Carsten,
Congrats, what a achievement!
Impressive Boat, Fine craftsmanship, great project management ! You keep the hope alive that biggies CAN be done.
Any news from "authorities" administration etc... now as you close in to the "finish line" somebody just must call for "stopping this guy" - before the boat touches water.
If this comes up what is your "neutralisation tactics". Want to share a few thoughts on that?
