Mast Rake?

[Bob Rutland]

Our 84 H31 has a B&R rig. I think the mast has to much rake because when I look up it looks like a banana.Is this normal? I've tried loosing the backstay and tighting the headstay, but it had little affect on the rake.Is this due to mast pre-bend or am I going about tunning the rig incorrectly? If I let the main halyard hang free, how far off the mast should it be at the boom? Thanks,  Bob

Bob, A lot of are following your question.

Thanks for asking this question as a lot of us are trying to learn about the features and functions of a B&R rig. My 95 H26 has no backstay and I think I understand why this is and how it works, therefore I am very interested in the mast configuration on this set-up when using a backstay. I'm dumb, I know it, and I'm looking forward to the lesson. Good luck, Ray

Pre- Bend

You should have about 2% prebend which would be about 5-6" at the center of the Mast. You adjust the prebend by adjusting the small inner diamond cables. Two at the base of the mast Two At the base of the upper spreaders. The only thing the back stay does is adjust the head stay tension.

B@R RIG

I thought I finally found out that a b and r rigg does not have a main or back stay,gimme da scoop

Tom, early B&R rigs.....

still used the swept back spreaders, like on your boat, but had a split back stay. Why? I don't know. Bob

Why? Spreaders not raked as extremely.

My '89 H30 has this "mixed" rigging arrangement. I understand that the tripod support of the newer B&R rigs can be engineered to work well, but I feel that a sailboat "should" have a backstay! Every design decision on a boat is a compromise; there's no one "best" way.
