Over the years I have seen furlers bend to include the plastic and metal. The key is good tuning and when the forestay is loose to allow that bending, the rest of the rig is also affected.
If the CDI fails for the oriingal owner, geneally parts are replaced at no charge. Not sure about today but that will depend on the circumstances. I remember one time when the furler was being uncoiled, my employee said it was cut in two. Warranty, heck no. Upon visual and close inspection, the new employee took a hack saw and cut it. One thing with my employees, if a mistake was made, I showed them the proper way but when they lied, well you can guess how long they remained with me. When I knew I had to close, they were given a 6 months notice so they could start looking for a job and I paid them 6 months severance. The hardest decision for me was the fact I had to let family go.
