Damn Dave, we've been relying on Archimedes' principle. No wonder you =
keep
beating us. Guess we're just old school.
=20
By the way, we've put together a Frers 33 super-group for the Thundermug
regatta. We've got the captains of First Edition, Risoluto and Pachyderm
together aboard Pachyderm to see if we can screw up Dave's chances for a
first overall in ECSA. For those outside of our area, Wolverine is =
currently
tied for first place against in the Eastern Connecticut Sailing =
Association
overall results. Bring it on Wolverine!

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 pounds =85.

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:
=20
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?

Wolverine uses Euler=92s Equations to compute rig tension, but sighting =

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 =
