Logging Sub Makes Short Work Of Underwater Forests

Anyone who thought that Thunderbird 4 was the best ever underwater craft might have to have a rethink after seeing the Sawfish.  Designed for underwater logging, the 7000lb remotely-operated craft was developed by Triton Logging and can harvest up to fifty trees in each dive, sending them floating to the surface via reusable inflatable airbags.

Powered by a 40-75HP electric motor that uses biodegradable and vegetable oil-based hydraulic fluids, a combination of eight video cameras and a sonar system allows the operator to use the Sawfish's 55-inch chainsaw to make short work of underwater forests.  I think it has the potential to be this Christmas' bath-toy.
