The original mizzen I fitted was 15 sq ft and it could create issues in gusty conditions but the helm only changed marginally. I then reduced it to 10sq ft and the helm is very close to being without it as designed. It's a great help heaving too and that hasn't changed with the reduction in area. Hope that answers your question ok.
@@iankirk-r9d Thanks for the feedback Ian I agree with you that a mizzen on a small boat is quite useful. I have considered fitting one but had concerns regarding balance. Based on your experience I think that it is worth having a go.
