My brother and I are new to sailing. We just bought a Hunter 31 (yesterday) and I have learned so much from this site in such a short time. THANKS TO ALL!!! Can someone please tell me the difference between a jib and a genoa? Thanks! Rob *0

Well, A Genoa Is A Type Of Jib
I guess strictly speaking that the jib is the sail set in front of a sloop's mast and does not overlap the mast (a 100%). A genoa is one that does overlap the mast (a 110, 120, 130, etc.) Technically, I believe the genoa is a 'genoa jib'. I sure wish there was one of these forums when I started sailing! RD

Rob, IMHO I think Rick is pretty close...
although our H28 had a 110 jib, part of it has to do with how the head sail is cut. Jibs tend to have high cut clews, whereas genoas tend to have low cut clews, also called deck sweepers. Terry

Rob, cool boat, especially for a newbie.
Welcome. A thought, get yourself a copy of Chapman's. It'll really help with the learning curve. And it really helps with the 'proper' names to use and why they should be used. The terminology was developed because of safety requirements at sea. Again, welcome. But someone who wants to learn, is always welcome.

Terry, I'm hardy a newbie but I'd have to break
open Chapmans for that one. Anybody know the dividing line? I just assumed it was more than 100% to be a Genoa but some distant memory says the headsail would need to be closer to 150%.

Can I muddy the water?
I've read two definitions computing headsail percentage. 1. Actual headsail area as a percentage of foretriangle area. 2. LP (luff perpendicular) length as a percentage of J measurement. If either of these definitions is correct then actual overlap won't be directly tied to the genoa percentage due to any variations in leech (clew height)length. Any authorities out there care to enlighten or refer to a knowledgeable source?

Rick Sylvester seems a bit closer IMHO,...
at least in checking with my sources. J length is a different measurement than mast to headsail tack cringle, but very close. Anything over a 110 jib is considered a genoa. I've never heard of a 111, or a 119 jib, but 135 and 150 genoas are common. I'm sure there is a technical source hanging around the internet that could enlighten us all. Terry

Maybe We Are Being Too Precise?
I guess thats why my wife sometimes calls me (disparagingly) 'Data". Anyhow, I checked a marine terminology source who confirms that a genoa is an overlapping jib. Having said that, the common practice amoung sailors I know is to call a 110 a working jib and a 120+ a genoa. Something of a 100 or less as a blade. I think these are casual terms that may vary by audience, and possibly location. Rick D.

Rick, I'm sure us web footers in the...
soggy NW will have a different definition than elsewhere. What little I could find on the internet basically called it a jib-genoa. So, I'm guessing a blade is also a storm or about a 20 jib? Terry

Where Are You Alan?
Check me on this. I believe a blade is a full-hoist jib with a higher clew and maybe an 80 or so used in high apparent wind... like storm conditions. Typically used on racers wanting to make weather in heavy going. I think it's similar to a storm jib in function, but not as extreme and keeping as much luff as possible for drive. Now, who remembers a blooper <smile> ? Rick D.

Rick, thanks for the vote of confidence.
Your post is correct. A genoa is an overlapping jib(an LP greater than 100%). A working jib (a #2) fills the triangle between the mast and headstay. A storm jib is an even smaller jib used in heavy weather. A storm jib(smaller than #4) is carried with a high cut clew. A blade jib is less than 100% and has a deck sweeping clew and may have battens to maintain flatness. Of course, a genoa with a high cut clew will overlap farther than the decksweeper of the same % but the decksweeper is much more efficient for beating to weather.
