A member on a dutch forum I follow is going to attempt to build an offshore exploration vessel. Which in itself isn't difficult, but the engineering he is going to try is. The finished ship will have full dynamic positioning via a gps system and once he programs in a course for it to follow, all he has to do is launch it, no radio control!
The engineering comes in the form of what can be seen in the photo of the full size craft, it has 2 at the stern and 2 at the bow. He intends to make all the props work, so its going to be some feat of engineering.
