I need to limit mast rotation going upwind, I also don't have a problem needing to over rotate the mast downwind since I run a spinn. Good idea on not riveting, looking closer at the piece from Murrays I see it has a 1/4'' hole for NACRA, so a 1/4'' through bolt should work well.
The Dart 18 use a line from the main clew to the mast spanner. A little crude, but works.
Does that work?
