Winging Boat

Catamaran frame for stability – freely rotating wing working as a sail – ball joint connected rudder.
Rarely wind is pushing the sail and sailing upwind is possible with the lift created by the sail. But since we are not able to print a flexible fabric sail, we can print a wing instead.
Frame is the result of experimenting with some different modelling features and is a bit unusual looking.

Modelled with Autodesk Inventor 2014. Planned to enter this to the boat contest but lazy summer days made me miss the deadline. Unfortunately I have not printed this out. My first model for printing purposes, so be merciful. I tried to make the parts printable without supports.
With time I will revise the model and perhaps if the boat floats and sails ok, I will modify it to be included with a couple mini-servos, battery, radio receiver for an easy to control RC-boat.
