Rig trends
« on: January 05, 2007, 20:59:45 PM »
I'm considering purchasing a used proto and updating with a carbon rig.  So what are the current trends in proto rig design? ...not so interested in wing masts, etc.

-2 or 3 spreader

-masthead or fractional ..what fraction

-full width spreaders, straight or curved, short lower spreaders for overlapping genoa

-spreader sweep angle

-PBO, rod, dyform

-tube weight, Ixx, Iyy

Any info appreciated.

ok, that is a difficult one to answer, i am not really up to date on that.
1,2, spreaders the most i believe, some 3.
most fractional
full straight slightly more then full curved
short lower spreader not rally populair anymore.
angle, no idea
pbo or rod (most i gues rod)
from 1.45 kg to more, inertia no idea. (if you do look at the old alu tubes and then you have the old numbers, carbon lower :)

well, the general trend nowdays is to keep the mast above the deck; years of testing on different platforms proved this to be the fastest configuration. Dropping the rig overboard, despite imminent and quite big reduction in weight, will not beneficially affect your boat speed. This has been tested and proved on numerous occasions too...

Sweep back.
Modern yacht go upt to 30. giving more longitudinal stability to the mast, hence no need of runners... but anyway the rules force you to have runners on your mast. Too much sweep back limmits your boom downwind angle pluss needs longer and hevier section speaders.
20-25 would give a good performing rig with a good stability for a good range of wind without needing the runners.

Basicaly on protos you go for less angle to gain more control on mast bend which you control with runners. On our boats it goes to about 12 degrees.
Of course you get more safety in manouvers with more angle.
Sailed Pogo2 of David Krizek last winter and must admit that big angle that Pogo features makes jibes much more fun and less scarry :)

it´s not a pussy boat so it has to have a tough rig - for a tough sailor, right?

Thanks for all the replies.

Leo, 1 spreader protos?  Seems like the mast would be very heavy to get enough strength.

The short lower spreaders looked like a good way to fit larger headsails, so why is it out of fashion.. maybe the separate chainplate locations requires more hull structure (weight)?

Andraz, I just looked at your website and I see you've got a carbon mast for sale.  Are you trying something different?  I don't expect you give up all your secrets, just trying to learn whats new.

1 spreader, find photo of mini Inkzone.

Italian rigging, why out of fashion (but still a few use it)... it does not give you meters extra cloth, just a bit.
And protos do need one jib 3 spis, not a genua normally, so they can choose a big genua, but that one is hard to reef down to a good sail that fills the gap between Genua and stormjib (fixed size). Makes a bit more sense in the serie.

I notice that on the Naus that it is a single spreader with no running or back stays plus it looks like a deck stepped mast section.
Any comments on this rig

you can use battens with furling jibs but they have to be parallel to the luff so they are not as effective. Look at what the J105s use for an example

And reefing is a bit more work too :)
