This paper describes the design of marine current turbine blades based on the results of a fully-aligned lifting line optimization model. The geometry is generated by assuming chord and camber distributions in order to reproduce a given loading on the turbine blade. This geometry is then analyzed with two three-dimensional potential flow solvers: a low-order panel code and a vortex lattice model. Accuracy and stability for different discretization schemes is studied, as well as the effect of different wake alignment strategies.
