Re: Batten Replacements?
Full length battens are costly, but the short battens found in many boats are very affordable. You may not notice the difference as a newbie/non-racer, especially with older, stretched ("blown-out") sails, but battens help keep a smooth trailing edge shape to your sails. This not only provides for better airflow (less turbulence), but also minimizes the flutter in your leech, thereby extending the life of your sail.
The only "cons" I can think of is that they are not free and that you need to assure they are properly captured in the batten pocket.
