I have a fairly decent quiver of boards n sails and my 2006 MS Pursuit 8.5 is my most used sail. (the one in my profile pic :-)
Barry Spanier of Maui Sails has called my sail "old" and yet it performs just fine.
Okay, the monofilm is slightly foggy, has creases, etc.

My bigger concern is the threading - especially around the 2nd batten from bottom.
One panel repair costs about $100 and a new sail like this around $600.
Also, since i do like cambers, perhaps an MS-2 or Titan 8.5 to replace ??

So, how long does one keep a monofilm sail that is used a lot ?
Does one replace the panels and seam re-enforcement each year on a most used sail or simply replace the sail after 4 years ? (sail was purchased in 2008)

thx for listening
