thinking about using one of those low friction rings (aka ferrules) as an attachment point for trimaran netting. This would be at a mid beam net corner on the front beam. The rest of the attachment system will be the venerable rod in tube.
I would glue the ring into a piece of HD foam with GFLEX, and then lock it in place with uni carbon.
My question is whether I need to isolate the ring with a layer of glass to avoid galvanic reaction between the ring and the carbon.
