Congrats NavyPT, hope the survey
works out. I'm with Kevin - if you can get a 130% with a foam (or rope) luff that enables the sail to maintain proper shape when reefed, you will be well served. Some (including myself) still believe that a 130 does not make a good storm jib
when heavily reefed due to its construction and design (lighter dacron/seams/stitching/different shape/lower clew than on a dedicated storm sail), but it should prove quite adequate for sailng on the Chesepeake so long as you are reasonably prudent.
If you are buying
new, there may be some manufacturer/s that produce and stock genoas for the Catalina
27; if so, they should be cheaper than a custom ordered sail. Considering the price/vintage of your boat and the number that were produced, you may also be able to locate a decent used one online.
