Hi B J,

The use of “fairness” in the article is meant in the general sense—ensuring all boats get the same sails. It’s not about poor sportsmanship, but rather a way to remove a variable on the race course. One Design rules do allow a small window for measurements, so a different sailmaker might have a slightly different design. Plus differences in materials, and the age and condition of the sails adds another element. By supplying sails for the entire fleet at once, it keeps things fair for everyone.

On the silicone idea, I’ve never heard of it being used on stitching for aerodynamic reasons, and I don’t think it would make a measurable difference. Modern stitching is already very fine and doesn’t disturb the airflow in a meaningful way. If anything, adding silicone might create more texture than it removes, so any gains would likely be negligible.

Best,
Heather
