Les récifs coralliens d’Europa

The Antsiva is a 28 m motor-sailing yacht with cruising speeds of 6-8 knots, and berth space for 8 comfortably and up to 11. With her Captain and owners, Nico and Anne, she has been based at Nosy Be in NW Madagascar for over 12 years, and has sailed the waters around northern Madagascar, Mayotte and the Comoros, with longer forays into the Iles Eparses in the Mozambique Channel and to Bazaruto, and the Seychelles. The Antsiva is fully kitted out for diving with over 20 SCUBA tanks, two compressors, and dinghies, and its internal living space is also well-designed for computer-based work for recording data and photos. Wet-lab space for collections is on the upper decks, so is vulnerable to severe weather (fierce sun or rain). Hold-space is ample for samples and equipment. With a water-maker and full electrics Antsiva is well suited for long trips.

Antsiva fills a much-needed niche for coral reef-oriented field research. I’ve been on her 3 times, and found that her combination of amenities and the experience and interest of her crew is perfect for coral reef survey expeditions. With a full gamut of new technologies (auto-pilot linked to charts/mapping software, weather satellite downlinks, etc.) and Nico’s experience in the region and with the boat, the Antsiva is able to get to shallow and sheltered areas not accessible to larger vessels, or where Captains of institutional research vessels would never dare to try. The logistics of getting divers and equipment onto and off the dinghies, and to dive sites twice and in some cases three times a day are well-worked out, and Antsiva makes the most of opportunities by moving the yacht to the closest place possible to reduce long dinghy rides. The engineer/dinghy operator and compressor operator/yacht-hand make operations easy, and leave the scientists free to deal with their main work. I know of many other research trips that have used the vessel (sediment sampling, birds/turtles on remote islands) and highly recommend it, so Antsiva clearly has a good sense of satisfying the needs of research operations.

On top of this, the food and ambiance are fantastic and relaxed, with a French flair. The boat operates in French (and Swahili with Said, the yacht-hand!), so having one fully francophone team member will be important for the logistics of a cruise. While she has focused in the NW and SW parts of the Mozambique channel there is no reason for Antsiva not to go farther afield, and she may become one of the principle expedition vessels used more broadly in the WIO.

I have been studying coral reefs in the western Indian Ocean and in the Red Sea for just on three decades. This has entailed working and living on boats as varied as small fishing craft in Mozambique, Eritrea and Madagascar, to large supply ships and research vessels. Amongst these, I have had the pleasure of undertaking soft coral surveys during five expeditions to the French Scattered Islands on the Antsiva. Nothing has matched the Antsiva for comfort, efficiency and safety. The craft is beautifully designed and appointed as a research yacht and is fully equipped with all the requisites for SCUBA diving on shallow coral reefs: a raisable keel, more than enough SCUBA cylinders, two compressors and the small boats needed to access the reefs. Furthermore, Nico and Ann Tisné run an excellent operation with their crew. The cuisine is excellent, the cabins are comfortable and one is secure at all times. The atmosphere is so convivial that we have become enduring friends. This is a safe platform which I can highly recommend for reef research.
