Happy Friday to everyone
If I exceed 2000 psi on Touche's backstay, the hull flex will result in
separation of the aft 6-8 inches of the keel from the hull. It's only
cosmetic but I will have to re-fair it at the next haul out.

Possibly different diameter standing rigging.

Happy Friday to everyone. I've enjoyed the discussions this week.
2000 psi on a hydraulic backstay for a large keelboat is not very much and
seems overly conservative to me, particularly with the large headsails that
many of our boats have.
We used to routinely go to 4000 psi on a 33 foot Santa
I wish I could do that. Touche' has a rod back stay. Probably due to the
fact that it had a Hood SeaFoil fore stay when I purchased the boat.
For the younger folks, a Hood Seafoil was essentially a fairly large rod
with two grooves. Basically a rod version of a Tuff Luff. So rod opposed
rod.
I have a decal on my gauge with both psi and pounds shown. I have decals
for different size cylinders. My gauge is difficult to read, but a mark on
the gauge at the maximum allowable force is all I need to make sure I don't
go over.

Just to clarify the clarifications, the force will be the area of the
piston minus the area of the rod. The adjuster is pulling the wire/rod.

I check the tension on my backstay with my Loos tension gauge same way i do
shroud tension. the gauge on my Navtec Hydraulic backstay tensioner is also
clouded after many years but still readable and Its reading compares
favourably with the Loos gauge at 1200 psi which is what i carry on my
upper s
If the gauge was specially printed for the size of the piston, it might
actually read tension. If it is just a generic pressure gauge, tension
would be PSI x Area of Piston in Square Inches.
(i.e 1000 PSI on 2 square inches = 2,000 pounds of tension)

We had this discussion many years ago on this list.
I think I recall that this is tension (in pounds) on the wire/rod. I think
the reading on a hydraulic back stay adjuster gauge is pressure (in psi) on
the piston. If so, they are not the same.
I think you have to convert the psi reading to ten
12 matches
