Ben is right,
The guy probably has some good Programming skills and Hi-Jacked the unsuspecting guy's e-bay account.
Here is the scam.
Thjis guy wants you to e-mail him and he will make you a deal for like $6k for the boat. all you have to do is wire him the money. He will not take paypal or anyother thing. He will say the boat is available as soon as you pay via wire transfer or through a fake Square Trade Acct..
You own a boat that does not exsist and your out $6k. And buy the way this guy is in Amsterdam or someplace running this whole scam.
If it looks , smells, and tastes like "SHAT" , it is!!!!
