We upgraded our 28 with a roller furling, you will want a good sailmaker who knows this boat, the sail needs to compensate for the sag in the head stay that this boat has. I would suggest getting a 135 roller furling, 135 can be reduced to a 100 where a 150 can only be effectly reduced to a 120 (for up wind work). If you do not have the roller furling yet consider a better option, a reefable 150 to a 120 with hanks. Permanently mount this sail, for a #3/4 get one and host over the top of the pulled down 1. This way you can have a verstle sail plan without the limitations of a roller furling. We can not store our roller furling nicely when we race and the sail limits out weather work in performance. We are on LIS, an area that needs a boat to point if your going to get somewhere. These are just thoughts, you may be perfectly happy with a roler furler. I am an avid racer with no racing boat so I do the best I can with what I have. The performance of a well cut hanked on sail is far superior to the rollerfurling across the broad range of conditions. And it doesn't have to take up our saloon to store sails.
