I have a new Dacron 6.3oz, full batten mainsail mis measured for my (non) Catalina 34. I'm told it is a close fit to Catalina 34's so this may be a good fit (and deal) for someone in your fleet. The foot measures 11' 7" (loose footed). The luff measures 38' 5". It also includes two reef points . included, but less desired will be a Green Sabre "S", number 34 and a hull number. Over $2400 invested. :cry4` Make an offer. Located at my home in Central NJ. Can email photo's.
