#POWER FROM THE SEA - Marine-based renewable energy projects could be introduced without a damaging impact on marine wildlife, according to a new briefing paper from Friends of the Earth.

Business Green reports on the paper from the environmental campaign group, written by marine ecologist Martin Attrill of Plymouth University's Marine Institute, which draws together research on the biodiversity impact of offshore wave energy, tidal energy and wind power schemes.

Attrill found that the deployment of sea energy arrays could ultimately benefit many marine species by reducing the effects of fishing activity, and even acting as reefs to attract new sea life.

He cites the example of a grey seal colony in Strangford Lough that has steered clear of a nearby tidal turbine over the three years of its operation in the lough.

However, Business Green says the report makes clear that the deployment of such projects "must be done sensitively", noting that any negative impact on biodiversity "would be significantly lower than the damage done to marine wildlife by rising sea levels caused by climate change".

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.
