Measuring your sails is easier than it sounds. Please, take a halyard, a tape measure and follow our measurement form guidance. You can send us your sails sizes using our measurement forms (please, download your form from this page) If you can, send us your boat's sail plan or designer's specifications and as many specifics about your boat and your new sail as possible. We are here to make exactly the sail you want. You can also send us your old sails by shuttle bag. In this case we'll take the sizes on your sail. For further information or if you have questions about which type or cut of sail is best for you, please kindly email us at firstname.lastname@example.org We'll do our best to give you a quick answer.
