Was just looking around, and found 2 of these for sale in my city. I thought the price was quite redicules compared to what you get in terms of size etc, $507 575. Not sure why someone would buy it, sure a mobile home is pretty cool in some ways I guess, but it's not like you will be able to move it anywhere fast by sea ;P
Distance to the sea 9 meters (you don't say)
Monthly costs - $1748/month
Broadband, TV, Telephone - $58, 100 mbit, 18 tv channels, telephone.
