I started this project this summer. It's a model of the Russian Nuclear Icebreaker Lenin. Originally I was going to use cupper as the skin but I had difficulty fixing it to the rib so I decided to take the easy way out and use fiberglass. The ship will be a robot in the sense that it will have DP 2nd class. What this means is that it will be radio controlled with the ability to hold position and move to specified co-ordinates while holding the desired heading just like a real ship would. The position will be held using a compass, GPS, and either a laser or sonar. I might take it one more step and also set up a taut wire.
