Doyle Makes two versions of the StackPack. Not trying to advertise, Just trying to help clear things up. It sounds as though, without seeing it, that your boat may have the economy version we call the Cradle Cover. The True StackPack is physically attached to the sail, and includes what we call the Integral Membrane. When the sail is raised, this membrane pulls the cover up tight against the sail to maintain the sails aerodynamics, and inturn keeps the cover from Flapping, and allows the lazyjacks to go slack while sailing. The Economy version, Cradle Cover, is independent of the sail and does not have the Integral Membrane. However, both systems utilize an additional cover piece that goes around the mast to close up the front of the cover system. Since its inception in the mid 80's, we have supplied over 15,000 StackPacks and/or Cradle Covers to customers. To be perfectly honest, as with any system, not everyone finds it to be the perfect solution to their mainsail handling needs, but at the same time we have many repeat StackPack customers, and have supplied virtually all Moorings charter boats with one of these systems.
