Genoa sheet length

[carry-on]

Old question, asked by Citroen/Dave last fall but not answered.
Have a 155 , hank on, genoa on order. The specs for the CP 16 say the jib sheet is 55 ft. Seems too long even if divided by two.
Maybe that length is for a furler?
Don't want a cockpit full of jib sheets.
What length do you use on your 155?
Thanks

You don't really have to measure them.  They need to be long enough to let the sail flog from any point of sail.  As long as you can take all the power out of the sail, that is all that is needed.  If you are worried about buying extra rope which can be expensive, use a length of clothes line to get a close guesstimate.

Carry-On,

My 1990 C16/III came with three new sails from Doyle, including a hanked-on 155 genoa.  The sheet length on it is 56'.  I don't have it on the boat yet so I can't say if that's excessive or not.  Fortunately, you can always shorten it.

Always go long then cut them back as you see fit.  You may find you'll want to handle the sheet while sitting to windward, and possibly tie off to windward so you don't have to move alee in strong winds.  That'll cause a roundup and those aren't too much.

What kind of track or cleat are you going with? Sheet routing makes a difference in line length too.

Check out the other post about the soft sheet shackle. Maybe get another another foot of line for that?

Thanks to all for the info. I think the 50 ft. clothes line will be a good way to start.
I plan to use 8mm line , it is good to be close on the length before buying. I am thinking about 40-45 feet/2 will do. The sheets will be outside the shrouds. I have a 120 jib with sheeting inside the shrouds. Anything larger could interfere with the spreaders.
I have not installed tracks at this point, so the sheet will go to a stern cleat and I will use a barber hauler or other method to work the sheeting angle.
I think 18-24 inch tracks will do if I get the best position on the combing. I sit forward near the cabin in most winds so I would like to keep the combing clear in that area.
