Some readers may remember the incredible-looking biodiesel-powered Earthrace trimaran. Originally designed to circumnavigate the world, it ended up being donated to the Sea Shepherd Society, and was promptly rammed and sunk by a Japanese whaling ship. Well, while we may no longer have it to gawk at, a one-off watercraft that could almost be considered its gigantic, luxurious sibling is currently being constructed in China. Behold, the Adastra.
