MakeItFloat Boat-Rig

Hi Folk
i like challenges, so i decided to join the S.T.E.A.M. - MakeItFloat 
This is my first challenge thingiverse. So I started with my colleague to find a good mix of real solutions for transport of heavy Wight. We found something. This is the first concept or our total 3 ideas for this challenge. Hopefully we have enough time to generate, print and test all 3 concepts.
Focus on this Concept:
1. Print less parts and support structures as possible
2. Carry heavy load -> 2 Euro coin
