backstay adjustment

would it be correct to say that tightening the backstay on a masthead rig would only tension the forestay?
your thoughts please

no, not only, it also "stretches the mast's "belly" forward...but its less effective on sailshape than a fractional rig.

Huh? I thought you were supposed to use Raid for roaches. How do you use battens? That was why I bought a catalina... don't have no stinkin roaches on our boats!!

The roach:

The shape of a sail is seldom a perfect triangle. It is common for sailmakers to add an arc of extra material on the leech, outside a line drawn from the head to the clew. This additional part of the sail is known as the roach; mainsails usually have roaches, but they are very occasionally found on specialized jibs as well. They provide additional power for a given mast/boom size.

Since it cannot be supported by tension in the sail material (applied from the corners), it would flap uselessly unless some other provision were made for it. It is therefore supported by battens, held in batten pockets, which extend into the main portion of the sail.


CD.....Just in case

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Ok, would you help me with another definition. I am not sure about this one.

Boom.

1. a loud, explosive sound.

2. A part of the rigging of a sail boat which holds the bottom of the main sail.

3. The result of not using a preventer.

4. A sound followed by weeks of cursing, dry feet, and thousands of dollars.

5. An error made by a portugese sailor that CD will never let him forget about!
