Rudders under Progress

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).

Rudder foils ready for sanding and a couple of paint-jobs.
The F18 daggerboards were to short so we’ve made them longer (purple part in the vacuum bag above).
