globe th CopyOman, a nation encompassing vast deserts, sparkling riverbed oases and miles-long coastlines  is located on the Arabian Peninsula, bordered by the United Arab Emirates, Saudi Arabia and Yemen.  Its coastal waters include the Arabian Sea and the Gulf of Oman. Two of its territorial regions, Madha and Musandam, are completely surrounded by the UAE on their land borders, while the Strait of Hormuz and Gulf of Oman form Musandam's coastal boundaries.  From the late 17th century, the Omani Sultanate was a powerful empire, vying with Portugal and Britain for influence in the Persian Gulf and Indian Ocean.  Today, Oman ranks as one of the most improved nations in the world in terms of development. A significant portion of its economy is tourism and trade of fish, dates and other agricultural produce, setting it apart from the oil-dependent economies of its neighbors.

Aggressor Fleet comes to Oman

The Aggressor fleet is set to launch a new liveaboard in Oman in July 2017.  

While there are, indeed, other liveaboard choices here, they are simple, traditional dhow-style boats.  Aggressor offers the high standards & excellent amenities most of you are searching for in a diving holiday and we feel entirely confident in recommending the new Oman Aggressor for your Oman liveaboard experience.

Four itineraries to choose from

Four distinct itineraries are being offered by Aggressor:

From November to May the diving is concentrated in the Hallaniyat Islands which offer a plethora of the "big stuff" including a resident population of humpback whales.

In July and August the boat will move to the Daymaniyat Islands which are best known for fantastic corals and an abundance of turtles.

In September and October the Musandam Peninsula with it's limestone caves and huge numbers of pelagics is the best place to be.

And, early in November each year you can choose the 10-night transit trip which runs from the Daymaniyat Islands to the Hallaniyat Islands and takes in the best of all worlds.

These 7-night diving cruises through the group of 9 rocky Daymaniyat Islands will take you into Oman’s first Marine Reserve. Amongst other things, these islands are well-known for their populations of nesting hawksbill and green turtles, healthy corals & immense schools of fish ... read more ...

You’ll find sandy, relatively shallow sea beds facing Oman while you get some nice walls & drop-offs on the opposite side.

The corals are very rich and healthy and are one of the premier features of diving here. There are areas where the soft coral colors are just ethereal .... soft orange, yellow and purple. You’ll find some critter life, but far less than in the neighboring Red Sea. The most common finds are crabs, crayfish, scorpionfish, stonefish, sea horses and reputedly some really large, colorful nudibranchs.

Turtles are ubiquitous ... as are the morays.

The staggeringly immense schools of fish are perhaps the biggest draw for divers: swirling masses of jacks, snappers, batfish, barracuda, red-toothed triggerfish, damsel fish and goat fish.

And don’t despair. You’ll have plenty of the big guys, too ... huge stingrays & eagle rays, leopard sharks, bottlenose dolphins, spinner dolphins ... with the occasional passing humpback whale or mola mola appearing out of the blue. July to September tends to be the time for whale sharks, based on the plankton bloom at that time.

Do note that water temps can be cool as you go below 10 meters, due to thermoclines – so make your wetsuit choices carefully. Also, currents can be strong in places.

At the northern tip of Oman, the Musandam peninsula offers a fjord-like geography on the Straits of Hormuz. The water is warm year-round and, as with Oman’s other regions, is chock full of life-sustaining nutrients which make the marine life sublimely happy and incredibly prolific ... and divers a tiny bit frustrated due to the viz. But don't despair! ... read more ...

That being said, the visibility can change from hour to hour depending on the currents, so you just have to keep in mind that the abundance of marine life you encounter is due to the plankton and other nutrients in this environment. Do note that the currents at Musandam can be challenging and may be best suited to experienced divers.

You’ll love the striking coral-covered drop-offs here as well as the amazing number of species represented at the dive sites. Thanks to the plankton and currents, you’ll be treated to great swells of pelagic fish (jacks, barracuda & king fish) and pelagic animals (manta rays, sting rays, marbled eagle rays, dolphins, mola mola & leopard sharks) ... as well as whale sharks in season (May to October).

And, as everywhere in Oman, the ever-present turtles ...

Limestone caves have alluring chambers & tunnels where you’ll find loads of lobsters, shrimp and other critters .... along with sharks & rays which like napping on the sandy bottom.

A small archipelago of 5 islands located off the south eastern coast of Oman, offer divers an environment generally unaffected by the scourges which have damaged corals & marine life in other parts of the world. This is the area where the new Oman Aggressor will concentrate her diving for much of the year ... read more ...

The diving is also somewhat exploratory, as many sites remain undiscovered due to the lack of diving tourism that exists here. New sites are being discovered all the time.

Perhaps the greatest excitement revolves around a resident population of humpback whales but also there’s the added attraction of possible encounters with sperm whales. Manta rays and huge schools of dolphins are almost certain sightings ... along with oceanic manta rays, giant groupers, giant catfish and mobulas ... plus huge schools of pelagic fish.

With plentiful, healthy corals come plentiful, healthy reef fish ... multiple species and colors in every hue.

Depending on conditions, you’ll enjoy some good wreck diving, too. The first ship sunk in WWI, the British cargo ship “City of Winchester”, sits in 28 - 30 metres of water in the Hallaniyat Islands. Interestingly, the hull has now collapsed, exposing the engine & boiler and divers will find all the ship’s remains graced with soft corals, anemones & fans ... and populated by scorpion fish, lion fish & honeycomb morays.

Take a look at what you can expect during the different seasona at Hallaniyat : November & December bring rays, giant catfish, mobulas, leopard sharks, schools of jacks, barracudas, morays eels, honeycomb morays, nudibranchs and fish in the thousands. Giant oceanic manta rays can be encountered. Close to shore there is plenty of kelp with fascinating animal life.

From January to March you can be almost guaranteed humpback whale encounters with their songs in the background while diving with giant groupers and the usual cast of characters.

In April, divers normally meet yellowfin, barracudas, schools of jacks, big rays, octopus, giant groupers, leopard sharks, milk fish, schools of dolphins and beautiful reef fish in the thousands ... as well as humpback whales. April can have strong currents.
