1. The Cosmic Muffin

Designed By: Dave Drimmer 
What It’s Worth: $9 million*
Where It’s Docked: Fort Lauderdale, Florida 

According to its website, the Cosmic Muffin knows it’s not the “prettiest” boat in the harbor, but that doesn’t take away from its uniqueness. The Cosmic Muffin is the first watercraft to be constructed from the remains of a downed airplane. The boat’s hull is completely rebuilt, but much of it comes from recycled parts of Howard Hughes’ plane.

The Cosmic Muffin’s website says that it was “designed” to be reused, recycled, and recombined. The main goal of the boat is to promote less consumption of resources and to lessen the amount of garbage in the world’s landfills.
