Thanks for reply, John.
Understand the carbon mast stiffness, one thing you can`t do easily with aluminium unless it`s tapered. Maybe one day that technology will be possible way down south in Africa, but for now carbon masts are unaffordable for us.
We used to have stiffer alu masts than we now have, and also used to over-rotate with very loose diamonds, but now have softer alu masts and do the exact opposite.
Forgot to mention in my last posts - the Stealth looks really sweet at speed ! The boat looks larger than the 16ft that she is, must be the width & those tall bows.

Cheers
