Name: Moka
Value: $25 million*

Actor Jerry Seinfeld is the owner of Moka, a charter yacht that has gotten a lot of commendations from RINA for being “Green Plus” and eco-friendly. Moka is, according to the website, built for “adventure.”

Moka is unique because she is able to remain anchored at bay without having to use generators for long periods of time. Moka has low emissions, low vibration, and low noise. He outfitted Moka with five cabins. She can house up to ten guests, not including crew.

It’s environmentally friendly status might not do much to offset Seinfeld’s enormous car collection though. The actor, who was on the -owned show Seinfeld, has a net worth of nearly $1 billion, and a car collection envied even by Jay Leno.
