Visby plans

Good evening everyone,

A friend of mine in Task Force 72 (http://www.taskforce72.org) is looking to build a 1:72 scale radio controlled Visby class corvette, however good plans (or even bad ones) seem hard to come by.

Does anyone have a set of plans, particularly those showing the below water contours?

Any help, even a link to a retailer or plans supplier, woud be very greatly appreciated.

Thanks
