We eliminated all antenna mounts and brackets that were used to penetrate the old membrane and designed mounts on a new railing system. Railings were made in only 3 sections and machined sleeves were used at the 2 intersections. Instead of canvas we decided to go with aluminum plate. Each mounted with 6 machine screws into tabs on the railings. For the A/C units we used perferated aluminum. We also integrated flag holders on our SkipperLiner.
