#sail performance

Does a full-batten mainsail actually outperform a traditional one in real-world conditions, or is it just marketing hype?

Is switching from a furling jib to a hank-on really worth the performance trade-off?

Is switching from a Dacron main to a laminated racing sail actually worth the premium for club racing?

Do you actually get better performance from a $5,000 sail, or is that just marketing for people who don't know how to trim?
