Gregory's Server@neauoire Do you have a mount point further to the stern for heavier winds? Because it looks to me like it may be too far aft, making the angle between boom and preventer too sharp, which increases the load the preventer takes exponentially – like what happened during the Platino accident in NZ (excuse me if I'm mistaken, I have literally zero experience sailing, just passing on what I learned in training)
@lobidu that might be a trick of the picture because the preventer line does a pretty big arc. The preventer doesn't really have that much load, it never takes a jibe blow because it keeps the main tight in its place.
