How much rake in B&R rig?

[jared1048]

Hello,

I recently replaced my standing rigging and im trying to get it tuned right. I have a manual that described the process but it doesn't mention how much rake should be in it.

Currently I'm having problems getting the rigging tension to 10-15% breaking strength without adding a **** ton of rake into the mast. We tightened the forestay once already but it looks like we need to tighten it more?

Boat is a 1985 Hunter 31.


Thanks,

I don't believe that a 1985 Hunter 31 has a B&R rig. Maybe that is part of your problem as you are using the wrong procedure.

If you tighted the forestay to take the rack out AND you have a B&R rig you better get some real help as the forestay has nothing to do with it and a B&R rig.

Yes, I'm 100% positive it is. 30 degree aft swept spreaders and not only diagonals but reverse diagonals to induce mast bend without backstay. Yes, it does have a backstay also I can confirm but the early models didn't. Heard people didn't trust the way it looked so they added the backstay more for looks than function. The aft spreaders act as a tripod with the forestay. I'm getting off topic though

Since the B&R rig has aft swept spreaders it can rake the mast back by shroud tension. When its pulled back its only resistance besides the mast is the forestay which is the only thing pulling "forward".

I'm not going to debate. Go on-line and get the Seldon tuning guide (too large for me to load it here)

Thanks Don. Guide is very detailed.

I usually concentrate more on eliminating forestay sag without adding rake, which means the forestay gets a lot of the tightening.
