Well, sailing and racing on San Francisco Bay has taken its toll and I’m looking at replacing my main and possibly the genoa. I am exploring the newer materials such as Doyle’s D4 Stratus cloth and UK’s Tape Drive. Doe anybody have any feed back on these materials? I am concentrating on the Tape Drive right now. How well do the load tapes hold up? I can get the tapes in either Carbon or Spectra and I was wondering if the Spectra will hold up better in the UV. But I’m also concerned that the Spectra load tapes would give me a sail that is marginally better than polyester (but at Tape Drive prices!). My boat is a Catalina 34, and besides cruising, I race YRA, One Design, Club and Single Handed events.
