The rudder systems of proas are always debated. For many proa projects the rudders, cruicial for safety, were the weak spot of otherwise neat designs. The challenge is to design a system that works in both directions of travel due to the nature of the proa: Shunting.
We hope to have found a robust and cheap way that allows us to keep proasis on course comfortably and safe. Our proa will get recycled F18 daggerboards as rudder foils, mounted in kick-up cassettes on each beam (more about the cassettes in later posts).
