Re: New sail Dacron characteristics

If you are thinking that the Dacron will stretch a bit during the breaking in period, then not so much afterwards, I’m afraid that this is not the case. It will stretch according to the load you place on it. That it is why it is always a good idea to loosen the outhaul on the main and halyard on the furling jib so not to make the stretch permanent. Remember that woven cloth has warp and weave directions and the sailmaker in using his panel cutting techniques will try and get the two to stretch at the same rate. The biggest sin you can do is motor while the main is up and fluttering. “Motor boating” is music to a sailmaker’s ears. If you are thinking about racing the sail, sail with it the fewest amount of times as you can (use the old sails to deliver the boat). All sails start stretching the day you fist use them and stop the day you throw them into the dumpster.
