anyone have an info,sheet on rigging tension ? we have a 2000 H 290 and have a lo oos guage but cant find any reference info..
thanks

The info you seek is inherent to the wire itself. Once you've got the mast centered and straight, adjust your tensions to about 10% based on the Loos gauge's interpretations based on the wire size.
I haven't downloaded these manuals, so I don't know if the tuning information you're looking for is here, but this looks promising.

thanks , have those manuals but no info on rigging using a lo ose guage. The guage itself has the tension pounds indicator but am wondering what Hunter B&R riggs should be using for recommended settings. 20% of breaking makes me a bit nervouse.
thanks for the input....

There's a point in tightening the standing rigging where further tightening doesn't increase the rig tension very much. At that point you are bending the boat.
That's the key. What is that bend? A one inch deflection takes less tension than a two inch deflection.
That deflection is consistent. It takes a set amount of tension to bend the mast to a given deflection. Use that as your tension guide. Pull your halyard tight along the mast, then tighten your stays until you get the bend you want. Tighten your diagonals until you just see that bend increase, then back off half a turn. Be sure to pay attention to port and starboard bend, keep her plumb left and right.

The B&R is a slightly different critter .. Some have backstays and the newer ones donn't.. Here is a paper on tuning it..

Colin, I have broken your concerns into two parts to facilitate a response. Tensioning a rig is part science and part rigger voodoo.
1. Lack of detailed specifications for the process of using a tool to tension your standing rigging. The tool you have is designed to give you a measurement of the individual wire tension applied to that wire. The required tension for any boat is not fixed number. It is an approximate for the wire you are tensioning based on the wire’s properties. I have heard it from rigger’s being ranged from 10 to 20 percent of wire breaking strength.
@Will Gilmore gives you key insight in that it is not all about the individual wire tension, but about the effect tensioning each of the wires is having on the mast and boat.
2. I can understand your “nervousness”. You want to get it right, yet not break your boat. The use of your loos gauge tool is to let you create a basic starting point. Once you get a balanced “in column” rig tension of 10% that’s where the voodoo begins.
Here is a good discussion on that voodoo rigging that occurs away from the dock out on the water.
Setting up your masthead standing rigging
Start by slackening all shrouds and stays until all feel very slack. Then, tighten the backstay (and therefore the forestay) to a few turns tighter than hand tight. Any runners, checkstays or othe…

Tensioning a rig is not about cranking hard on each wire to a tool specific value. It is more like tuning a guitar where you sneak up on all the strings tension at the same time. Once the side shrouds give you that initial 10% of wire tension, and the fore shroud sag is gone, it is time to go sailing and see if the boat responds properly.
