Mast top extension
As we had bought a new main sail that had a bigger "rounding" in the
back, our back stay chafed on the sail always when the winds were weak.
This was a problem that a fellow Hanse owner had on his boat too so he
went to the drawing board and designed a new mast top extension that
would move the backstay 135 mm out from the top of the mast. This
eliminated the chafing to a certain level but not fully. In hindsight a
150 mm might been better.
The fitting is very easy
even if you do it like we did it, when the mast was on the boat. I still
recommend that you do it when the mast is off the boat so you do not
have to worry about falling tools and nuts. As the pictures are quite
self explanatory there will not be so much text to this subject.
