Shroud Tension

[Black Jack]

I have a guide I use for tuning the San Juan 21. It is continually evolving and should only be considered a guide. But I have been successful with these number.

wind speed Headstay length Upper shroud Lower shroud
0 to 5 knts Approx 24' 7" 10 - 15 15 - 20
6 - 10 Approx 24' 5 " 15 - 20 20 - 25
11 - 15 Approx 24' 4" 20 - 25 26 - 32
16 - 20 Approx 24' 2 25 30 - 35
21 plus Approx 24' 1 30 35

Again this is only a guide using the Loose guage. I have played one end of the range or another based on sea condition and number of crew. Sailing with three big guys would make a difference from sailing with me and my two young children or sailing with two crew.

I hope others will offer their rig settings so we could all learn from each other. Nothing is set in stone and I try new settings all the time in an effort to learn and I add it to my tuning guide.
