Hi Bill, I agree that sailmakers should play a bigger role in preventing Appendix G1.2 violations by guiding customers toward properly contrasting sail numbers on new sails. That said, part of the issue arises when boats transition from cruising to racing—whether through a new owner or a shift in interest—where aesthetics were originally prioritized over visibility. Older sails also contribute to the problem. In these cases, the contrast issue isn’t intentional but becomes a challenge later. Stronger recommendations from sailmakers would help, but ultimately, it’s up to owners to ensure their numbers comply. Hopefully, articles like this empower sailors to make informed decisions about sail numbers with a clearer understanding of the rules and their impact.

Hi Shannon, I hear your point and completely agree. Unless sail numbers are a very dark grey on white, they can be difficult to read—especially as they fade over time due to UV exposure. This is something more sailmakers should proactively address with customers, taking time and explaining why high-contrast numbers are essential for visibility.
