Good question. When I have the main up and reefed, I always use my working/110 jib and not my Genoa. So, with roller reefing on the jib, I just roll it in as far as I need to, perhaps leaving a little to help with tacking. But I am just doing day sailing these days, so never very far from the marina, if it gets really wild.When you are using your first reef, how often do you find yourself thinking, "That's still a little too much sail"?

Re: Genoa only sailing
Just to say: I guess in the factory main the reef would be to say a second reef. So in the factory main there is no "reef 1".

Re: Genoa only sailing
Reef points are usually set at a percentage of the luff length. On an "X" the luff is 25'.
Single reefs are usually set 15% of the luff from the bottom (3' 8"). That is somewhere between a 1st and a second reef depending on the sailmaker.
Sails with two reefs are usually set up around 12% for 1st (3') and 24% for 2nd (6') or 15% for 1st (3'8") and 32% for 2nd (8').
Sails with three reefs are usually 11%, 23%, and 38%.
The best I can tell from measuring my rolled up Mack main mine* are pretty close to the 12% and 24% numbers. That makes my sail area around 79% on the first reef and 63% on the second. A third, if I ever get one, would make it around 50%.
My trig may be a little rusty so feel free to check my calculations if they matter to you. I leave square head sails and accounting for the sail draft as an exercise for the student.
*If "alliteration always annoys", does accidental alliteration accidentally annoy?

Re: Genoa only sailing
Well, hopefully my bat nesting issue is over. With BeFree's help, I changed my headsail back to the working jib, and we bent on my mainsail, so I am a "proper" sailboat again. We'll see how things work out with the bats. I do have another issue that might impact this decision. My right knee is a little "dodgy" these days. That makes getting up on and down from the cabin top to untie/tie the sail ties before hoisting the main sail a bit of a challenge. I am thinking about how to attach an adjustable cane to the midships port stanchion to see if it would help hoping it wouldn't fowl the main sheet on a broad reach. Stay tuned; don't think this thread is finished, yet.

My left knee is dodgy too (retired airborne ranger). I have a knee brace. Works pretty well.
