<DIV><FONT face=Arial size=2>Sorry about taking so long to respond. It took a
while to locate the info.</FONT></DIV>
<DIV><FONT face=Arial size=2>From my Loos Instructions, 1/4" wire breaking
strength is 8200 lbs and 3/16" is 4700 lbs. Additionally, Loos recommends 1/4"
forestay set to 1300 lbs, 1/4" shrouds set to 850 lbs, and 3/16 shrouds set to
500 lbs.</FONT></DIV>
<DIV><FONT face=Arial size=2>The relationship of forestay / backstay is
something I can't comment on directly since I've got roller furling on the
forestay and therefore can't easily measure the tension there. Loos makes the
statement, "Since the backstay makes a greater angle to the mast, the backstay
tension will be lower than the forestay tension."</FONT></DIV>

<DIV><BR></DIV><FONT size=1>How do these numbers fit with the general guidelne
that shrouds should be tensioned between 10 and 12% of the breaking strength
the wire? This is what the instructions for my Loos tension guide said and
that has been my guideline in the past. That worked on my old boat, a CAL 27
T-2. If the application of the rule to my "new" Alberg 30 is different, I
would like to know. I appreciate having this source of informatioin
avaliable.</FONT><BR><BR>>>> timmins@optonline.net 12/28/01 06:37PM
>>><BR>These are the conclusions I drew from the list when it was
published in May<BR><BR>Average tensions of the whole
list:<BR>Forestay/Backstay............733<BR>
Backstay only...................726<BR>
Forestay
only....................735.6<BR>Uppers.............................685<BR>Fwd
Lowers.....................495<BR>Aft
Lowers........................0 (loose)<BR><BR>Race Boats Only
Averages:<BR>Forestay only....................811<BR>No backstay
only<BR>Uppers..............................862<BR>Fwd
Lowers......................679<BR><BR>Based on these numbers and info taken
from Brion Toss's video on rig tuning<BR>(and his web site), This is how I set
up my mast.<BR>Starting with the mast vertical, tighten the forestay to
snug/tight but not<BR>to pull the mast forward of vertical.<BR>Tighten
the backstay to 625<BR>Tighten uppers to 750<BR>Tighten Fwd lowers to
620<BR>Tighten Aft lowers to slack/100<BR><BR>After sailing a bit, I reset the
backstay to 700<BR>These numbers worked very well for me and the boat was
nicely balanced.<BR><BR>Don't ask me to explain my logic anymore (this was
done in June). I just<BR>happened to come across my note sheet from doing the
job.<BR>All tensions were done with a Loos Model B, part # 90
gauge<BR><BR>Regards,<BR>Brian<BR>#497<BR>----- Original Message
