I have given up sailing until I can wear a trapeze harness which doesn't cause lower back pain by compressing my spine and hips. All current harness seem to use flexible materials which put compression forces on the trunk and abdomen even with spreader bars. Are there any harnesses with wide rigid back plates to spread the weight and ease pressure points? Or should I get a sailmaker to do a custom job to try to sort out my problems? There are rigid formed bosuns seats online. Has anyone used them for comfortable trapping? I don't want to reinvent the wheel if there is a real back supporting harness already out there. Suggestions?
