Windward Islands Northbound and Southbound SEA Combo

Explore St Lucia, St Vincent, the many islands of the Grenadines, and Grenada for 44 days!

Fascinated with the tropical reefs and marine creatures or interested in a career in the marine sciences?  S.E.A. (Service, Education and Adventure) Voyages are a unique opportunity to earn environmental service hours and academic credit while adventuring throughout the amazing Windward Islands archipelago.  S.E.A. voyages offer you a great opportunity to learn about marine biology, sailing, and SCUBA diving, and make the most of your summer on a rewarding and educational adventure of a lifetime!

SERVICE These voyages focus on coral reef related environmental service throughout the Windward Islands.  Working with the marine parks and international monitoring organizations, we conduct surveys on wild dolphin populations in St Lucia, coral health assessments in St. Lucia's Marine Park, coral reef fish counts and project Reef Check in St. Vincent, and assist sea turtle population rehabilitation efforts in Bequia.

EDUCATION Coral reef biology and ecology accredited education programs. Discover the deeply interconnected ways the coral, invertebrates, and fishes work together in amazing efficiency.  Aboard your vessel are microscopes and lab equipment and a staff of enthusiastic marine biologists ready to teach you how to collect scientifically sound ecological data as you explore your interest in a science career or just enjoy learning about the unique aspects of the reefs creatures.  Learn to identify the top 25 corals and their common ailments as well as over 100 reef fishes in preparation for conducting biodiversity surveys of the reefs for the Reef Check initiative and add to the project REEF database.  During this process you will learn about coral aggression, learn to treat coral Black Band disease, and discover the different coral growth forms.  The behaviors of coral reef fishes are as vivid as their colors, and you will learn about their unique methods of mate selection and attraction, avoiding predation, and finding and obtaining dinner. A big part of the protection of these beautiful coral reef communities is through the conservation efforts of the marine parks of the islands. The marine parks provide safe havens from the effects of fishing and commercial utilization of the reef's resources, but the park systems are limited in scope due to economic challenges of the islands. We assist the local marine park rangers to conduct surveys assessing the health of the reefs and compare survey results to those taken outside of the marine park protected zones. You develop your skills in implementing the accepted protocols and methods of conducting field surveys to assess the health of fish, coral, and dolphin populations. All educational programs are taught in a hands-on approach in which you gain knowledge by doing, seeing and experiencing.

ADVENTURE Sailing throughout the archipelago, diving the coral walls, pinnacles, and reefs, exploring shipwrecks, hiking through the rainforest jungles, exploring volcanoes, refreshing in hot spring waterfalls and experiencing the culture and beauty ashore is sure to satisfy the explorer within you.  With lots of SCUBA diving included, you can earn multiple PADI SCUBA certifications including Advanced, our distinctive Research Diver plus Night Diver and Underwater Photography. We live aboard sailing catamarans and sail the blue passages between the islands.  You are the crew, learning to raise and lower the sails, navigate, be the helmsman, and drop the anchor all in time for volleyball, wakeboarding, and kayaking.

Days 1-4

Arrive into beautiful St Lucia and journey along a windy mountain road to the incredible Marigot Bay, our home port, where you climb aboard your 46 foot catamaran and meet your crewmembers. Learn how to sail your boat and set the lines off the dock. Do a quick check out dive and then get ready for some high voltage drift dives underneath the Pitons in the Soufriere Marine park. Dives like Supermans Flight and Coral Gardens will really excite your senses as you dive along steep walls with the current. Later, climb up to a hot spring waterfall and through jungle covered peaks of the Piton's, which are two conical peaks rising 2600 stright up from the sea.

Days 5-8

Have an exciting open-water sailing passage to St Vincent, where along the way we have had a pod of Killer Whales join us for the passage, swimming alongside the vessel like very large, playful dolphins. Upon arrive, hike up to the Falls of Baleen and enjoy a breathtaking waterfall view, swim with freshwater eels, and wonder of the beauty of the cool water rushing off the tall Soufriere volcano. Take a day hike to the rim of the volcanoes caldera and experience the primordial Earth.

Investigate bioluminescence during night dives and witness the changing of the guard of the reef fishes from the diurnal herbivores to the nocturnal predators as we dive some of the worlds best reefs.  Learn a bit about digital underwater photography as we continue our investigations in marine biology.

Days 12-15

We are working on our specialty certifications, including night, underwater photography, and wreck diver, and finishing up our Advanced certification, so that we can begin Rescue diver training. The beaches of Beautiful Mustique are a fantastic place to practice egresses and check out any stars walking by.
