RE: Some questions about SJ23 sails

I have a SJ24, not a 23, but bearing that in mind, and the fact that all of
my sails are Milar/Pentex Laminates, not dacron, I find that if I keep my
sails flat, my 155% is good until it just starts to whitecap, about 12 mph
and yours should be about the same if it isn't blown out.  My 135% is good
to about 20mph, my 110% is good to about 25mph, and my 85% is good up to
about 40 mph if I set a single reef. 

Further, because the small main is so underpowered, I find that I can sail
comfortably under main alone in almost any blow.

there are many other members with much more experience on this list, but for

what it's worth...

I do find that my 150 is quite responsive, and I do only fly it in light 
conditions. It and the full main are quite impressive in 'ghosting' along 
with almost no discernible breeze. Overpowered, I've only experienced 
rounding up to windward.

Only time I used the second reef, along with the storm jib, I found I was 
making almost no headway, trying to beat into 4/5 foot waves. Shook out to 
single reef, bore off a bit, did much better. I do like the storm jib, makes

a big difference when under single reef in the main. In fact, I like it 
enough that it is my biggest reason in not, so far, getting into a roller 
furling system. I'm just not yet convinced that rolling up to a similar 
small size will have the same strength as the storm jib, on the other hand 
that's when I really hate going forward. Compromises...

Hope this helps, if nothing else it's fun to reflect on the boat!
