The world‘s finest diving

RIA Yacht14 XL Ext opt

The Rock Islands Aggressor, a spacious catamaran specifically built for diving, is 106-feet (32-meters) long.  She dives the waters of Palau including the world-famous Blue Corner.


A word from Dom :  “The Rock Islands Aggressor is an old friend.  My first experience aboard her was in French Polynesia … and the next in Papua New Guinea.  I’m happy to say she’s found a stable home base here in Palau and while not in the luxury yacht class, she’s stable, spacious, comfortable. relaxed … and simply a great platform for divers … with all the Aggressor amenities!”….. Dominick Macan

Let’s start from the top and work our way down.  Palau Aggressor has a great, mostly covered 50-foot sundeck with tables & chairs and hammocks. From this area, stairs take you down to more outside tables & chairs and the bar & bbq at the aft of the upper deck.  This deck also houses an interior salon with TV, stereo player, movies & books as well as comfy sofas …. and the interior dining room. All nine guest cabins are located on the main deck of the catamaran and due to this configuration on a catamaran, the cabins feature windows instead of portholes.  On the main deck, you also find the large dive deck and camera table. 

Delicious barbecues, American and local dishes are served. Most meals are served buffet-style.  Breakfast is cooked to order and is followed by a buffet lunch and a chef-prepared meal at dinner with tableside service.   Also included are fresh mid-morning and mid-afternoon snacks. For your entertainment there are shore excursions to cays and beaches (where available) and other activities include snorkeling and digital underwater photograhpy.

General itinerary information

Palau is a year round destination with something different as the seasons rotate.  December through March, you might see as many up to 30 mating manta rays!  More winter excitement happens in February and March with large schools of Moorish Idols, unicorn fish and several species of butterfly fish. Throughout the year you’ll find massive bait balls of scad at Ulong, German Channel and on the reefs of Blue Corner and Siaes Corner.   The areas between Palau’s mushroom-shaped rock islands offer a variety of exciting dives: shark-infested channels, blue holes, a few caves and some WWII wrecks,. There are sheer walls covered in luxuriant soft corals & big anemones.    If you love drift diving, you’ll get plenty here … flowing along with schooling sharks !  Most every itinerary will include Peleliu Corner, Blue Corner, German Channel and Ulong Channel as well as an excursion to the amazing Jellyfish Lake.
