I’ve been keeping my eye for a while now, looking for a sail smaller than 4.2. My current wave-ish sails are 4.2, 4.6 and 5.0. All sailworks revolutions from 2008 that I picked up a couple of years ago for peanuts. I may end paying a reasonable amount for a smaller sail because of availability and because I’ll have to get a mast too, probably along with a RDM mast extension, so I want to make sure I get the right size. I haven’t been out a lot this fall/winter because of work but it seems to me that 4.5 is pretty popular for people that are maybe 20-30 lbs heavier than me.
A few weeks ago I would have thought 3.7 would be good for me, and as my older sails get replaced I could go 3.7, 4.5, 5.0. With a 3.5, I think it would be 3.5, 4.2, 5.0. The way things have gone the past week or two, I wonder if something even smaller would get the most use.
I also have a 1993 3.3 Revolution. I feel like it has a pretty small wind window, I felt I went from underpowered to overpowered really quickly. I don’t know if this is the nature of small sails, nature of the older design, or my skill level.
