You are absolutely right. It takes some time from cruisers to adopt tools used by professional racers. However, we do have positive feedback from american cruisers that used DrSails to repair batten pockets in a main sail or repair a tear in an spinnaker.
On top of that, we are aware that more and more boats bring DrSails on board in races such as Transat, Transpac and Baja Haha, among others. In fact, Ullman sails and San Diego Marine exchange held an offshore sail repair seminar recently for the Baja Haha fleet. https://www.facebook.com/DrSails/pho...type=3&theater
