Again, it depends on the location of the side stays and the type of mainsheet block structure installed on the boat. The mainsheet block on the M is connected to a vary stout traveler that is bolted with many large bolts directly through the Deck, into the Liner, and then into a very strong steel ladder that is then bolted again through the sole liner and into the hull. There is a reason WHY the mainsheet block structure on the M boat is so crazy over built - it is the main force pulling the boat through the water!kurz wrote:sorry just to answer: Is a backstay mormally to trim the mast/sail and not to hold the mast?? !!!
The side stays must also be well behind the mast to support the force of a fractional rig sail configuration.
On the X boat I think the mainsheet it just attached to the pedestal - I doubt the pedestal is strong enough to take the entire force of pulling the boat through the water.
It's also important where on the boom the mainsheet attaches - the further forward the mainsheet attaches to the boom the more force is exerted on the mainsheet and less force on the rest of the rig.
