To achieve more bend in the mast (so depowere the sail) I would need to wind on more tension on the spreader shrouds. Correct? Any advice and experiance welcome. Regards

since all the side spreaders pull somewhat back, you would have to either loosen the lowers or tighten the uppers to creat mast bend. You should have a tention measuring device, so your rig doesn't end up too loose or too tight, which could effect performance or structural integrity. Jeff Peltier

Thanks but?

Thank you Jeff. It would appear that adjusting the cap shrouds and the lower shrouds means that tension or lack of on the fore stay thus the compression etc etc and so yes it is important. However although they can contribute to some mast bend the spreader shrouds I believe put the bend in the mast. Any more info and advice appreciated. Regards

Mark I have a 95 H26 which is the same set-up

as your 260 except the 260 might have 1 size smaller shroud wires. I bought a "Loos Tension Gauge" for the 3/16th inch shroud wires and adjusted my standing rigging to the Hunter specs. You also set the mast rake at this time. The gauge was about $47 U.S. and I purchased it at West Marine. I found the best way to do this with any hope of accuracy was to set all of my standing rigging with the boat in the water and loaded up for one of our weekend trips. When adjusting the mast rake I got off the boat and let it settle down to get a good reading. It was like buying a new J boat! It handles better and is a lot faster. To do this right allow 1/2 a day and about a 6 pack of your favorite beverage. I contacted Hunter Marine by e-mail and Greg responded back the same day with the tension figures and percentages required. I have found Hunter Marine very responsive with info needed for me to do my own repairs and adjustments. Ray S/V Speedy

Ray need figures

Ray, Can you send me the values for the rigging and I'll place them up on my web site for everyone. These rating were not in my manual. Jim S/V Java

Does work if...

you add an "s" to picture in the address. Or, you can remove "picture" from the address and cruise around in the Unix file system to see the pictures without the http stuff in the way. But I didn't find any tension amounts.

Don't know if this will help but...

I was adjusting the rigging on my H23 once and found that I could get a lot of mast bend by keeping the lower shrouds and the backstay slack and cranking the uppers in until there was no adjustment left in the turnbuckles. Then I tensioned the lower shrouds. I measured loads with my Loos gauge as I was doing this and found that the load in the uppers did not increase very much as they were being shortened.
