You can find all of the maximum allowable measurements on the rules section in the racing link. These are for a 155% headsail. Every sail loft out there has these numbers an more for when you purchase a sail. Mauripro Sailing has a good supply of information regarding sail area and rig size as well.
a 155% std rig:
Luff - 30' (this number shouldn't change or vary only a few inches in any sail above 100%) LP - 16' 3.25"
Different schools of thought on this. My boat came with a single line looped through the clew in the middle on both headsails and they stay on the sails. The working jib sheet is a heavier line than the genoa sheet, largly because I replaced the genoa sheet myself using 3/8" line. I think the jib is 7/16" or 1/2". Others use 2 separate sheets tied to the clew with bowline knots. This makes it easier to use 1 set of sheets for all of your headsails and may make it easier/quicker to change headsails while under way. If using separate sheets, you want good rollers on the forward lower shrouds. I use 1.5" PVC pipe.
If you aren't racing then it really doesn't matter. I would say most people have 1 set of sheets.
Some people tie a loop knot on the end of 1 long sheet. Some put two sheets on with a bowline. I'm not a fan of the snap shackle, in my mind it beats the snot out of the deck and that is way too much weight for me to hang on my headsail.
From a safety standpoint, while underway, I prefer to keep headsail changes to a minimum and stay off the foredeck also as much as possible. I rig all headsails with their own sheet(s) and use a catspaw to attach to the clew. One line, doubled and the catspaw and the change of sail is done to minimum time. I echo the "no snap shackles" on the sheets. Mike
I do not recommend snap shackles, but I use them. I have taken one to the temple where my Titanium glasses took most of the impact, It was the fault of the skipper who was not handling the sheets well. I pride myself in not allowing those situations to happen on my boat but realistically that is just arrogance talking. I have always had lots of headsails and have always had very nice sheets, a $50 snap shackle solved many dilemma associated with that. I did leave a red 1/2" trophy braid on a storm sail once, it was a great arrangement. I have self tailing winches now and they are very picky about what line they will work with. In the final analysis it is ridiculous for me to use a snap shackle on a furling sail, I will probably remove it for the spring.
If we have to change headsails while awaiting a race or in between races, the snapshackle is a godsend, though I agree about it slapping around. Just undo it, unhank sail, hand sail and attach!
I use an aluminum carabiner from REI on the middle of my jib sheet. It is the kind that has a captive barrel that screws over the connection. It is super light, and won't beat you or the deck. Cost only $12.
Make sure to use the one with the screw barrel, before I did this I had a bad habit of cliping the carabiner on the shrouds during a tack.
Hmmm...we use a snap shackle on our 110 & 70 so the transition's easy in a blow. I hadn't thought much about it beaning someone, seems like you can keep tension on your leeward sheet till it's reattached, but maybe I need to think about it. I have lots of carabiners from when I used to climb, and I have several with the locking barrels. All the rest of our sails have their own sheets.
I looked through my photos and have only one that shows the sail, and not very well, but you may be able to get the idea of how good it is. If you could email me at l.montgomery@sasktel.net I will send you this picture by email.
I will be up to the cottage over Christmas and will take some photos and take some measurements for you.
