Are laminate sails worth upgrading to from regular Dacron sails? Yes, in some cases, in others, no. The main difference between a Dacron and a laminate sail is in the shape of your sails when you tack and how this impacts on the performance of the maneuver. The price point also has to feel right for you. If there is a large difference in price between Dacron and laminate sails, then a set of high-quality Dacron sails are still going to satisfy your needs for the long term. It all depends on what you are trying to get out of your boat and which sails you will need to accomplish those goals.
