Mike, Al gauges shown are for wire rigging. Frers 33 has ROD rigging.

Hi

I noticed on the tuning guide the numbers reported were the gauge =
readings rather than the translated numbers in pounds. I have also =
noted that Loos makes several models of these tension gauges and each =
would likely give a different number.
=20
Would it be possible to replay with not only the numbers you use for =
uppers, lowers, intermediates and forestay as the tension gauge numbers =
but if possible also the translated pounds value and the model of your =
tension gauge? If anyone knows the diameter of rod used in each that =
would be nice as well because if it differs from boat to boat it would =
affect the readings as well. Our former J boat rig tuning guide was ion =

Hi Mike,
=20
As I mentioned previously the Frers 33 is equipped with Rod Rigging. =
The Loos Gauge required is one that is made and calibrated for Rod =
Rigging. The procedure is to measure the rod on the instrument =
(calibration is on the side) then hook on the guage and check the rig =
tension and adjust as appropriate. The numbers are a lot simpler to =
keep track of than the pounds. As far as I know the readings are =
similar if not identical on all Rod Rigging Loose gauges. The reason =
for the variation in tension on different rigs is probably a reflection =
of the type of sailing done, competition and local conditions. Info on =
the gauge used is available at =
http://loosnaples.com/tension-gauges/rod-rigging-gauge.
=20
I believe all Loos Gauges made for rod rigging will give the same =
readings if they are used properly.

Hi Mike:

Sounds like you'll be racing your boat, always good to hear. I also came =
from a J-boat and I think you'll find the Frers mast is actually easier =
to tune. We got the forestay length and rake from the tuning guide and =
centered the mast before blocking. Then the shrouds were just a matter =
of sighting up the mast while under sail. First we tension the uppers a =
few turns with a wrench after hand tight. Then I work down, keeping the =
mast in column at the dock keeping the intermediates and lowers both a =
bit looser than the uppers. The goal is tight enough that the leeward =
upper does not go particularly slack in moderate breeze. I don't see any =
value in more tension than that. Because the shrouds are not swept back =
by more than an few inches, you are not controlling fore and aft mast =
bend with them. So it's really just a matter of going for a sail and =
making some adjustments to keep it straight under load. I sight with =
mast straight - minimal backstay and runner on so it is easier to judge =
if the mast is, hooking, falling off or just bending in column. I =
haven't seen the need for a Loos gauge. Finally if the breeze is really =
on we might take two turns on the headstay and one extra turn on the =
uppers before a race.=20
=20
Does anybody take a more scientific approach than we do?

class=3DMsoNormal>As I mentioned previously the Frers 33 is equipped =
with Rod Rigging. The Loos Gauge required is one that is made and =
calibrated for Rod Rigging. The procedure is to measure the rod on =
the instrument (calibration is on the side) then hook on the guage and =
check the rig tension and adjust as appropriate. The numbers are a =
lot simpler to keep track of than the pounds. As far as I know the =
readings are similar if not identical on all Rod Rigging Loose =
gauges. The reason for the variation in tension on different rigs =
is probably a reflection of the type of sailing done, competition =
and local conditions. Info on the gauge used is available at =
