I have an idea that I would appreciate some advice on. I would like to try to make a catamaran that can switch between a foiling and a non-foiling mode. I've tried to depict my idea in the image below:
The idea is to have the foils able to rotate on an axis that is inclined relative to the hull. When the foils are vertical they are aligned with the direction of the boat (angle of attack = 0), essentially acting as dagger boards; when they are rotated the angle of attack increases and can be adjusted as required, thus able to act as foils.
Does this idea make sense? If so, what would be a suitable choice of airfoil (ie. one that would be suitable as a dagger board in the vertical position)?
