I recently posted about WHY, which was one of the cooler things I saw at last fall's Monaco Yacht Show. Here's another:

PMYers, meet Aeon, Feadship's 2009 concept yacht.

What, prey tell, is a concept yacht? According to the builder, it's a vessel "that infuses advanced design, technological and engineering insights with the lastest thinking on how upcoming generations of owners will enjoy life at sea." Each year, Feadship unveils a new concept model and for 2009, the idea was to envision the owner of 2020, identify what was most important to him or her, then design the boat of his or her dreams.

Feadship's designers agreed that above all, the yacht owner of 2020 will be extremely green. Thus Aeon, a boat that's all about the environment, sustainability, and, as Feadship puts it "creative conscience." While I can't help but think Swiss, the design was actually inspired by whale sharks—not cheese. ("The whale is one of the iconic symbols of the movement to raise environmental awareness," Feadship explains). Large sections of her exterior could be covered in solar paneling, and Aeon's propulsion would be entirely electric. She'd also feature cool elements like a large ocean observatory on her tank deck.
