As usual Mangusta have designed a bigger boat by pressing the resize button on a picture of a smaller Mangusta. From 80 foot to 165 foot they look almost identical, just the scale is different. Its a policy I actually quite like. I saw the 165 at Cannes and its so huge, you have to look twice to make sure you've seen it properly.
I have a photo which illustrates the point, but i'm on the boat and can't load them from here, so will do in a few days.
