[dwight veinot via CnC-List]

C designs do better to weather when the mast has a bend to leward. I
think bend to leward has a significant effect on the slot with consequent
effect on smooth airflow over the sails.

Stus-List Re: Tuning questions - now Loos gauge accuracy

[Barry McKee via CnC-List]

Karl:

 

Section 4 of the C 29 Mk I Owner’s Manual gives guidance for tuning both at 
the dock and under sail.  I downloaded a copy from the cncphotoalbum website.

 

Hope this is helpful.

Thanks for all the input!

 

Two comments this morning. 

1 The cncphotoalbum site appears down, anyone have insight?  or a copy of the 
tuning article?

 

2 In some boats (thinking cal 20) leaving lowers loose and uppers just snug 
allowed the rig to bend to leeward and actually improve upwind speed without 
poor pointing.  Not sure how the aerodynamics of all that works but sure helped 
racing. Most of the cal 20 race crews actually removed the aft lowers.

 

as we aren't racing our CnC29 I'm tuning for safety and somewhat performance so 
all input is still welcome!

Hmmm.  Didn't think Loos gauges were terribly inaccurate.  Now I question them.

Guess a good rule is to use the same gauge only to return your rig to settings 
based on your experience on the water.

 

I might borrow a neighbor's gauge and compare it to mine.

FWIW, I used a Loos gauge for my rod rigging this past spring to equalize the 
tension of my upper and lower shrouds.  While sailing in a breeze, I noted that 
the lower shrouds were loose compared to the upper shrouds.  Go figure.

For wire rigging I tested my Loos gauge compared to the gauge on my Navtec
hydraulic backstay for tension in the backstay. The correlation was very
close and indiscernible given the small but calibrated gauge on the Navtec
unit.
