Measure Tip-to-Tip-to-Tip:
Whether you're measuring a headsail or a mainsail, we only need straight-line measurements between the tip of the head, the tack and the clew of your sail (see illustrations to right). Do not try to measure any curves in the sail. We will take care of making the proper adjustments when we build your sail. Before measuring, pull the sail hand tight.
