Hi Klaus,

I always think about wetted surface when the subject is daggerboards and rudders, so AR should be discussed as wetted AR. Thanks for pointing out the difference in how the term can be used

So first decide on the AR, then the chord and everything falls into the "best" slot afterwards by analysing the numbers?
I suppose there are physical limitations and non-achievable theorethical gains that also go into the analysis.


Sooo.. How do one decide on what AR to go for and the chord?
