The world‘s finest diving

Sea HunterExt1 opt786

Fabulous Sea Hunter has served Cocos since 1995 & is now ALSO serving as the mother ship for spring Silver Bank humpback whale trips.  She’s 115 feet & takes up to 20 guests in 10 cabins.

A word from Dom :  “Sea Hunter, known for her Cocos Island adventures, is one of the finest dive liveaboards anywhere. We rave about this vessel again & again. She is now working from January to April at the Silver Bank in the Dominican Republic, providing guests with marvelous, magical humpback whale trips which I can’t recommend highly enough !”  …  Dominick Macan

The top deck (bridge deck) features 2 large suites as well as a 1000 square-foot sun deck which doubles as an exterior dining room.  You can make yourself at home reading in a lounge chair or catching some rays, or get your mouth watering while the chefs use this area to prepare sumptuous BBQs.  The bow section of the Sea Hunter offers a spacious area for passengers to hang out, watch the dramatic sunsets.

On the main deck, you’ll find a cozy study with comfy seating, a library … plus TV, VCR, DVD and a personal computer to allow divers to view and edit their video and digital photography.  Mid-ship on this deck is the warm and welcoming formal dining room and adjacent to that an enormous, bright and airy lounge. There is also a variety of nightly entertainment available aboard. This includes slide shows, DVDs, videos, games and more.  Please feel free to bring along your own favorites. The refrigerator is constantly refreshed and brimming with soft drinks, beer and ice for your pleasure and something to munch on is always within reach.

At the stern end of the main deck is the well-designed dive deck with fantastic camera storage area and super-sized swim platform … and even a private dryer for your towels and swim suits.

The three daily meals are a delicious international mix with a local flair.  Breakfast (cooked to order), hearty buffet lunch and dinners are served daily in addition to fresh mid-morning and mid-afternoon snacks.  Beverages (including beer and wine) are complimentary while onboard.  If you have any special dietary requirements, please advise us as soon as possible.  Vegetarian and vegan meals are not a problem with prior notice.

Port of Embarkation: Cofresi, Puerto Plata, Dominican Republic

Sea Hunter docks at Ocean World Marina in the Cofresi beach area, a few miles west of Puerto Plata.  The closest international airport is Gregorio Luperon International Airport (airport code POP) with direct flights from Miami, New York, Charlotte and Boston as well as several European cities. It’s about 30 minutes by taxi, costing around $45-50 USD.  The M/V Sea Hunter departs each Saturday evening during the ten week winter season. The season runs from late January until early April. Guests board the vessel each Saturday at 5:00pm. It’s a good idea to arrive on the island at least a day or so before departure.
