Measuring for your New Sails

We do a lot of sail quotes – most of which are initially done based on standard rig dimensions from our extensive database of over 7000 boats. But if a customer wants to take the next step in ordering a new sail I always recommend a measurement of the boat. I make myself available to the customer to assist in this process – one of the real values that a local sailmaker can provide.  If you sailmaker does not provide this service you may want to shop around.

Case Study: I once sailed on a 25′ sloop which had just recently been upgraded with new racing sails of a nice laminate cloth. They held a good shape and flew nicely. The problem was, that in light air, the second batten would get hung up on the backstay. It would usually require help during a tack in light air – which is a real problem here in our light air summers, and not what you want your helmsman or crew worrying about each tack. These sails were ordered from an out of state sailmaker – with standard rig specs for the boat. It would appear they did not take what we call the BC measurement -  Backstay Clearance; which is measured from back of mast to backstay at boom level. There are other specific measurements that need to be taken that are not in the rig database – especially for headsails of different sizes and furling rigs.

Discuss your specific boat measurements with your local sailmaker – and ask for measurement forms if you are going to do it yourself.  For my customers I am always happy to make a visit to the boatyard or dock to assist – a job perk in my opinion.  Sailmaking is an art and a craft – make sure your sails fit like a tailors suit for your hard earned dollars!
