The stock Hobie sails are made from 5.6 oz cloth. The 5.6 oz cloth we use is from one of the best textile companies in the World, Tejin. It is good stuff. We have spent many years trying for better, more durable sail materials and feel now that the sails are the best they have ever been. The stock sails include teflon luff tape to make hoisting easier. Heavy duty stainless head grommets with INOX rings. Stainless reinforcements in the jib clew plate holes and many more features you will not get from another sail maker.
In short. Hobie Cat makes the best sails available for a Hobie 16.
You may not want to race your boat, but think of two things... Durability of the stock sails and Resale value with race legal sails.
