places to sit before the next briefing. The boat’s shark focus means the important transitions are practical ones: prepare gear, listen to the guide, enter the water, return to the deck and reset for the next encounter. Exact wake-up times, dive counts and night-diving arrangements are not specified.

Meals combine Western and local food, served either buffet-style or as plated meals. Snacks are available throughout the day, alongside full board and non-alcoholic drinks. That matters on a shark-diving trip: the table is where divers refuel between entries, compare what came past the bait, and get ready for the next briefing. The food is practical and varied rather than presented as a separate culinary programme.

The cabins are on the lower deck. The Guest Cabin has four twin berths with privacy curtains, while the Standard Cabins use upper and lower bunks, storage beneath the lower berth, air conditioning and natural light. The Guest Cabin has access to two bathrooms with hot-water showers, soap, shampoo and conditioner; the Standard Cabins use a shared bathroom. These are compact sleeping quarters made for a week centred on diving, not for spending the afternoon indoors. Privacy curtains make the four-berth cabin easier to settle into, while the smaller bunk cabins suit two guests who prefer a simpler arrangement.

The recorded departures and returns are in Florida. Transfers are not included and are arranged separately. Arriving in Florida the night before is sensible, particularly when the itinerary depends on making the boat’s departure without a connection delay.
