Sailrite may list them as such, but I don't believe that I could get a 27' luff tight on my original equipment. And if one has a bimini, one might want even shorter than the 25'6" that my original sail's luff. Alberg was well known for having LOTS of sail area and I find that in most enjoyable conditions that a bit less main makes for a more balanced helm. With one reef and a working jib I can leave the helm of Chalupa and go below to mix another adult beverage. Granted, since I drink straight bourbon, mixing does not take long, but she will stail on a beam reach all day under those sails. I believe that most of the sail making sites are really listing for Pearson 26's, not for Pearson Aerials. Later 26's has longer masts.
