Update.. UMT sent me a quote for the 110 Sport. I called them and said that I had a 11 Classic, not the Sport. Juan told me to send in the measurements so that theycan build them. I asked about the chances of the welded ring breaking and he said that they would replce the sling if that happened. Wouldn't comment on possible damage to the dinghy or the mother vessel. Think that I'll just use a quality shackle and just leave the ring dangle!
