#MarineWildlife - The Irish Whale and Dolphin Group (IWDG) is marking 20 years of researching the dolphins of the Shannon Estuary.

As the IWDG's Dr Simon Berrow relates, it was not an auspicious start on 2 May 1993 when the first research trip on the estuary returned after five hours without having seen a single cetacean.

But the following day brought a bounty, with 16 dolphins across three different groups located by the IWDG - the beginning of two decades of sightings and recordings for the Shannon Dolphin Project, which has identified around 230 individual dolphins to date.

Thanks to that project, we know today that at least six of those dolphins first seen in 1993 are still in the estuary as of last year.

The Shannon Dolphin Project now has a website explaining its achievements and the work of the Shannon Dolphin and Wildlife Foundation (SDWF) over the years.

Meanwhile, Afloat reader Karl Grabe has also produced a spectrogram and edit of hydrophone recordings captured by Dr Berrow of Shannon dolphins just a few weeks ago.

Grabe previously uploaded a wonderful snippet of dolphins vocalising in the estuary late last year.

The Dragon was designed by Johan Anker in 1929 as an entry for a competition run by the Royal Yacht Club of Gothenburg, to find a small keel-boat that could be used for simple weekend cruising among the islands and fjords of the Scandinavian seaboard. The original design had two berths and was ideally suited for cruising in his home waters of Norway. The boat quickly attracted owners and within ten years it had spread all over Europe.

The Dragon's long keel and elegant metre-boat lines remain unchanged, but today Dragons are constructed using the latest technology to make the boat durable and easy to maintain. GRP is the most popular material, but both new and old wooden boats regularly win major competitions while looking as beautiful as any craft afloat. Exotic materials are banned throughout the boat, and strict rules are applied to all areas of construction to avoid sacrificing value for a fractional increase in speed.

The key to the Dragon's enduring appeal lies in the careful development of its rig. Its well-balanced sail plan makes boat handling easy for lightweights, while a controlled process of development has produced one of the most flexible and controllable rigs of any racing boat.
