After nearly 10 years my sailpack system is on its last legs. Needs replacement zip and stitching in several places. Decision made to replace. Advice needed - the existing has always been "oversized and baggy and apart from the sail head section could pack nearly double the volume of sail. It is the Bavaria factory fitted system. Now the crunch . Need suggestions on price and supplier and also owners with similar setup. Anyone have replacement made up from original template? Can probably use existing batten although snapped at one end!!
