Hello,
How is it possible "to have a bigger mainsail for the same measured
sailarea " ?


Ever heard of "roach"?

Oh ye of WILD IMAGINATION!

Please explain to this old dotard sailor, how a smaller sail is
cheating?

Explain to Ole Thom, How stretching the Luff of a sail by a foot is a
better adjustment than simply gather in the Draft without over stressing
the sail lines?

Explain to me, in my Dotage, how you can stretch a Luff without over
tensioning the Head of the sail? If you stretch the Luff a foot, you
will prodably invert the upper batten. You for sure, are going to lose
that parallel relationship of the upper batten and the boom. This
doesn't happen with a Cunningham adjustment.

By the way, how do you Cruising Wonders, stretch the Luff of the new,
supperior sail cloths that have very,very low stretch. ( In my Dotage, I
still remember Canvass sails and Hemp lines but those days are long
gone.) Even Polyster cloth with filler are destroyed by over tension.

Come up to date Simpeton! Get with the new programs in sailing as you
approch your Dotage. Don't stop learning, I haven't

P/S The new Gelcoat is going on the Boats bottom this week. We have made
a few minor adjustment to the profile and an awful lot of improvements
to the fairing. I'm expecting good results.

I'll be glad to get back to sailing and off this 'net

It is not a smaller sail. It is a larger sail hung in the prescribed triangle
so it has a full shape or big belly as the Brits might say. The sail only
fits in the triangle because it fits there loose. In order to flatten the
sail so it is efficient to windward it must be made larger than the
triangle allows. Normally this would be accomplished by uphauling
or downhauling provided there is fitted a sliding gooseneck on the boom.

Since this isn't allowed under the rules, the too large mainsail is pulled
flat at the luff by using a Cunningham cringle and tackle. This allows
the sail to be flattened but still remain in the triangle delineated by the
black marks. This is a cheat, plain and simple and anyone who does
not understand is certainly a dottering old fart.

It is a worse solution than drawing the entire boom down below the
black line. That is my point. But drawing the boom down is illegal
according to the rules.

The dacron can be and is stretched all the time when trimming sails.
My sail happens to have a bolt rope which is also made of polyester
so it stretches right along with the luff of the sail.

I hope you are becomming educated in your dotage.

If the boat is fitted with a sliding gooseneck as standard, where would the
lower black line be situated? At the top of the slide? At the bottom? Or, if
somewhere between, exactly where?

Neal,
I've never had a three bladed prop. I've had a Martec folding prop/
with streamlined tip for longer than I care to remember

According to to Donal and Scott, the Martec's are poor props.

How is this a cheat? Since it is designed in to most one design boats, it is merely a way
to encourage maximum adjustability without exceeding the designed sail area.

Only someone terrified of the concept of racing would call this a cheat.

Does it do its work in an aperture or is it riding on a strut?

One only needs 'maximum' adjustability to the upside
when the sail is already too large for the prescribed
triangle. A non cheating person when adjusting the
sail to a full condition would have the sail smaller
than the allowed triangle. Those who cheat have
the sail completely filling the triangle when it's
full and then they flatten it with a Cunningham
device to keep the flattening process from putting
the sail outside the constraints of the triangle.
