Bergstrom & Ridder have been designing rigs since 1972. The patented
characteristics of a B&R rig are the diagonal diamonds, in lieu of
running back stays, and swept back spreaders with a small mast
section. This rig was first seen on Thursday's Child, built in 1983.
That B&R rig was incorporated as a masthead rig with back stay on all
subsequent Hunters. In 1989, Thursday's Child was re- fit with a
fractional B&R rig with no backstay, a precursor of all the new Hunter
rigs.

B&R designs have been incorporated into Hunters for the past 21 years,
first through Isomat, then some other fabricators, and now Seldon

I wouldn't call that a B&R rig, for one things it's a masthead with a
backstay. It's got some of the elements of the B&R though, kind of a
*******ized stepchild. With the standing backstay, it can't have a big
roachy mainsail, with the wide double spreaders it can't set a genoa
properly.

No wonder you thought it was a horrible rig. This looks like it has all
the B&R faults and none of the benefits. What were they thinking?

Actually, the design paramaters for the B&R rig preclude any kind of
on the fly adjustments so dear to the racing sailor or compulsive
tweaker. Its set it and forget it, what you see is what you got.

As for the older B&R designs, you couldn't use a backstay tensioner.
If you cranked down on the back stay, you loosened the diagonals (not
good)

That's right. The newer Hunters have adapted the B&R rig from the
Hunter's Child. Chopped a lot of weight aloft by reducing the mast
section, adding mast support struts, deep swept spreaders reverse
diagonals and jumpers on some. It does save weight but adds a lot of
windage, causes a lot of chafe on the main down wind and is impossible
to adjust headstay tension.

I'd have guessed it was the other way around. I.e., the swept-back
spreaders compensate for the lack of runners, and that the characteristic
"diamond shrouds" keep the mast "in column" athwartships without the use of
conventional twin lowers.

That'd be my _first_ guess in any case.

You are correct. I got twisted around.
