Measuring your sails is easier than it sounds. Our team is here to make the sail measurement simple and stress-free. So let’s get started. Please, choose a fine, not too windy day to take your measurements. Take a halyard, a tape measure and follow our measurement form guidance (download your form from this page and add all comments you may have). A reel type tape measure has a loop of some kind at the end which is easy to attach to the halyard. Always pull the tape measure tight. If you can, send us pictures, your boat's sail plan or designer's specifications. It is better to physically measure the boat and not rely totally on manufacturers specifications. Rig sizes can vary even between the same make and size sailboat. Measurements can also be altered as a result of re rigging. Good tip: Remember to tie a line to the halyard along with the tape measure in case your tape breaks, you can retrieve the halyard.
Hook a tape measure up to your headsail halyard or to the upper furling swivel on a furler, just like the head of the sail. Hoist it until it stops at the top. Measure down to the tack fitting for Lp. Make sure the tack shackle is pointing up, as it will do when the sail is set. Measure the horizontal distance between the tack fitting and the mast for J. You need to check the diameter of the lufftape, colour of UV cover, to be placed on either port- or starboard side. Measure the position of both ends of the sheeting track on deck, for perfect angle to the clew of the new sail. Please, note the height of the clew in case you need high-cut clew sail for a less obstructed view to ahead and to leeward.
