"Black Stripes" on mast?

[Pat Turner]

Can anybody explain to me what the "Black Strips" on the mast referrs to? I'm having new sails made for my CD22.While the sail maker and I were looking over the boat and discussing sail design issues, he wondered if the sail plan for the boat would indicate where the "black stripes" would fall along the mast. It has something to do with sail design or building sails for different race configurations.
Can anybody shed some light on this topic,and better yet, does anybody know where those babies are on a CD22?

Thanks in advance,

Pat

I think he may be referring to draft stripes, in this case on your mains'l, which start at the luff and end at the leach. They're used to help you eyeball sail shape and are usually black. Check out the article in Feb SAIL magazine by Tom Hall. It shows how to use draft stripes to gauge how to shape your sails underway.

If he meant something different let us all know ;^)

Pat , I think those have something to do with a racing rule. They limit how high and low your mainsail can go. For sail design I think it has a lot to do with the length of the luff of your main. Just my two cents worth

Pat,
I do not race except in an occasional club race so my info may not be 100% accurate. I believe that for a given boat there should be a black band on both near the top of the mast and near the end of the boom. When in a race your competitors can readily see if you have hoisted a sail which is larger than the rules allow by checking if the sail extends past either of the black stripes. I do not know if the stripes are the same for all rules.
It is good that your sailmaker is interested in some of these details, but I would question any sailmaker who can't find out these dimensions for you or at least tell you where to find out. They tend to have databases of this sort of thing. It is part of their job. Unless you race it is not important, but who knows whether you will want to participate in a race someday. It would be a bummer to find out that your sails were too big and you had to keep your luff and outhaul tension low in order to keep legal.

Enjoy your new sails.

By International agreement 1" wide Black bands (white bands on dark masts) are used to denote the limits of designed mainsail measurements for any given boat. Thus there will be 3. One on the boom precisely the distance of your "E" measurement back from the mast. One on the mast even with the top of the boom (in its normal sailing position), and one at the top of the mast precisely the distance of your "P" measurement from the lower one. Yes, indeed their purpose is to make it readily apparent if you are using larger sails than those designed for your boat. Remember that it is the distance BETWEEN the bands that counts. Since they indicate absolute limits, theoretically the sail should never more than 'touch' the bands.
If you know your P & E then you know where the bands go.
