Groundbreaking system to prevent collisions between whales and sea-craft

An unlucky passenger who died when a high-speed ferry rammed into a sperm whale in the Canary islands was the world’s first known victim of a new form of pollution – ocean noise. In places where marine traffic is heavy, vessels fast and whale numbers expanding, violent encounters are increasingly common. The cause of the accident, says marine biologist and Rolex Awards for Enterprise Laureate Michel André, most probably lay in damage to the whale’s sensitive hearing apparatus caused by the rising roar of man-made noise throughout the oceans. The whale was stone deaf – and simply didn’t hear the ferry coming in time to avoid it. Julian Cribb reports. Read More

Quiet cruising: Kayacht's electric powered kayak kit

By - February 5, 2008 6 Pictures
We've seen some exciting examples of motorized kayaks in the past including Surfango's 9.5hp, 25mph PowerKayak, but when speed isn't the primary objective, the electric option offers some key benefits over combustion engine designs - it's low maintenance, cost-effective, non-polluting and best of all it doesn't destroy the peace and tranquility of being on the water the way a 4-stroke does, making it ideal for pursuits such as birdwatching, fishing or photography. Kayacht offer an electric-propulsion solution that will bring these benefits to almost any existing kayak hull. Using a short shaft 30 lb thrust Minnkota motor with 5-speed forward and 3-speed reverse, the add-on system delivers a leisurely 5-6mph cruising speed for around 45 minutes, or for several hours at slower speeds or when using the paddle assist mode.
